Material Group (DIN VDE 0110, 1/89, Table 1). All Broadcom data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. For creepage, the shortest distance path along the surface of a printed circuit board between the solder fillets of the input and output leads must be considered. There are recommended techniques such as grooves and ribs, which may be used on a printed circuit board to achieve desired creepage and clearances. Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level.

No external interface circuitry is required because the HCPL772X/072X use high-speed CMOS IC technology allowing CMOS logic to be connected directly to the inputs and outputs. As shown in Figure 10, the only external components required for proper operation are two bypass capacitors. Capacitor values should be between 0.01 μF and 0.1 μF. Each capacitor should be placed as close as possible to the input and output power-supply pins of the optocoupler.

In today’s manufacturing environment, however, automated systems are expected to help manage the process, not merely monitor it. With the advent of digital field bus communication networks such as CC-Link, DeviceNet, PROFIBUS, and Smart Distributed Systems (SDS), gone are the days of constrained information. Controllers can now receive multiple readings from field devices (sensors, actuators, etc.) in addition to diagnostic information. The physical model for each of these digital field bus communication networks is very similar as shown in Figure 11. Each includes one or more buses, an interface unit, optical isolation, transceiver, and sensing and/or actuating devices.

As network communication is bidirectional (involving receiving data from and transmitting data onto the network), two Broadcom optocouplers are needed. By providing galvanic isolation, data integrity is retained via noise reduction and the elimination of false signals. In addition, the network receives maximum protection from power system faults and ground loops. Within an isolated node, such as the DeviceNet Node shown in Figure 12, some of the node's components are referenced to a ground other than V– of the network. These components could include such things as devices with serial ports, parallel ports, RS-232 and RS-485 type ports. As shown in Figure 12, power from the network is used only for the transceiver and input (network) side of the optocouplers. Isolation of nodes connected to any of the three types of digital field bus networks is best achieved by using the HCPL-772X/ 072X optocouplers. For each network, the HCPL-772X/072X satisify the critical propagation delay and pulse width distortion requirements over the temperature range of 0°C to +85°C, and power supply voltage range of 4.5V to 5.5V.

It has data control and message-exchange function, as well as bit control function, and operates at the speed up to 10 Mb/s. The recommended CC-Link circuit is shown in Figure 13. Since the HCPL-772X/072X are fully compatible with CMOS logic level signals, the optocoupler is connected directly to the transceiver. Two bypass capacitors (with values between 0.01 μF and 0.1 μF) are required and should be located as close as possible to the input and output power supply pins of the HCPL772X/072X. The bypass capacitors are required because of the high-speed digital nature of the signals inside the optocoupler.

Isolated Node Powered by the Network This type of node is very flexible and as can be seen in Figure 14, is regarded as isolated because not all of its components have the same ground reference. Yet, all components are still powered by the network. This node contains two regulators: one is isolated and powers the CAN controller, node-specific application and isolated (node) side of the two optocouplers while the other is non-isolated. The non-isolated regulator supplies the transceiver and the non-isolated (network) half of the two optocouplers.

In this case, the transceiver and isolated (network) side of the two optocouplers are powered by the network. The rest of the node is powered by the AC line which is very beneficial when an application requires a significant amount of power. This method is also desirable as it does not heavily load the network. More importantly, the unique dual-inverting design of the HCPL-772X/072X ensure the network will not lock- up if either AC line power to the node is lost or the node powered-off. Specifically, when input power (VDD1) to the HCPL-772X/072X located in the transmit path is eliminated, a RECESSIVE bus state is ensured as the HCPL-772X/ 072X output voltage (VO) go HIGH. Bus V+ Sensing* It is suggested that the Bus V+ sense block shown in Figure 15 be implemented. A locally powered node with an unpowered isolated Physical Layer will accumulate errors and become bus-off if it attempts to transmit. The Bus V+ sense signal would be used to change the BOI attribute of the DeviceNet Object to the auto-reset (01) value. Refer to Volume 1, Section 5.5.3. This would cause the node to continually reset until bus power was detected. Once power was detected, the BOI attribute would be returned to the hold in bus-off (00) value. The BOI attribute should not be left in the auto-reset (01) value since this defeats the jabber protection capability of the CAN error confinement. Any inexpensive low-frequency optical isolator can be used to implement this feature.

The AC line powers a regulator which provides 5V locally. The AC line also powers a 24V isolated supply, which powers the network, and another 5V regulator, which, in turn, powers the transceiver and isolated (network) side of the two optocouplers. This method is recommended when there is a limited number of devices on the network, which do not require much power, thus eliminating the need for separate power supplies. More importantly, the unique dual-inverting design of the HCPL-772X/072X ensure the network will not lock- up if either AC line power to the node is lost or the node powered-off. Specifically, when input power (VDD1) to the HCPL-772X/072X located in the transmit path is eliminated, a RECESSIVE bus state is ensured as the HCPL-772X/ 072X output voltage (VO) go HIGH.

Since the HCPL-772X/072X are fully compatible with CMOS logic level signals, the optocoupler is connected directly to the CAN transceiver. Two bypass capacitors (with values between 0.01 µF and 0.1 µF) are required and should be located as close as possible to the input and output power-supply pins of the HCPL-772X/072X. The bypass capacitors are required because of the high-speed digital nature of the signals inside the optocoupler.

As shown in Figure 18, a PROFIBUS Controller (PBC) establishes the connection of a field automation unit (control or central processing station) or a field device to the transmission medium. The PBC consists of the line transceiver, optical isolation, frame character transmitter/receiver (UART), and the FDL/APP processor with the interface to the PROFIBUS user. Figure 18: PROFIBUS Controller (PBC) PROFIBUS USER: CONTROL STATION (CENTRAL PROCESSING) OR FIELD DEVICE USER INTERFACE FDL/APP PROCESSOR UART PBC OPTICAL ISOLATION TRANSCEIVER MEDIUM The recommended PROFIBUS application circuit is shown in Figure 19. Since the HCPL-772X/072X are fully compatible with CMOS logic level signals, the optocoupler is connected directly to the transceiver. Two bypass capacitors (with values between 0.01 μF and 0.1 μF) are required and should be located as close as possible to the input and output power-supply pins of the HCPL-772X/072X. The bypass capacitors are required because of the high-speed digital nature of the signals inside the optocoupler. Being very similar to multistation RS485 systems, the HCPL-061N optocoupler provides a transmit disable function which is necessary to make the bus free after each master/slave transmission cycle. Specifically, the HCPL-061N disables the transmitter of the line driver by putting it into a high state mode. In addition, the HCPL-061N switches the RX/TX driver IC into the listen mode. The HCPL-061N offers HCMOS compatibility and the high CMR performance (1 kV/μs at VCM = 1000V) essential in industrial communication interfaces.
