The SC-2350 is a similar carrier with configurable TEDS (Transducer Electronic Data Sheet) connectors for connecting to smart TEDS sensors. These enclosures for SCC signal conditioning modules connect directly to 68-pin DAQ devices. They include sockets for SCC modules, along with screw terminals for convenient connection to digital I/O and counter/time (GPCTR) signals from the DAQ device. These carriers offer three power options to increase the flexibility of deployment. Sockets J17 through J20 access the two analog output channels and the GPCTR channels 0 and 1. SC-2345 Connector Block The SC-2345 includes 20 SCC sockets, labeled J1 through J20 (see Figure 1). Sockets J1 through J8 accommodate SCC modules for conditioning signals on the analog input channels of the DAQ device. For example, an SCC module plugged into socket J1 conditions signals for channels 0 and 8 of the device. You can use sockets J9 through J16 for either digital I/O modules or dual-stage analog input conditioning. When using dual-stage conditioning of analog inputs (for applicable modules only in the SC-2345 series carriers), wire your input signal to the first-stage module (in sockets J9 through J16). The SC-2345 routes the output signal of the first-stage SCC module to the input of the second stage SCC module internally (see Figure 2). When using sockets J9 through J16 for digital I/O, simply plug in a digital SCC module or the SCC-FT01 for custom digital applications. You can use any combination of SCC digital input or digital output modules. The digital I/O lines of E Series or Basic multifunction DAQ devices are configurable for input and output on a line-by-line basis. You can also access the DIO lines of the DAQ device using the screw terminal block. Figure 1.

The only differences are the orientation of some modules and the addition of I/O connector and interface panelettes. This carrier is available with either a side 68-pin connector (recommended for DAQCard products) or a rear 68-pin connector (recommended for DAQPad products). The SC-2345 with Configurable Connectors handles dual-stage conditioning and digital I/O modules. It also offers custom connectivity by adding panelettes along its front and rear panels. Select up to 18 panelettes for side-mount 68-pin versions, or 15 panelettes for rear-mount 68-pin versions. With I/O panelettes, you can connect your sensor directly to the SCC system. With interface panelettes, you can add hardware controls and displays to your system. Blank panelettes are also available to fill unused positions or for modification to fit your custom application needs. The SC-2350 contains a TEDS microcontroller with two digital lines per analog input channel for communication with Class II smart TEDS sensors (for more information on smart TEDS sensors refer to ni.com/sensors). Sensors Plug&Play™ The IEEE 1451.4 standard delivers plug-and-play capability to analog sensors. End users, systems integrators, and developers can automate the configuation of measurement systems for analog sensors. By defining an easy add-on approach that brings TEDS benefits to all types of sensors, the standard makes data acquisition systems easier to set up, configure, and maintain. The TEDS structure is compact and flexible enough to handle a very wide range of sensor requirements. Smart TEDS Sensors An IEEE 1451.4 smart TEDS sensor consists of the analog components and an embedded memory chip, which together provide the mixed-mode interface for analog and digital signals. A smart TEDS sensor identifies and describes itself – providing the manufacturer, sensor model number, serial number, measurement range, sensitivity, and calibration information. TEDS information resides on a memory chip (EEPROM) within the sensor and is accessed by measurement systems such as the SC-2350 via a simple low-cost serial interface. SC-2350 The SC-2350 includes 10 SCC module sockets, labeled J1 through J8, J17, and J18 (see Figure 3). Sockets J1 through J8 accommodate SCC modules for conditioning signals on the analog input channels of the DAQ device. For example, an SCC module plugged into socket J1 would condition signals for channels 0 and 8 of the device. You can use sockets J17 and J18 for SCC modules that condition analog signals on the output channels of the DAQ device. Figure 3.

For 19 in. rack systems, choose the rack-mount kit. If you are using two SCC systems, or a single SCC system with a DAQPad device, choose the stacking kit to mechanically attach both systems. Power Options SC-2345 and SC-2350 carriers have three power options: • SCC-PWR01 – 5 VDC from the DAQ device or an external supply • SCC-PWR02 – universal AC external supply • SCC-PWR03 – 7 to 42 VDC external supply module (power supply not included) One power module is included with your carrier. Power modules are sold separately in case you want to use your SC-2345 or SC-2350 in two or more configurations. If you choose the SCC-PWR01, it is possible to power your SCC system with the internal power source of your DAQ device. NI DAQCards and DAQPads provide 800 mW of total power (480 mW of analog power) from their internal source. NI PCI and PXI devices provide 4.50 W of total power (1.74 W of analog power) from their internal source. If the power draw from your SCC modules is greater than the power available from your DAQ device, then you must use an external power source. The SCC-PWR02 includes an AC transformer. However, you must purchase an additional power cord to match your country’s power requirements. The SCC-PWR03 does not include a transformer but can be used with an external transformer that provides 7 to 42 VDC.

SC-2345/SC-2350 Panelette Options Panelettes If you choose either of the two versions of the SC-2345 with configurable connectors or the SC-2350 as your carrier, then you can install connectivity and interface panelettes to customize your SCC system. Panelette options (see Table 1, Figure 4) include BNC, SMB, LEMO (B-Series), MIL-Spec, banana jack, thermocouple plug, 9-pin D-Sub connectors, rocker switches, toggle switches, momentary switches, potentiometers, and LEDs. Please note, some panelettes occupy more than one panelette slot. All panelettes except for the strain-relief options include lead wires that you connect to the screw terminals of any SCC module or to the 42-pin screw terminal block inside the SC-2345 or SC-2350. The thermocouple and minithermocouple jack connector wires are made of the appropriate metals to avoid forming unwanted cold junctions. Cabling You connect your SC-2345 or SC-2350 to your DAQ device using standard cables. To determine the cabling needed for your configuration, see Table 2.
