E-TC Ethernet-based 8-Channel Thermocouple Input Device Features • Eight 24-bit differential thermocouple (TC) inputs with TC channel-to-host isolation − 4 S/s per channel maximum sample rate − Two integrated cold junction compensation (CJC) sensors − Open thermocouple detection − Supports J, K, R, S, T, N, E, and B type thermocouples • 8 digital I/O isolated from TC inputs and host The E-TC devices offers eight thermocouple channels and eight DIO channels which are bitconfigurable for input or output. Output bits can be further configured as thermocouple alarms. − ±24 mA drive capability • 10/100 Ethernet interface Overview The E-TC offers high-accuracy temperature measurement with an Ethernet interface. The device offers the best value per channel and the best possible accuracy because the accuracy of the internal measurement electronics exceeds the accuracy specifications of the thermocouple sensors. The E-TC is functionally equivalent to the USB-TC, making application migration very easy. Ethernet Interface Digital I/O The E-TC has a built-in high-speed communication port. Users can remotely access and configure the device with software over the Internet. The E-TC has eight digital I/O channels that are electrically isolated from the analog circuits. Each bit is individually configurable for input or output. Thermocouple Input Connect up to eight differential thermocouple (TC) input channels to the E-TC. The E-TC supports a maximum sample rate of 4 S/s per channel, and TC types J, K, R, S, T, N, E, and B. TC types are software-selectable per channel. Cold-Junction Compensation The E-TC has two high-resolution coldjunction compensation (CJC) sensors (one per four TC inputs). Open-Thermocouple Detection The E-TC is equipped with open-thermocouple detection (OTD) for all TC input channels. With OTD enabled, users can monitor for broken or disconnected TCs. Measurement Computing − Digital outputs configurable as TC alarms Data can be transferred at rates up to 5 kS/s when the device and host are connected by Ethernet to the same local network. Typical throughput is system-dependent. • Required +5 V external power adapter included Supported Operating Systems • Windows 11/10/8/7/Vista® 32/64-bit • Linux® • Android™ Use the alarm outputs to control a device or application that indicates when a temperature threshold has been exceeded, or to indicate an OTC condition. Counter Input The 32-bit event counter pin counts TTL pulses, and accepts frequency inputs up to 10 MHz. All DIO channels are pulled high by default to 5 V through 47 kΩ resistors with a jumper on the circuit board. Each jumper configures the digital port for pull-up or pull-down. The E-TC requires external power from the 5 volt, 1 amp power adapter (PS-5V1AEPS) included with the device. Temperature Alarms Calibration Each digital output can be optionally configured as an alarm for each TC input. When an alarm is enabled, the output line associated with the alarm is driven to the appropriate state determined by the alarm options and input temperature. The E-TC is factory-calibrated using a NIST-traceable calibration process. Specifications are guaranteed for one year. For calibration beyond one year, return the device to the factory for recalibration.

The accuracy specifications assume the device is operated within its enclosure and has been warmed up for the recommended 20 minutes. Errors shown do not include inherent thermocouple error. Contact your thermocouple supplier for details on the actual thermocouple accuracy error. When thermocouples are attached to conductive surfaces, the voltage differential between multiple thermocouples must remain within ±1.8 V.
