The E-TC is functionally equivalent to the USB-TC from Measurement Computing, making application migration easy.

Ethernet Interface
The E-TC has a built-in high-speed communication port. Users can remotely access and configure the device with software over the Internet.

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 cold-junction 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.

Digital I/O
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.

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.

All DIO channels are pulled high by default to 5 V through 47 kOhm resistors with a jumper on the circuit board. Each jumper configures the digital port for pull-up or pull-down.

Temperature Alarms
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.

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.

The E-TC requires external power from the 5 volt, 1 amp power adapter (PS-5V1AEPS) included with the device.

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 E-TC also offers field calibration so that users can calibrate a device locally.
