USB-based 8-channel thermocouple input module.
The USB-TC is a USB 2.0 full-speed, thermocouple input module that is supported under popular Microsoft® Windows® operating systems. The USB-TC is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-TC provides eight differential thermocouple input channels. Eight independent, TTL-compatible digital I/O channels are provided to monitor TTL-level inputs, communicate with external devices, and to generate alarms. The digital I/O channels are software programmable for input or output.
With the USB-TC, you can take measurements from type J, K, R, S, T, N, E, and B thermocouples.
The USB-TC provides two integrated cold junction compensation (CJC) sensors for thermocouple measurements.
An open thermocouple detection feature lets you detect a broken thermocouple. An on-board microprocessor automatically linearizes the measurement data.
The USB-TC is a standalone plug-and-play module which draws power from the USB cable. No external power supply is required. All configurable options are software programmable.
The USB-TC is fully software calibrated.
