Omega OM-USB-TC 8 Channel Thermocouple Input USB Data Acquisition Module
**USB Data Module new in seal package in Box with cable. Buyer can expect a working item. See photos for further details.
The OM-USB-TC is a USB 2.0 full-speed, thermocouple input module that is supported under popular Microsoft Windows operating systems e OMB-DAQ-2416 Series and OM-USB. Series Software User’s Guide. The OM-USB-TC is fully compatible with both USB 1.1 and USB 2.0 ports. The OM-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 OM-USB-TC, you can take measurements from type J, K, R, S, T, N, E, and B thermocouples. The OM-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 OM-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.
