MCC TC-32 High-Precision Thermocouple Measurement USB/Ethernet System

The Measurement Computing TC-32 is a thermocouple (TC) measurement DAQ system. The TC-32 is ideal for high-channel count temperature applications. The system can also be rack-mounted. The TC-32 can communicate with a host device through either USB or 10/100 Ethernet. By offering both USB and Ethernet ports, the TC-32 is the perfect solution for local or remote monitoring.

The TC-32 provides 32 channels of 24-bit resolution. The TC-32-EXP expansion device adds 32 high-precision channels to support larger installations. Accuracy is designed into the product with sigma-delta 24-bit ADCs, differential inputs, TC-to-host isolation and cold-junction compensation (CJC) for each channel to reduce the effects of thermal gradients.

The TC-32-EXP expansion device doubles the number of TC inputs (64), digital inputs (16), and digital outputs/ alarms (64). The TC-32-EXP connects to the host TC-32 through a 40-pin expansion connector. The host TC-32 provides all power to the TC-32-EXP The TC-32-EXP supports all of the TC input and digital I/O features of the host TC-32, including built-in cold-junction compensation and open thermocouple detection.

Users can connect up to 32 differential TC input channels using the four groups of eight mini-jack connectors on the front panel of each device. Both the TC-32 and TC-32-EXP support a maximum sample rate of 3 S/s per channel, and TC types J, K, R, S, T, N, E, and B. TC types are software-selectable per channel.

Each TC input on TC-32 devices has a high-resolution CJC sensor that provides a local cold-junction temperature reference point. This feature ensures the highest level of temperature measurement accuracy.

TC-32 devices are equipped with open thermocouple detection for all TC input channels. When enabled, it allows users to monitor their TCs and determine if they are broken or disconnected.

The TC-32 provides up to 8 digital inputs and 32 digital outputs (16 and 64 when using with TC-32-EXP) that are electrically isolated from the host device and from the TC-32 analog circuits. This configuration allows users to optionally configure a digital output as an alarm for each TC channel. When configured as an alarm, the digital output line is driven to the appropriate state determined by the alarm options and input temperature. Users can also use the alarm outputs to control a device or application that indicates; when a software-selectable temperature threshold has been exceeded, when an open TC has been detected, and when the common mode voltage is out of range.

The TC-32 requires external power. A 5 V, 10 W power adapter is included with the TC-32. The TC-32 provides power to the TC-32-EXP when they are connected.
