The TC-32 and TC-32-EXP offer exceptional performance and accuracy for thermocouple (TC) measurement applications at a low cost per channel. Offering both Ethernet and USB ports, the TC-32 provides 32 channels of 24-bit resolution for medium channel installations. The TC-32-EXP 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. With digital alarming notifications when a temperature exceeds programmed limits, the TC-32 and TC-32-EXP offer the perfect solution for temperature monitoring applications including server rooms, refrigerated storage, and long-run test cells.

Ethernet interface: The TC-32 has a built-in 10/100 BASE-T auto-negotiation, high-speed communication port. With the Ethernet interface, you can remotely access and configure your TC-32 from anywhere on the network. Only one computer can control the TC-32 at a time. A unique media access control (MAC) address is assigned to each device at the factory. You configure the Ethernet connection settings through software. The network name uses the format TC-32-xxxxxx, where xxxxxx are the lower six digits of the factory-assigned MAC address.

USB interface: The TC-32 is a USB 2.0 full-speed device that is compatible with USB 3.0 ports. The device is also compatible with USB 1.1 ports.
