The TC-4 PLUS is 4 channel type-K thermocouple amplifier device that can be used a stand-alone system or as part of a MTS (Modular Tuning System). The TC-4 PLUS includes a digital input/output, 4 full-programmable analog outputs, and is ideal for applications such as dynamometers, data acquisition systems, or standalone ECUs. The TC-4 is also a key component of Innovate Motorsports' Modular Tuning System (MTS).
