1. Overview
The TC-4 device is 4 channel thermocouple interface device for a MTS Log Chain. The TC-4 may
also be used as a stand-alone 4 channel MTS compatible thermocouple amplifier (see Chapter 2
for more details).
Each of the four inputs of the TC-4 can be user configured either EGT range (32..1999 degF,
0..1093 degC) or for CHT range to measure cylinder head temperatures (32..572 degF, 0..300
degC.
