2.1.4 APAX-5018 12-ch Thermocouple Input Module
The APAX-5018 is a 16-bit, 12-channel thermocouple input module that features pro-
grammable input ranges on all channels. It accepts millivolt inputs (±50 mV, ±100 mV,
±500 mV), voltage inputs (±1 V, ±2.5 V), current input (±20 mA, 0~20mA, 4~20mA)
and thermocouple input (Type J, K, T, R, S, E, B). An external CJC on the plug-in ter-
minal is designed for accurate temperature measurement. The module provides
2500 VDC optical isolation between channels and backplane bus. If any high voltage
or current damage the channels, the whole system (backplanes, other modules, and
control unit) won't be affected because it is already isolated.
