What it is and where it fits
The Mitsubishi FX5-4LC is an analog input module from the FX5 series, offering 4 input points and 4 output points with a choice of control methods: two-position, PID, heating/cooling PID, and cascade control. It draws about 0.20 mA sensor current when paired with a resistance thermometer and presents an input impedance of 1 MΩ or more. Occupied I/O is 8 points, so it doesn't eat up your backplane budget.
