M-402 - Analog Input Module - Temperature / Low Level Signals
(Supports Hot Swap and Device ID)
Part Number
M-402 (8 Low Signal Input for TC, RDT, mV and Ohm)
Description
This module measures temperature from a large variety of Thermocouples (TC) and RTD’s as well
as miliVolts and resistance with high accuracy. Temperature measurements are internally linearized
and in the case of TC’s, a cold junction compensation is already built-in close to the terminals of the
module.

IMPORTANT
During the process, if there was the need of replacing the M-402 module, it must be
reconfigured. For more details, see the LC700 – Configuration Manual.

NOTES
To comply with the EMC standards, use shielded cables in signal inputs (ground the shield in the
panel only in one side of the cable).
