The Reliance Electric 61C345A Analog Input Module is a four‑channel rail‑mount analog input card for Reliance AutoMax/AutoMate PLC systems. It accepts four independent 4–20 mA transmitter signals and interfaces with the controller on the 45C1 Digital I/O Rail, delivering each analog input to the backplane for processing by the PLC. This module is used to capture field transmitter outputs in process‑control installations, providing four isolated 4–20 mA inputs that integrate with the AutoMax/AutoMate backplane. In catalogs this part is listed as 61C345A (also seen as 61C‑345‑A).
