Product Short Description
Product Introduction: The IC200ALG325 is an 8-channel, 13-bit voltage analog output module from GE Fanuc’s VersaMax series, converting digital data from PLCs into -10.24V to +10.24V DC (bipolar) or 0V to +10.24V DC (unipolar) voltage signals for industrial actuators/processes. It has 8 single-ended channels with a common return, requires external field power (user-side), and uses optical isolation between field circuits and logic/frame ground. It draws 50mA from the 5V backplane, supports software configuration for default/hold last state, and includes onboard diagnostics with LED indicators for reliable industrial control.
