Product Short Description
Product Introduction: The IC200ALG331-KD is a 4-channel, 16-bit analog output module from GE Fanuc’s VersaMax series (now under Emerson Automation), featuring fully software-configurable voltage (±10 VDC) or current (4-20 mA) outputs with individual channel isolation. It eliminates jumpers/switches via factory calibration, supports per-channel default/hold last state, field recalibration, and detailed diagnostics (open wire, over/under-range, field power loss). It uses 1500 VAC isolation between channels and logic/frame ground, requires external 24 VDC for current mode, and integrates with VersaMax CPUs/NIUs for precision industrial control.
