The GE Fanuc IC200ALG320, also cataloged as the IC200ALG320 Analog Output Module, operates as a dedicated hardware component for multi-channel analog current signal generation within VersaMax I/O platforms. The unit executes digital-to-analog signal conversion across 4 current-sourcing channels, delivering 4-20 mA control signals to field actuators and positioning devices.

The module interfaced through the VersaMax backplane structure operates with a maximum update rate of 0.3 ms, processing 12-bit output directives sent from the CPU or network interface unit. Output channel logic draws up to 50 mA from the internal 5 VDC system bus while utilizing external 12/24 VDC user side power for field-loop actuation. Upon fault detection or loss of backplane communication, the hardware executes configurable fail-safe states, reverting channels to 4 mA or holding the last valid output state via jumper selection.
Q: Does the IC200ALG320 require an external power supply to operate field output loops?
A: Yes, while logic power is derived from the 5 VDC backplane bus (50 mA max), the analog output channels require external field power rated at 18 to 30 VDC or 9.6 to 15 VDC.
Q: What fail-safe output response modes are available upon CPU stoppage or fault?
A: The module can be configured via jumper settings to either hold the last known output state or drop the output signal to 4 mA.
Q: How does the module indicate operating status and field power presence?
A: The module contains 2 onboard LED indicators: the OK LED confirms backplane power supply and system initialization, while the FLD PWR LED confirms active user side field power.
