GE IC200ALG325 – VersaMax 8-Channel 13-Bit Analog Voltage Output Module

In stock

Product Introduction: The IC200ALG325, manufactured by General Electric (GE Fanuc Automation), is a high-density analog output module in the VersaMax I/O series. It converts digital control signals from the PLC into precision voltage outputs to drive analog field devices such as proportional valves, actuators, and chart recorders. Designed for high-channel-count applications requiring accurate and stable voltage control, it provides 8 independent single-ended outputs with 13-bit resolution, making it ideal for complex process control and industrial automation systems.

Key Features

13-Bit High-Resolution Output: Delivers precise voltage signals with 2.5mV step resolution for accurate control of analog devices.
Dual Voltage Range Support: Jumper-selectable bipolar (-10.24V to +10.24V) and unipolar (0V to +10.24V) ranges accommodate diverse field device requirements.
High-Density 8-Channel Design: Optimizes cabinet space by providing 8 voltage outputs in a compact VersaMax form factor.
Robust Electrical Isolation: 250VAC continuous isolation protects the PLC backplane from field-side electrical noise, voltage spikes, and ground loops.
LED Diagnostic Indicators:
- FLD PWR: Lights when external 24VDC field power is active.
- OK: Lights when backplane power is present and the module is operating normally.
Configurable Fail-Safe Behavior: Set to hold the last output value or default to 0V upon communication loss or power failure.
Hot-Swappable: Enables module replacement without system shutdown, reducing maintenance downtime.
Rugged Industrial Construction: Wide temperature tolerance and ruggedized components ensure reliability in harsh manufacturing and process environments.
