Description
Description
The IC670MDL241 is a 16-point discrete input module designed for the GE Fanuc Field Control I/O system. This module is engineered to monitor high-voltage AC signals, providing reliable interface capabilities for industrial control applications. It organizes its 16 inputs into two groups, allowing for flexible wiring and isolation between input sections. The module communicates with the Bus Interface Unit (BIU) to provide real-time status data to the controller.
Features
- 16 discrete input points organized into 2 groups of 8.
- Rated for 240 VAC nominal operation.
- 250 VAC continuous isolation between the two input groups.
- Integrated LED indicators for each input point and a module power (PWR) status LED.
- Designed for vertical mounting within the Field Control rack system.
- Internal circuitry includes a network of resistors and capacitors for input filtering and optoisolators for logic-to-field isolation.
Applications
- CNC Machinery and Metallurgy control systems.
- Oil, Gas, and Petrochemical process control.
- Automotive manufacturing assembly lines.
- Water treatment and municipal engineering systems.
- Plastic and textile manufacturing machinery.

Connections
Field devices such as pushbuttons, limit switches, or auxiliary contacts are connected between the 240 VAC "Hot" line and the specific input terminal. The neutral line is common for all points within a single group. Each group requires an external 240 VAC power source for operation.
Installation Guidelines
- Ensure the system power is disconnected before installing or removing the module from the rack.
- The module is designed for vertical mounting; ensure adequate clearance for airflow and cable management.
- Use shielded cabling for field inputs to minimize EMI interference in high-voltage environments.
- Verify that the Bus Interface Unit (BIU) is properly seated and providing logic power before commissioning.
- Observe ESD precautions when handling the module to prevent damage to internal sensitive electronic components.
