Installation Guidelines
- Ensure the Bus Interface Unit (BIU) is powered down before installing or removing the module to prevent electrical damage.
- Mount the module securely onto the designated DIN-rail, ensuring proper alignment with the terminal base.
- Use appropriate wire gauges (AWG #14-22) and ensure terminals are tightened to manufacturer specifications to maintain contact integrity.
- Maintain proper clearance around the module to facilitate adequate ventilation and cooling.
- Keep signal wiring separated from high-voltage or high-EMI sources to minimize noise and interference.
FAQ
What is the primary function of the IC670MDL740?
This module acts as a 16-point sourcing output interface for the GE Field Control system, allowing the PLC to control external DC loads such as solenoids, relays, and indicators.
Can this module be used for higher current requirements?
No, the IC670MDL740 is limited to 0.5A per point. For higher current applications, consider the IC670MDL742 (1.0A per point) or the IC670MDL730 (2.0A per point).
How is the module protected?
The output group is protected by a 5 Amp, 250V (5x20mm) slow-acting fuse, which includes a visual status indicator on the module faceplate.
