GE IC695MDL765 Smart Digital Output Module

Configured for high-density discrete signal execution in PACSystems RX3i control platforms, the GE IC695MDL765 (IC695MDL765 Smart Digital Output Module) provides direct physical/electrical execution of 24/125 Vdc output control and Electronic Short Circuit Protection (ESCP) for 16 discrete points.

Hardware Specifications

Industrial Control and Network Characteristics

• Backplane bus communication velocity: The module utilizes the high-speed PCI-based RX3i backplane, enabling deterministic data exchange between the CPU and the output points. This velocity is necessary to support high-speed switching requirements in automated production environments.
• Profinet / EtherNet/IP deterministic networks: When integrated into an RX3i remote I/O rack, the module facilitates deterministic output state updates over industrial Ethernet networks. The module's internal logic handles point-to-point state processing with minimal propagation delay, ensuring synchronous operation across distributed I/O stations.
• I/O density scaling: The 16-point architecture allows for efficient control cabinet layout, supporting high-density logic execution within a single RX3i rack slot while providing granular electronic protection for each channel.
• Firmware flash compatibility: The module supports field-upgradeable firmware, ensuring ongoing compatibility with evolving controller platform revisions and maintaining the security and functional integrity of the output control logic.

Frequently Asked Questions

Q: Does the ESCP (Electronic Short Circuit Protection) require manual resetting?

A: No, the ESCP is an electronic protection feature. Once a short circuit or overcurrent condition is cleared from the field side, the module is designed to reset automatically, though the specific fault must be acknowledged in the controller software to restore normal output operations.

Q: Can this module be hot-swapped while the rack is powered?

A: Yes, the IC695MDL765 supports hot-insertion and extraction within the RX3i backplane. Ensure that the module is properly seated and the locking mechanism is engaged to maintain bus communication and prevent intermittent output states during the transition.

Field Installation Guidelines

• Mounting: Secure the module into the designated RX3i rack slot, ensuring the backplane connector pins are fully mated. Use the integrated release latches to lock the module in place, providing mechanical support against vibration and thermal expansion.
• Grounding: Terminate the module's common return and chassis ground pins to the cabinet's low-impedance earth bus. This is mandatory for the effective operation of the ESCP circuits and to provide a robust return path for high-frequency switching currents.
• Wiring: Utilize shielded cabling for long output runs to mitigate inductive interference. Keep discrete output lines separated from high-voltage AC cabling by at least 150 mm to prevent crosstalk and ensure the integrity of the 125 Vdc signal levels.
