Relay Output Modules Series 90-70 GE Fanuc IC697MDL340

Configured for discrete digital switching in Series 90-70 PLC architectures, the GE Fanuc IC697MDL340, also cataloged as the IC697MDL340 Discrete Output Module, provides direct physical/electrical execution. This hardware component translates logic-state commands from the central processing unit into controlled electrical biases to drive external field loads.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Timing

The IC697MDL340 interfaces directly with the Series 90-70 backplane bus communication velocity architecture, ensuring synchronous data transfer rates aligned with the CPU scan cycle. The high-density I/O density scaling allows 16 completely isolated relay channels to process independent AC voltage potentials without physical cross-coupling. All execution delays conform to standard mechanical relay response profiles, providing reliable contact state changes across deterministic industrial control networks. Firmware flash compatibility guidelines mandate verified physical indexing with the slot keys to prevent asynchronous bus interference during power-up sequencing.

Frequently Asked Questions

Q: Does the IC697MDL340 support live hot-swap installation inside the backplane?

A: No. The Series 90-70 chassis architecture requires complete system power de-energization before inserting or removing the IC697MDL340 module to prevent backplane bus damage or data corruption.

Q: What is the maximum load current capacity when multiple outputs are active simultaneously?

A: Each individual output channel can switch up to 2 A at 120/240 VAC. However, total module thermal dissipation constraints require that the cumulative load current across all 16 channels must not exceed the specified maximum power boundaries outlined in the Series 90-70 thermal matrix.

Field Installation Guidelines

• Terminal Wiring Safety: Ensure all external AC power sources driving the relay field contacts are locked out and tagged out prior to connecting field wiring to the terminal block.
• Shielding and Grounding: Field wiring cables must follow standard high-voltage separation paths. Maintain physical isolation between the low-voltage PLC backplane logic wiring and the high-voltage AC output loops to eliminate electromagnetic interference.
• Terminal Block Engagement: Fully seat the removable terminal block into the front connector housing of the module. Secure the physical mechanical retention screws to prevent vibration-induced contact failure in high-vibration industrial environments.
