Hardware Specifications

Industrial Control and Drive Characteristics

• Backplane bus communication velocity: The module maintains standardized communication timing with the PLC backplane, ensuring deterministic command propagation from the processor to the AC switching elements.
• Profinet / EtherNet/IP deterministic networks: The output circuitry is engineered to minimize transition jitter, supporting integration into control systems where precise timing of AC load activation is required for process stability.
• I/O density scaling: The 16-point configuration facilitates high-density load switching within a single module, supporting compact control panel designs for multi-circuit AC device management.
• Firmware flash compatibility: The module design maintains compatibility with standard PLC backplane addressing protocols, ensuring seamless recognition by the controller during system initialization.

Frequently Asked Questions

Q: Can this module drive loads exceeding 2 A per circuit?

A: No. The individual circuit limit is 2 A. Exceeding this rating will cause thermal degradation or failure of internal switching components. Total module current must not exceed 12 A.

Q: Is the module protected against output short circuits?

A: No. The module does not feature internal short-circuit protection. External fusing must be installed on each output circuit to protect the switching electronics from overcurrent conditions.

Field Installation Guidelines

• Mounting: Seat the module firmly into the designated PLC rack slot. Verify the backplane connector is fully engaged and secure the module via the integrated locking mechanism.
• Grounding: Connect the module common reference to the cabinet's protective earth (PE) bus. A stable ground reference is mandatory for the consistent operation of AC switching circuits.
• Wiring: Maintain strict physical separation between 115 VAC output wiring and low-voltage signal or communication cables. Use appropriately rated wire gauges for the load current and ensure all terminal connections are torqued securely.
