Allen-Bradley MSR310P Safety Relay Base

Allen-Bradley MSR310P Safety Relay Base

The Allen-Bradley 440R-W23219, also cataloged as the MSR310P safety relay base, serves as a modular safety relay interface for Guardmaster MSR300 family systems, providing configurable reset logic and communication diagnostics.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

Although the MSR310P communicates via RS-232 rather than Ethernet/IP, its modular integration into MSR300 architectures aligns with deterministic safety relay behavior. Expansion modules scale I/O density while maintaining predictable scan cycles. Firmware flash compatibility ensures uniform reset logic across connected modules, while RS-232 diagnostics provide deterministic monitoring of relay states.

Frequently Asked Questions

Q: Can the MSR310P be expanded for additional inputs and outputs? A: Yes, it connects with MSR300 expansion modules to increase input and output capacity.

Q: What reset modes are supported? A: The relay supports automatic, manual, and monitored manual reset configurations.

Q: How are diagnostics performed? A: Front-facing LED indicators and the RS-232 interface provide fault tracking and configuration monitoring.

Field Installation Guidelines

• Mount the 35 mm housing on DIN rail with secure retention.
• Ensure 24 VDC supply wiring is properly terminated and shielded.
• Configure reset type via RS-232 interface before commissioning.
• Route auxiliary outputs separately from safety-rated circuits.
• Verify LED indicators for PASS/FAULT and reset status during startup.
• Maintain separation of RS-232 cabling from high-voltage conductors.
