440R-E23097 | Allen-Bradley Safety Relay MSR132EP Minotaur, 4NO 2NC, 24V AC/DC

The 440R-E23097 is an Allen-Bradley safety relay, model MSR132EP, designed to monitor and control safety circuits in industrial environments. It ensures safe machine operation by integrating emergency stop devices, light curtains, and safety switches. The relay offers 4 normally open (NO) and 2 normally closed (NC) outputs, providing flexibility for safety logic configurations. Operating at 24V AC/DC, it’s compatible with most industrial control voltages. It meets Category 4 safety requirements, making it suitable for applications requiring the highest reliability.

The relay operates on a 24V AC/DC power supply, making it highly versatile for industrial automation systems. This dual-mode input ensures compatibility with both AC control transformers and DC control buses. Voltage tolerance enables stable operation even in environments with slight voltage fluctuations. Proper wiring and grounding must be observed for full safety compliance. Using stabilized power improves relay responsiveness and lifespan.

No, the MSR132EP model has a fixed delay time of 0 seconds, meaning all safety outputs are activated or deactivated immediately upon input change. This is essential for applications requiring instantaneous shutdowns. While this version doesn’t support time-delayed outputs, other models in the Minotaur family may offer configurable delays. Fast response time contributes to Category 4 safety compliance. The immediate output is critical for emergency stop circuits.

Yes, the 440R-E23097 features removable terminal blocks, which greatly simplify installation and service. This allows technicians to pre-wire terminals and then snap them into the relay body during final assembly. Removable terminals also aid in fast relay replacement without rewiring. Each terminal is clearly labeled for error-free connection. This modularity saves time and minimizes wiring errors.

Yes, the relay supports output switching of both AC loads (up to 250V, 6A) and DC loads (up to 24V, 3A). This makes it adaptable to various control elements, including contactors, solenoids, and indicator lights. The contacts are rated for industrial switching cycles and are protected against overloads. Users must size loads appropriately and protect circuits with external fuses or breakers. The relay’s contact lifespan depends on load type and switching frequency.
