Information About 440R-EM4R2
The 440R-EM4R2 is part of the Allen-Bradley Guardmaster 440R series of safety relays, developed to provide reliable, cost-effective safety monitoring for machinery. This module supports dual-channel safety inputs for connection to devices such as emergency stop buttons, safety interlock switches, and protective sensors. It provides 4 normally open (NO) safety outputs and 2 normally closed (NC) auxiliary contacts for signaling and control flexibility. The relay is designed to meet SIL 3 (IEC 61508) and PLe (ISO 13849-1) safety requirements, ensuring compliance with global machine safety standards. DIN rail–mounted and compact, the 440R-EM4R2 includes LED status indicators for simple diagnostics, making it easy to integrate and maintain in safety systems.
Key Features:
- Design: Compact Guardmaster safety relay for machine safety monitoring.
- Inputs: Dual-channel inputs for E-stops, interlocks, and safety sensors.
- Outputs: 4 NO safety outputs and 2 NC auxiliary contacts.
- Safety Rating: Certified to SIL 3 and PLe standards for functional safety.
- Diagnostics: LED indicators provide status and fault monitoring.
- Compatibility: Works with a wide range of Allen-Bradley safety devices.
- Installation: DIN rail mounting for easy panel integration.
- Application Range: Suitable for emergency stops, light curtains, gate switches, and machine guarding.
The 440R-EM4R2 delivers the reliability, compliance, and protection required for modern safety-critical automation systems.
