Information About 440R-B23020
The 440R-B23020 MSR5T safety relay from Allen-Bradley is engineered for machine safety applications requiring monitoring of emergency-stop circuits, safety gates, and other protective devices. It features two normally closed (NC) safety input channels, which can be configured for automatic or manual monitored reset. The relay outputs include three normally open (NO) safety outputs for direct control of contactors or actuators and one normally closed (NC) auxiliary output for status feedback to PLCs or indicator systems. With a slim 22.5 mm wide housing and universal 24V AC/DC input power, it fits seamlessly into compact safety control environments. The relay meets global safety certifications (UL, CE, CCC, KC, CUL) and conforms to Category 3 safety requirements, making it suitable for mid-level safety performance in industrial automation systems.
Key Features:
- 24V AC/DC Power Supply: Supports universal low-voltage control panels and flexible power integration.
- Dual-Channel Safety Inputs: Two normally closed (NC) inputs allow monitoring of safety devices like E-stops or gate switches.
- Three NO Safety Outputs: Redundant relay contacts for reliable actuation of safety contactors or actuators.
- One NC Auxiliary Output: For signaling or PLC feedback without compromising safety circuit integrity.
- Manual or Automatic Reset: Can be configured for manual reset with monitoring or automatic restart logic.
- Compact 22.5 mm Housing: Slim DIN rail mountable design conserves space in crowded control cabinets.
- Global Certification: Meets CCC, CE, UL, CUL, and KC safety standards for use in international applications.
- 0.5-Second Reset Delay: Built-in delay helps avoid nuisance resets in power-up or stop-start conditions.
- Category 3 Safety Rated: Suitable for medium-risk safety applications per EN ISO 13849-1.
- Reliable Electromechanical Design: Designed for high durability in industrial E-stop and interlock monitoring.
The 440R-B23020 MSR5T provides a compact, standards-compliant safety relay solution for mid-tier safety systems with flexible reset modes and high-output reliability.
