Relay, Single Function, Safety, with Delayed Outputs, 24V AC/DC

The Allen Bradley 440R-M23143 is a GuardMaster safety relay designed to manage safety functions with a time delay feature. This single-function relay operates at 24 volts AC/DC and is equipped with delayed safety outputs that can be set between 0.15 to 3 seconds, making it ideal for applications like light curtains where controlled timing is crucial. It includes both normally closed and normally open contacts for safety inputs and outputs, as well as removable terminals for easy wiring. Part of the wider MSR300 family, this relay supports modular expansion by connecting multiple input modules to a single base unit, allowing you to build scalable safety systems with up to 20 inputs and control across three separate zones. The logic configurations are straightforward and handled via rotary switches, eliminating the need for complex software setups. Distributed by BSP Automation, the 440R-M23143 relay offers a reliable solution for integrating safety controls into industrial systems with flexibility and precise timing options.
