Allen Bradley Guardmaster Expansion Module Relay

The Allen Bradley Guardmaster 440-R series is a safety relay expansion module with a supply voltage of 24VDC. It has 4NO instantaneous outputs and 1PNP auxiliary output. The functionality of 2 standard safety relays can be achieved in one dual input (DI) device, allowing the connection of two dual-channel input devices into one safety relay. The single-wire safety connection simplifies cascading and expanding safety functions by linking relays with a single-wire connection. A dynamic signal from device to device provides a linkage in accordance with SIL 3 and PLe, allowing easy addition of extra I/O that can be configured with simple logic combinations. Also, ’and/or’ logic can be configured simply in a single relay or through a combination of relays via a single-wire connection.
