The Harmony XPS Universal safety relays are ideal for use in a variety of safety applications thanks to their selectable safety function and start option using rotary switches on the front. This reduces the number of variants of the devices you need, and the diagnostic function allows states to be easily transferred to a PLC, so that in the event of a fault, downtime is reduced by clear error information. The side connector for connecting to the XPSU safety relay enables direct operation without separate wiring of the control. This relay extension has 4 safe relay normally open contacts and 2 normally closed contacts as outputs. The supply voltage is 24 VAC/DC and the connections are made via removable screw terminals. Installation is done by snapping onto a top hat rail or screwing onto mounting plates. A uniquely numbered locking band is included to protect the settings under the transparent cover. A wide range of approvals enable international use.
