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 required 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 required function can be easily set from 6 selectable safety functions. Mechanical contacts from emergency stop/stop buttons, position switches, magnetic switches, two-hand operation type IIIA, electronic PNP sensors, light curtains or RFID safety switches with OSSD outputs can be connected to the inputs. Automatic, manual or monitored start as well as an optional start-up test are available for the start function. This safety switching device has 1 safe relay changeover contact and 1 diagnostic message as an output. With the help of the qualified diagnostics, states and errors are detected and transferred to a standard input of a PLC using a telegram via direct wiring. A ready-made function block for common control systems evaluates these messages so that the operator is fully informed on the machine display. The supply voltage is 48-240 VAC/DC and the connections are made via removable screw terminals. Applications up to safety level PL c in category 1 or SIL1 can be realized. Installation is done by snapping onto a top hat rail or screwing onto mounting plates. A uniquely numbered locking strap is included to protect the settings under the transparent cover. A wide range of approvals enable international use.
