Safely reduce cabling and reduce costs
Schneider Electric has introduced its new Preventa XCSDM3 and XCSDM4 Hall-effect non-contact safety switches, from Telemecanique, a brand of Schneider Electric, which have been designed to eliminate the need for an external safety relay to monitor safety circuit input and output integrity.
Compact, easy to install and highly tolerant to misalignment, magnetic safety switches are used as safety interlocks on movable machine guards and/or where frequent wash down takes place. Standard safety switches are wired back to a panel with a safety relay for failsafe operation.
The new XCSDM3 and 4 models incorporate a safety relay enabling the devices to self-check and detect their own failure without the use of an additional external safety relays. They can directly drive two external 24V DC contactor coils (via two internally OSSD safety PNP outputs) and, in the case of the XCSDM4, monitor those external contactors' normally closed auxiliaries (known as EDM) to directly and safely control electric motor driven loads.
