Safely reduce cabling, lower costs and use less panel space
01 May 2008
Schneider Electric has introduced its Preventa XCSDM3 and XCSDM4 Hall Effect non-contact safety switches, from Telemecanique, 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 24VDC contactor coils and, in the case of the XCSDM4, monitor those external contactors’ normally closed auxiliaries to control electric motor driven loads directly and safely.
Certified for use in SIL2/Cat3 and SIL3/Cat4 safety circuits, the devices offer a wide range of benefits for OEMs and end users. The main advantage is the convenience of buying a single device, which reduces cabling complexity and panel space.
The devices permit up to nine approach directions and are magnetically coded to prevent tampering, ensuring security. Pre-wired versions (2m, 5m and 10m) are available, as well as M12 connector versions for ease of maintenance.
