This XPSECME safety module allows to expand the number of safety contacts available on XPS base modules. It meets the requirements of PL c/Category 2 conforming to EN/ISO 13849-1.and SILCL1 conforming to EN/IEC 61508 and EN/IEC 62061. Used in conjunction with XU2S single-beam photo-electric sensors (periodically tested), it establishes a category 2 light curtain conforming to IEC/EN 61496 parts 1 and 2. 24V AC/DC supply allows direct supply via an auxiliary transformer, like ABT7 or ABL6, allowing saving at installation time. Removable terminals for easier and better control wires tightening, thus improving installation reliability.
