In conjunction with a base unit the unit is used as a Contact expansion module to in- crease the number of contacts available on a base unit. Base units are all safety relays with feedback loop monitoring. Pulse relay Zulassungen In accordance with EN ISO 12100-1 and EN ISO 12100-2 (inching circuit for limited movement of hazard- ous machine components during installation, set up and position- ing) in safety circuits in accordance with VDE 0113 and EN 60204-1 (e.g. on movable guards) Safe timer relays in accordance with EN 1088 (re- lease with delay through timer) in safety circuits in accordance with VDE 0113-1 and EN 60204- 1 (e.g. on movable guards) The category that can be achieved in accordance with EN 954-1 and EN ISO 13849-1 depends on the cate- gory of the base unit. The contact ex- pansion module may not exceed this. Pilz GmbH & Co.
