ifm electronic's AC041S safety relay can be used as a stand-alone relay or as part of an AS-interface Safety at Work network. The device complies with EN 954-1/SC 4, IEC 61508/SIL3 and EN ISO13849-1/PLe. As a two-ch
ifm electronic's AC041S
safety relay can be used as a
stand-alone relay or as part
of an AS-interface Safety at
Work network. The device
complies with EN 954-1/SC
4, IEC 61508/SIL3 and EN
ISO13849-1/PLe.
As a two-channel AS-interface safety monitor, it has USB 2.0 interface and a chip card to back-up settings. The USB is for configuration and diagnosis on a PC with ifm's user-friendly safety software. As a stand-alone safety relay, the AC041S has four safe inputs or eight standard inputs/outputs locally. ifm says it's becoming more common with control devices to be able to configure a connection as input or output; the AC041S is no exception. Outputs are solid-state and can be used with relay expansion modules, also available from ifm.
