ifm efector AS-i safety monitor with USB interface

The AS-i safety monitor from ifm efector monitors the transmitted code sequences in the AS-i network. In the case of message deviations or timeouts, it ensures the safe state of the system.

The safety monitor enables the transmission of safe and non-safe I/O signals via the same AS-i bus. The safety-related extension is fully downward compatible and can be retrofitted on existing installations. All masters, power supplies and bus components can also be used.

The safety monitor can be integrated into the AS-i system at any position. Several AS-i safety monitors can be operated via one AS-i master. Parameter setting of the functions known from the safety relays such as “E-STOP”, “stop categories 0 or 1”, “two-hand control” or “enable switch” can be done via the software using the USB interface. The company claims that one AS-i safety monitor can replace multiple traditional safety relays. When a device is replaced the data can be saved on a chip card.

The device has four safe inputs or eight standard inputs/outputs, plus two safe semiconductor outputs and six triggerable outputs in the field. It is certified to EN 62061/SIL3, IEC 61508/SIL3 and EN ISO 13849-1/PL e.
