Safety Relays


MSI-T - Safety monitoring device
CE TÜV Rheinland cUL listed TÜV Rheinland

MSI-T is a safety monitoring device for the periodic testing of "testable" optoelectronic protective devices.

The two components, both the safety sensor as well as the MSI-T relay, together form an AOPD acc. to IEC/EN 61496-1, -2. Up to 6 type 2 sensors can be connected to the MSI-T via a series connection.

In addition to testable Leuze electronic type 2 Single Light Beam Safety Devices, type 2 Multiple Light Beam Safety Devices of the MLD 300 series can also be connected to the relay. The machine's functional sequence remains unimpaired by the periodic internal function tests.
