MTL4501-SR FAIL-SAFE SWITCH/PROXIMITYDETECTOR INTERFACE with LFD.

MTL4501-SR FAIL-SAFE SWITCH/PROXIMITYDETECTOR INTERFACE with LFD.

With the MTLx501-SR, a fail-safe switch/proximity detector located in the hazardous area can control an isolated fail-safe
electronic output. The MTLx501-SR also provides relay alarm contacts to signal line-fault conditions. The MTLx501-SR is for use with approved
fail-safe sensors in loops that require operation up to SIL3 according to the functional safety standard IEC 61508.
