Product overview
MTL4504 1channel DI relay output + LFD alarm + phase reversal
MTL4504 original isolated barrier with some models in stock now!
MTL4504 product specification as below
MTL4504 1channel DI relay output + LFD alarm + phase reversal
MTL4504 SWITCH/
PROXIMITY DETECTOR INTERFACE 1-channel with LFD and phase reversal
The MTL4504
enables a safe–area load to be controlled, through a relay, by a proximity
detector or switch located in a hazardous area. Line faults are signalled
through a separate relay and indicated on the top of the module. MTBF
information for the LFD relay is available from Eaton to allow the failure rate
for the LFD relay to be calculated when used in the critical path with the
output relay for safety critical applications. Switches are provided to select
phase reversal and to enable the line fault detection.
