MTL5113P AND 5114P
FAILSAFE
SWITCH/PROXIMITY
DETECTOR INTERFACE
LFD option
With the MTL5113P/5114P, a fail-safe switch/proximity detector
located in the hazardous area can control an isolated fail-safe
electronic output. The MTL5113P units provide line-fault detection
alarm contacts. The MTL5113P and MTL5114P are for use with P + F
TÜV approved fail-safe sensors.
