Hot sale in stock MTL5531 one channel barrier, MTL5531 MTL5000 range isolators large quantity in stock now!


The MTLx531 repeats a signal from a vibration sensor in a hazardous area, providing an output for a monitoring system in the safe area. The interface is compatible with 3-wire eddy-current probes and accelerometers or 2-wire current sensors; the selection is made by a switch on the side of the module.
