MTL 5500 Intrinsically Safe Isolators  MTL5532

MTL4532 – MTL5532 PULSE ISOLATOR pulse & 4/20mA current outputs
The MTLx532 isolates pulses from a switch, proximity detector, current pulse transmitter or voltage pulse transmitter located in a hazardous area. It is ideal for applications involving high pulse rates and fast response times, by repeating the pulses into the safe area. An analogue output proportional to frequency is also provided, together with a relay output, which may be configured to act as an alarm. Configuration is carried out with a personal computer.
