MTL5532 PULSE ISOLATO MTL 5532 PULSE ISOLATO

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.
