MTL5532 - Pulse Isolator

Pulse and Vibration modules
Single and dual channel modules are available to transfer vibration probe signals from a hazardous
area to a safe one. Similarly, pulses from a switch, proximity detector, current pulse transmitter or
voltage pulse transmitter, located in the hazardous area, can be safely transferred to the safe area.
MTL5532 - Pulse Isolator
Pulse & 4/20mA current outputs
The MTL5532 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, and the transistors used on the
pulse output will switch +ve or –ve polarity signals.
It may be used immediately in simple or legacy mode, or it may be software configured for more
specific applications - see next page for either option. With configuration, an analogue output
proportional to frequency is available, together with a relay output, which may act as an alarm.
Note: For reliable, long-term operation the load on the output switching relay should not be less
than 50mW, e.g.10mA at 5VDC.
