Pulse isolator

MTL offer two pulse isolators, they both have same functionally but differ in connection and case style.  The MTL5532 are DIN rail mounted isolators; the MTL4532, are designed to be mounted on a backplane.  For simplicity, in many cases references are made to the MTL4532 module but the comments are equally applicable to the MTL5532 as well.  Also the spelling MTLx532 is used to indicate that the reference applies to both versions.

The pulse isolators take an high frequency signal from either a voltage pulse, current pulse or switch/proximity detector in hazardous area and repeats 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.

When selected by switches on the module the module is programmable by the PCS45 software and PCL45USB (or PCL45) hardware, which configures input source, current output data and digital functions.
