MTL5532 - Pulse Isolator
Pulse & 4/20mA current outputs
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 legac 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.
