Pulse Counter Device Compatibility


New member
Leviton has several pulse collector devices which use a low voltage and pull up resistor to detect a contact being in an open or closed state. This is a common way to provide remote capture of the usage counter from a metering device. The following information are the specifications of each of our pulse counting devices in one location to quickly determine which may be compatible with a third party pulse output submetering device.

ProductDC VoltageMax frequency in Hz (@ 50% duty cycle)
A78103.310*, 50, 100 (configurable)
A89113.310*, 50, 100 (configurable)
R91203.310*, 50, 100, 250 (configurable)

* Default configuration from factory

Regardless of the wetting voltage, all of our devices are limited to sourcing 5mA.
