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.
* Default configuration from factory
Regardless of the wetting voltage, all of our devices are limited to sourcing 5mA.
| Product | DC Voltage | Max frequency in Hz (@ 50% duty cycle) |
| A7810 | 3.3 | 10*, 50, 100 (configurable) |
| A8812 | 5 | 10 |
| A8332 | 5 | 10 |
| A8911 | 3.3 | 10*, 50, 100 (configurable) |
| R9120 | 3.3 | 10*, 50, 100, 250 (configurable) |
