The DL4000-PM is a custom interface which is setup to Poll certain files from an A-B Power Monitor 3000 and sends the data to a specified Modbus Slave device and Register range. The DL4000-PM acts as a DF1 Half Duplex Master device to poll the Power Monitor. Translates the data into Modbus RTU and writes the data to a specified Modbus RTU slave device. Contact us for more information.

Easy Configuration
Using the supplied configuration program the DL4000-PM is setup to poll the following from an A-B Power Monitor. The Modbus Slave ID, DF1 Power Monitor Address, and Starting Modbus registers for all seven commands are configurable in the current version.

– F16 (11 elements)
– F17 (13 elements)
– F18 (10 elements)
– F19 (13 elements)
