The Snooper PD865 is an 1/8 DIN Modbus® meter that can be programmed as a Modbus® RTU master, slave, or snooper.
In snooper mode, the PD865 listens to the Modbus traffic and displays a process variable being transmitted on the bus.
As a master, the Snooper can read up to 8 Modbus variables; it will display one and make the other variables available for other Snoopers to display in snooper mode.
As a slave, a Modbus variable may be written to the PD865 by a Modbus master.
The PD865 is available with two (2) relays, 4-20 mA analog output, and multi-pump alternation control.
