Expand the capabilities of other Modbus® RTU serial devices with Precision Digital's PD865 Snooper. It has a six-digit sunlight-readable display and can be programmed as a master or slave in an RS-485 bus. As a Master, the Snooper reads a slave device, scales the data from it, displays the result, and operates the internal relays and 4-20 mA output. As a Slave, the data sent to the PD865 by the master is scaled, displayed, and used to operate the relays and 4-20 mA output.

PD865 Snooper, with a Modbus output level transmitter, can be used to control and alternate up to four pumps. Its multipoint linearization feature can be used to display the volume in a round horizontal tank or any other non-linear vessel. It can also generate a 4-20 mA output that is linear to volume. The PD865 is available with a wide variety of NEMA 4, NEMA 4X, and explosion-proof enclosures.
