Product Name Type Connectivity Product Description
Model PD765 Trident Digital Panel MeterMonitoring HardwareModbus RTUModel PD765 Trident digital panel meter can be field programmed to accept process voltage (0-5V, 1-5V, etc) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples. It is housed in a shallow-depth, 1/8 DIN enclosure that features a NEMA 4X front panel and convenient mounting hardware.
Model PD865 SnooperRemote Terminal UnitModbusThe PD865 Snooper Modbus Serial Input Meter can be programmed as a Modbus RTU Master or Slave. 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, it is controlled by a master device. The data sent to it by the master is scaled, displayed, and used to operate the relays and 4-20 mA output.
Nova Process and Temperature Controllers, PD500 SeriesControllerModbusPrecision Digital's Nova Process and Temperature Controllers are a complete line of panel mounted control products. Designed to fit a wide range of applications, the Nova is available in various DIN sizes and includes a universal input as well as user configurable relay and analog outputs. Available models include the PD540 Series PID Controller, PD550 Series Ramp and Soak PID Controller, and the PD570 Series Limit Controller with latching relay.
