The PD540, PD550, PD560, and PD570 Nova Process & Temperature Controller product line has been discontinued. Orders will be filled while supplies last – check individual part numbers for availability. We expect to introduce a new line of temperature controllers in the third quarter of 2021.

The Nova PD560 is a digital meter that accepts a wide variety of process and temperature inputs and is available in 1/8 and 1/4 DIN sizes. Its universal input accepts thermocouple, RTD, and voltage inputs, and it can be easily configured for a 4-20 mA input. It is available with up to three (3) relays, a 4-20 mA analog outputs, two (2) digital inputs, and an RS485 serial communication option which includes protocols for master/slave set point control, Modbus® ASCII and RTU, as well as PC software.

Process Inputs

Inputs: Field selectable: 0.4 to 2.0 V, 1 to 5 V, 0 to 10 V, -10 to 20 mV, 0 to 100 mV. 4-20 mA input requires 100 Ω resistor connected across input terminals (order P/N: PDX-RES1).
Accuracy: ±0.1% FS ±1 count
Decimal Point: Up to 3 decimals: 9.999, 99.99, 999.9, or 9999
Calibration: All inputs are calibrated at the factory
Scale Range: User programmable over entire range
Transmitter Supply: 14 to 18 VDC @ 20 mA; available instead of retransmitting analog output; selection is made through the front panel.

Alarm Relays

Ratings: 1 Form C (SPDT) standard; rated 3 A @ 30 VDC or 3 A @ 250 VAC resistive load. 1 or 2 Form A (SPST) optional; rated 1 A @ 30 VDC or 1 A @ 250 VAC resistive load
High/Low Alarm: User may program any alarm for absolute high or low operation, forward or reverse (fail-safe) mode.
Alarm Deadband: 0-100% FS, user select
Alarm Delay: 0 to 99 minutes and 59 seconds
Reverse Operation (Fail-Safe): Programmable, independent for each alarm. Relay coils are energized in non-alarm condition. In case of power failure, relays will go to alarm state.
Forward Operation: Relay coils are energized in alarm condition. In case of power failure, relays will go to non-alarm state.
Auto Alarm Initialization: Normal and standby operation independent for each alarm. Normal alarms will reflect the state of the input to the meter at all times. Standby alarms will not trigger if the change to alarm state is a result of power up cycle, set point change, or alarm configuration change.
