FEATURES

The PD570 Series of Limit Controllers come equipped with a limit control latching relay, alarm relay, and a 4-20 mA retransmitting output. These standard features make the Limit Controller an excellent process monitoring tool. Serial communications for Modbus or PC monitoring software expands the Limit Controller’s capability.


 

OPERATING DISPLAYS

Nova Limit Controllers have dual four-digit LEDs and display the PV, limit set point, relay status, and limit operation information.

Operating Display Navigation

Thermocouple: J, K, T, E, R, B, S, L, N, U, W, Platinel II
RTD: Pt100 (0.00385), JPt100 (0.00392)
Process: -10 to 20 mV, 0 to 100 mV
0.4 to 2 V, 1 to 5 V, 0 to 10 V
4 to 20 mA input with a resistor shunt

 
 

OPERATION

Powerful Relay Functionality

All PD570 Series Limit Controllers have a 3 A Form C (SPDT) latching relay for use in limit control functions. All PD570 Series controllers also have a 1 A Form A (SPST) alarm relay.
  • High or Low PV Limit Latching Relay
     
  • Forward and Reverse (Fail-Safe) Latching and Alarm Relays
     
  • High/Low and Set Point Deviation Alarms
     
  • Fail-Safe and Standby Alarms
  • Relay Delays and Reset Deadband
     

Latching Relay Over Limit Control

When an over limit condition occurs, the latching relay will trigger. The relay must be reset manually and can only be reset once the input returns to normal operating conditions as established by the set point and programmable hysteresis.

4-20 mA Retransmitting Output

A 4-20 mA powered output is standard on all PD570 Series models. The output can be programmed to transmit over any input scale for any input type or based on the set point value.

Transmitter Loop Power Supply

The 4-20 mA retransmitting output may be configured to provide a 14 to 18 VDC @ 20 mA transmitter power supply.

Input Bias Adjustment

Up to five bias points set to specific input values can be used to provide precise offset adjustments through 4 bias zones. The controller will use the offset to create a smooth input value curve leading up to the bias points.

Max/Min Input Readings

Easily view the maximum or minimum input value reached during over limit conditions without entering the setup menus.

Display Over Limit Time

A timer to track the over limit times in minutes and seconds or hours and minutes is easily displayed from the operating menu.

Serial Communications & Adapters

Nova controllers with the serial communications option can be used for data acquisition or Modbus communication (RTU and ASCII). Nova controllers transmit via RS-485. The PDA7485 RS-232 to RS-485 and PDA8485 USB to RS-485 converters are available for use with the Nova Multi-Monitoring software or other PC applications.

Simultaneously View Up to 30 Nova Controllers



Remote Set Point Control and Indication

A detailed operation screen for each controller indicates the model number of the controller, the PV, SP, alarm conditions, high or low PV input, and the over limit condition timer.

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 100Ω 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.

Limit Control Relay and Indicators

Ratings: Latching, 1 Form C (SPDT); rated 3 A @ 30 VDC or 3 A @ 250 VAC resistive load
Relay Operation: User may select high or low limit operation, forward or reverse (fail-safe) mode.
Reverse Operation (Fail-Safe): Programmable; relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.
Forward Operation: Relay coil is energized in alarm condition. In case of power failure, relay will go to non-alarm state.
Hysteresis: 0-10% FS, user selectable; manual reset allowed after condition has been corrected.
Out LED: Relay status indicator. LED is on when relay is de-energized (during over limit conditions in reverse operation).
Over Limit LED: Over LED is on when system is in over limit condition. LED will go off once system returns to normal condition.
Over Limit Timer Display: Time stored since last occurrence of over limit condition or until controller is turned off.

Alarm Relays

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