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 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 at terminals OUT2 or OUT3, instead of retransmitting analog output; selection is made through the front panel

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.
Relay Operation: Time proportional PID control, forward or reverse (fail-safe) alarms, inner signal PV or SP zones, program segment time signals, or program run or end alerts
Cycle Time: 1 to 300 seconds; time proportional PID control only.
High/Low Alarm: User may program any alarm for absolute high or low trigger values.
Deviation Alarm: User may program any relay for high, low, or high/low range set point deviation alarm.
Alarm Deadband: 0-100% FS, user selectable
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.
Inner Signal Zones (IS): Relay activates with inner signal 1 or 2 states, based on the value of the PV, SP, or target >SP of the program segment. Two programmable trigger value ranges.
Time Signal (TS): Relay activates during program segments with time signals.
Program Run (RUN): Relay activates during program operation.
Program End Alert (PEND): Relay activates for 15 seconds following reset at program completion.
Auto Alarm Initialization: Normal and standby operation independent for each alarm. Normal alarms will reflect the state of the input to the controller 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.

Temperature Inputs

Inputs: Factory calibrated, field selectable: J, K, T, E, B, R, S, L, U, N, W, and Platinel II thermocouples and 100 Ω platinum RTD (0.00385 or 0.00392 curve)
Cold Junction Reference: Automatic or off
Offset Adjustment: Four programmable input bias zones
Sensor Break: Up or down scale, user selectable; display reads S.OPN; alarm relays will follow the up or down scale selection.
