SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

manual or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

Do not use the P48 to directly command motors, valves, or other actuators not

equipped with safeguards. To do so can be potentially harmful to persons or

equipment in the event of a fault to the controller. An independent and redundant

process limit indicator with alarm outputs is strongly recommended.

“...” - Appears when display values exceed + display range.

“-..” - Appears when display values exceed - display range.

LED Status Annunciators:

%P - Lower auxiliary display shows power output in (%).

2. POWER:

AC Versions: 85 VAC min. to 250 VAC max., 50 to 60 Hz, 8 VA max.

DC Versions:

3. CONTROLS: Four front panel push buttons for modification and setup of

controller functions and one external user input for parameter lockout or other

functions.

4. MEMORY: Nonvolatile E

PROM retains all programmable parameters

and values.

5. RANGE AND ACCURACY:

* Accuracies are expressed as percentages after 20 minutes warm-up. The

controller’s accuracy is specified in two ways: accuracy over an 18 to 28°C

range at 10 to 75% RH environment; and accuracy over a 0 to 50°C range

at 0 to 85% RH (non-condensing) environment. Accuracy over the wide

sensor range reflects the coefficient of the internal circuitry.

6. MAIN SIGNAL INPUT:

Sample Period: 100 msec

Response Time: Less than 300 msec typ., 400 msec max. (to within 99% of

final value w/step input; typically, response is limited to response time of

sensor)

Normal Mode Rejection: 40 dB @ 50/60 Hz (improves with increased

digital filtering.)

Common Mode Rejection: Greater than 120 dB, DC to 60 Hz

Protection: Input overload 120 VAC max. for 15 sec. max.

7. USER INPUT: Internally pulled up to +5 VDC (1 M).

IN MAX

= 5.25 VDC;

= 0.85 V max.; V

= 3.65 V min.;

OFF

= 1μA max.

Response Time: 120 msec max.

Functions:

8. CONTROL AND ALARM OUTPUTS:

Relay outputs with Form A contacts:

Contact Rating: 3 A @ 250 VAC or 30 VDC (resistive load)

1/10 HP @ 120 VAC (inductive load)

Life Expectancy: 100,000 cycles at max. load rating.

(Decreasing load and/or increasing cycle time, increases life

expectancy.)

9. MAIN CONTROL:

Control: PID or ON/OFF

Output: Time proportioning or Linear DC

Cycle time: Programmable

Auto-tune: When selected, sets proportional band, integral time, and

derivative time values.

10. ALARMS: 1 or 2 alarms (optional)

Modes:

Reset Action: Programmable; automatic or latched

Standby Mode: Programmable; enable or disable

Hysteresis: Programmable

Annunciator: LED backlight for “A1”, “A2”

11. SECONDARY OUTPUT: Software selectable (overrides alarm 2)

Control: PID or ON/OFF

Output: Time Proportioning

Cycle time: Programmable

Proportional Gain Adjust: Programmable

Deadband /Overlap: Programmable

12. MAIN AND SECOND LINEAR DC OUTPUT: (optional)

Main: Control or re-transmission, programmable update rate from 0.1 sec to

250 sec

Second: Re-transmission only, fixed update rate of 0.1 sec

* Accuracies are expressed as percentages after 20 minutes warm-up. Output

accuracy is specified in two ways: Accuracy over an 18 to 28°C range at 10

to 75% RH environment; and accuracy over a 0 to 50°C range at 0 to 85%

RH (non-condensing) environment. Accuracy over the wide sensor range

reflects the coeffecient of the internal circuitry.

** Outputs are independently jumper selectable for either 10 V or 20 mA. The

output range may be field calibrated to yield approximately 10% overrange

and a small underrange (negative) signal.
