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.

“SENS” - Appears when measurement exceeds controller limits.
“...” - 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:
DC Power: 18 to 36 VDC; 7 W
AC Power: 24 VAC
10%; 50 to 60 Hz, 9 VA
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 2 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 ).

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.
