Emerson Process Management Bristol Series 9110 - Manual (Page 52)

Specifications 6-2 CI-9110
6.3 GUARD INPUT
Enables or inhibits command signal input on both Analog and raise/Lower models.
6.4 ANALOG OUTPUT
Function:
Current feedback signal tracks the output of
the Remote Set Regulator. Signal is typically
used to telemeter pressure output value back
to the command site.
Range:
4 - 20 mA common ground type output
Load Resistance:
380 Ohms Max.
6.5 ACCURACY - ANALOG MODELS
Electrical Input to Pressure Output: ±5% of span
Pressure output to Feedback:
±
5% of span
6.6 ACCURACY - RAISE/LOWER MODELS
Feedback Volts to Pressure Output:
±
5% of span
Pulse Input to Pressure Output:
±
20% of span
6.7 DC POWER
12 Volt Model:
11 - 14 Vdc @ 0.35 A Max.
24 Volt Model:
22 - 28 Vdc @ 0.25 A Max.
Fuse:
1 A, 250 Vdc, 3AG
6.8 STEPPER DRIVE MECHANISM
Stepper Motor:
Gearing from motor shaft to pressure
regulator assembly results in approximately
22,000 incremental steps for 100% output
range travel.
Output Rate of Change:
Full scale sweep adjustable from 1.8 to 69.4
minutes.
Environmental Effects:
±
1.0% Max. full scale per 50°F (28°C)
Supply Voltage Effect:
±
0.15% Max. full scale per 1 volt change
