Emerson Process Management CI-9110 Thermostat User Manual


 
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
