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
