SPECIFICATIONS

6.1 ANALOG INPUT MODEL

Function:

Uses Analog Input to set a pressure output signal.

Ranges:

4 - 20 mA dc or 1 - 5 Vdc

Input Impedance:

For 1 - 5 V > 330 K Ohms

 

For 4 - 20 mA > 250 Ohms, ±0.1%

Analog Fault Detector:

Stepper Motor is cut off when AI < 0.8 V, ±0.1V

6.2 RAISE/LOWER INPUT MODEL

Function:

Uses Raise and Lower Inputs to set a pres-

 

sure output signal. Input may be configured

 

to accept a continuous ON/OFF dc signal or

 

incrementing dc pulse signal.

Input Characteristics:

Opto-isolated and bi-polar. Limited to 47 V by

 

metal oxide varistor (MOV).

Types of Inputs Accepted:

May be configured for continuous dc input

 

signal (On or Off) or dc pulse incrementing

 

signal.

Continuous DC Input:

Maximum dc input level is a function of the

 

supply voltage as follows:

 

12V Model: 11 - 14 Vdc

 

24V Model: 22 - 28 Vdc

DC Pulse Incrementing Input:

Pulse rates adjustable from 0.110%/pulse to

 

1.830%/pulse. Pulse must be held in TRUE

 

state for time period necessary for Regulator

 

to reach the new output value. An input that

 

changes state before completion of an

 

operation will have its remaining pulse in-

 

crement discarded. The next complete pulse

 

starts a new increment.

Input Impedance:

For 12V Model: 1800 Ohms

 

For 24V Model: 4300 Ohms
