Emerson Process Management Series 9110, CI-9110 Analog Input Model, RAISE/LOWER Input Model

Chapter 6

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
