MODEL: 18JF  
Rack-mounted DCS Signal Conditioners 18-RACK  
POWER INPUT  
DC Power  
R: 24 V DC  
2-input MATH FUNCTION MODULE  
(field-programmable)  
(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)  
Functions & Features  
• Providing temperature or pressure compensation for a gas  
flow, and other arithmetic operations  
• Microprocessor based  
[2] OPTIONS  
Equation (Refer to the EQUATION table)  
/1: Temperature compensation for DP flowmeter (ideal gas)  
/2: Pressure compensation for DP flowmeter (ideal gas)  
/3: Addition/subtraction  
• Equation and parameters selectable on site via hand-held  
programmer PU-2x  
• Loop testing  
/4: Multiplication  
• Second channel output available at the front terminals  
and at the Standard Rack connector  
/5: Division  
EQUATION  
Equation parameters  
Typical Applications  
• Various flowmeters  
• Adding two flows  
X0: output (%)

2
: input (%)  
• Ratio calculation  
K0  
2: gain ±29.999  
• Calculating average temperature  
A0  
2: bias (%) ±299.99 %  
EQUATION  
/1: Temperature compensation for DP flowmeter (ideal gas)  
K1X1  
X0 =  
K2X2+A2  
where X0 : compensated flow (linear characteristic)  
X1 : uncompensated flow (square root extraction available)  
X2 : temperature  
/2: Pressure compensation for DP flowmeter (ideal gas)  
X0 = K1X1 K2X2+A2  
where X0 : compensated flow (linear characteristic)  
X1 : uncompensated flow (square root extraction available)  
X2 : pressure  
MODEL: 18JF–[1]66–R[2]  
/3: Addition/subtraction  
ORDERING INFORMATION  
• Code number: 18JF-[1]66-R[2]  
X0 = K0 {K1 (X1+A1) + K2 (X2+A2)} + A0  
/4: Multiplication  
Specify a code from below for each of [1] and [2].  
(e.g. 18JF-666-R/3)  
X0 = K0 (K1X1+A1) (K2X2+A2) + A0  
/5:Division  
Use Ordering Information Sheet (No. ESU-1980). Default  
setting will be used if not otherwise specified.
