A.4 E/D Process Module
The E/D module is configured for either an E/D module or an E module by positioning the module
TYPE jumper (JPD) in either the E/D or E position.
Each E/D or E module requires a specific address of 1 through 6. Position the jumpers address
(MOD) for A0, A1 and A2 as indicated in the jumper tables located on the PCB. There are 4
process Input Channels.
The E module provides pulse interpolation and double chronometry timers to provide Level A
pulse fidelity checking on Channels 3 or 4 to support small volume proving. This module also has
a Detector Switch Input.
Channels 1 and 2 can accept:
•
Analog input voltages (1-5 VDC)
•
Current inputs (4-20mA) converted to 1-5 VDC by installing the 4-20 jumper
•
Low level RTD input signals (0.20 - 0.55 VDC) by installing the RTD jumper, which increases
the signal input by a factor of 10X
Channels 3 and 4 can be configured for flowmeter pulses or densitometer frequency signals.
They can be configured for AC or DC signal coupling. Each input threshold can be adjusted for
1.5 or 3.5 Vpp, which makes it suitable for interfacing to Solartron type densitometers.
A.5 E/D Module Setup
Configure the E/D module as either an E/D module or E module by positioning the TYPE jumper
(JPD) as indicated in Figure A-5.
Assign a unique address to each E/D or E module installed into the OMNI flow computer by
positioning the jumper's address (MOD) as indicated in Figure A-5.
