Appendix Figure B-8: Current Output Board Wiring Diagram (Type A)
Type B:
Analog Input/Output board has two ±5 VDC differential inputs
(Appendix Figure B-9) and two user definable 0-20/4-20 or 20-4/20-0
mA outputs (Appendix Figure B-6).

Analog inputs are +/-5 VDC. Jumpers W3 and/or W4 are used to select 240 ohm
impedance for 0-20/4-20 mA inputs (see Appendix Figure B-10).
Type:
Differential voltage input
(0-20 mA or 4-20 mA with internal
resistor, jumper selectable)
Range:
0-5 volt, or ±5 volt, programmable
Input impedance:
100 k nominal (differential)
Maximum usable input voltage:
106% of full scale
Non-isolated
Max. non-destructive input voltage:
12 V peak
Field wiring: Connections are made to the terminal strip on bottom edge
of the analog board. Note that connector is removable for ease of
termination.
