Analog Outputs can be either 0 to -10 Vdc or 0 to +10 Vdc
(by Hydraulics Control Relay - see Programming and Setup)
Output current limited to approx. 3mA.

12 Vdc regulated supply load must be limited to
maximum current of 10 mA.
If external supply is used, tie supply minus (-)
to 12 Vdc Common.
High Level Excitation is from external regulated supply.
If transducer does not have built-in Cal resistor, insert resistor
shown between EX (-) and Terminal 5.
If resistor is NOT built-in, use value specified by manufacturer.

Analog Inputs must have minimum
Span of 8 Vdc to maintain max. resolution.
See Programming and Setup for 5 Vdc Spans.

Note that certain transducers
may require the installation of an
optical isolator between the transducer
output and analog input terminals.
