NOTE
Do not exceed SSR maximum voltage 48
AC peak/DC and maximum load current 400
mA.
Also accessible via Audio jack connector
(see Figures 2 & 25)
Common (return) for pin 6 (0-5Vdc or
0-10 Vdc or 4-20 mA)
Also accessible via Audio jack connector
(see Figures 2 & 25).
Output. Do not apply external voltage
or any current source. Be sure to observe
recommended load impedance.
Power input 9 – 26 Vdc.
Power input and RS-232 communication
common.
4-20 mA analog output requires at least 12 Vdc power.
