2 — INSTALLATION & WIRING: I/O Signal Specifications
Analog output
A single line is available as a low power analog output and is intended to drive
instrumentation such as a battery discharge indicator. is output is generated
from a filtered PWM signal and has about 1% ripple. e 2% settling time is
<25ms for a 0–5V step and <30 ms for a 0–10V step. is output line is pro-
tected against shorts to B+ or B-. Note: e 1232E/SE has no analog output.

Power supply outputs
Two lines provide auxiliary output power for low power circuits such as elec-
tronic throttles, LED indicators, displays, position encoder, and remote I/O
boards. I/O Ground (at pin 7) is the return line for these low power devices.
Both power supply outputs are protected against shorts to B+ or B-.
