GENERAL INFORMATION
The ARM2 will accept a single analog (voltage or
current) signal and split that signal into two DC
non-isolated current sourcing outputs that can be
re-scaled. Its primary application is as a signal splitter.
The outputs are always scaled identically and will
always track each other. The top-adjust trimmer
potentiometers can be used to make fine adjustments
to output ranges for maximum flexibility. This device
can attenuate an input signal to 100%. The ARM2 also
has an adjustable gain and offset. The output gain can
be adjusted from 1 to 20 times the input (gain will vary
depending on input). The ARM2 also has the ability to
reverse an input signal.
MOUNTING INSTRUCTIONS
Circuit board may be mounted in any position. If
circuit board slides out of snap track, a
nonconductive “stop” may be required. Use only
fingers to remove board from snap track. Slide out
of snap track or push against side of snap track and
lift that side of the circuit board to remove.
Do not flex board or use tools.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect or disconnect wiring with power applied.
• When using a shielded cable, ground the shield only at the controller end. Grounding both
ends can cause a ground loop.
• It is recommended you use an isolated UL-listed class 2 transformer when powering the unit
with 24 VAC. Failure to wire the devices with the correct polarity when sharing transformers may
result in damage to any device powered by the shared transformer.
• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids,
or other inductors, each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor
(ACI Part: 142583), or diode placed across the coil or inductor. The cathode, or banded side of the
DC Transorb or diode, connects to the positive side of the power supply. Without these snubbers,
coils produce very large voltage spikes when de-energizing that can cause malfunction or
destruction of electronic circuits.
• All wiring must comply with all local and National Electric Codes.
