INTRODUCTION
The analog scaling module is used for analog signal conversion
or re-scaling. It will accept one DC voltage, current or resistive
input signal and output a non-isolated voltage or current
signal. The output signal is easily calibrated for various offsets
and spans can be direct or reverse acting to provide signal
inversion.
The device also includes a regulated power output that can
be used to power a transducer or a resistance input. It features
top-adjust trim-pots for offset, gain, input attenuation and
reverse-offset calibration. There is also an LED power indicator.
The product comes with standard snap-track for easy mounting or is also available mounted in a hinged
ABS enclosure
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the device. Failure to follow these
instructions may result in product damage. Do not use in an explosive or hazardous environment, with
combustible or flammable gases, as a safety or emergency stop device or in any other application where
failure of the product could result in personal injury.
Take electrostatic discharge precautions during
installation and do not exceed the device ratings.
MOUNTING
The snap-track device may be mounted in any position. Use only fingers to remove the PCB from the
snap-track, do not pry on the PCB with tools. Do not flex the PCB during removal or installation. Slide the
PCB out of the snap-track. See Figure 1. Ensure any metallic mounting hardware does not contact the
underside of the PCB.
Avoid mounting in areas where the device is exposed to vibrations
or rapid temperature changes. Mount the snap track with the PCB
removed using two screws as shown in Figure 2.
Once the snap track is mounted, place one side of the PCB into the
snap track and gently press the other side of the PCB with two fingers
evenly placed at each corner until the PCB snaps into place, see Figure
3.
If the enclosure is present it is to be mounted on a vertical surface
using the four integrated mounting holes that facilitate a #10 screw
(not supplied) as shown in Figure 4.
Open the enclosure by pulling on the latch on the right side of the
enclosure, at the same time pull on the cover as illustrated in Figure 4.
Make wire connections as per the "Wiring" instructions on page 2.
Swing the door closed until latched. For added security, two screws
are provided that may be installed in the integrated screw tabs. See
Figure 5.
