Analog Resistance Module
Product Description
This document describes the hardware installation procedures for the SC-ARES Analog Resistance Module.
The analog resistance module is an interface that accepts an analog signal input (voltage or current) and uses that signal to proportionally control a variable
resistance output. The device output simulates a 3 wire slide wire or rotary potentiometer. The resistive output is electrically isolated from the input control
signal.
The input signal type is DIP switch selectable to one of several factory calibrated standard ranges and the output has both ends of the potentiometer and
the wiper available on the terminal connectors. The output resistance simulates a potentiometer and does not wrap around at the end points.
The resistance module includes a regulated power output that can be used to power a current-loop transducer and also features a failsafe input that will
connect to the output terminals in case of power loss or for manual output control. There is also an LED power indicator and a manual override jumper for
failsafe operation.
The product comes with standard snap-track for easy mounting or is available with various resistance values. The potentiometer may be ordered with no
offset value such as 0-135 Ω, or may be configured with an offset resistance such as 20-30K Ω.
General Installation Requirements
For proper installation and subsequent operation of each device, pay special attention to the following recommendations:
-
Upon unpacking the product, inspect the contents of the carton for shipping damages. Do not install damaged device.
-
Avoid areas where corroding, deteriorating or explosive vapors, fumes or gases may be present.
-
Ensure that all equipment is installed according to local, regional, and national regulations.
Personal injury or loss of life may occur if you do not follow a procedure as specified.
Equipment damage or loss of data may occur if you do not follow a procedure as specified.
Take reasonable precautions to prevent electrostatic discharges to the controller when installing, servicing or operating
the controller. Discharge accumulated static electricity by touching one's hand to a well-grounded object before working
with the controller.
