Analog Inputs
The Super Systems, Inc. Part Number 31611 Analog Board contains a group of three channels
isolated from the main DC power source. Each input is fully isolated. The board can be
connected to thermocouples, voltage sources from 20mV full scale to 1.28 Volts full scale,
voltage sources from 0 V full scale to 10 V DC full scale, or 4 – 20 mA current loops.
Adding a Jumper to an Input
When measuring a 4-20mA current signal or a voltage signal, such as a thermocouple, a jumper
must be placed on the corresponding two or three-position header. For example, Input 1 would
need to have a jumper placed between the pins labeled “I1” before connecting a 4-20mA signal.
Failure to add the jumper will result in damage to the circuit board. The jumper may already be
present at each of the three headers, but unless it is attached across both pins (not just one) it
will not be connected.
