Input and Output Connection

Analogue / Digital Inputs

The UIG-2 has 4 inputs that can be individually 
configured for either analogue or digital 
operation.

Opto-isolated Digital Inputs

The unit has four opto-isolated digital inputs.

These inputs offer greater electrical protection 
than the analogue/digital inputs, but can only 
be used in digital mode.

The opto-isolation also offers better electrical 
noise rejection for those installations where 
this could be a problem.

To use these inputs, an external supply is 
required, connected to the 12Vin pin. 

0VOpto is provided as a landing connection for 
convenience. An LED gives visual indication 
when a supply is connected across 12Vin and 
0Vopto.

Instead of an external supply, the 50mA 
current limited 12Vout supply can be used, 
however this will bypass the optical isolation. 
To use this supply, connect 12Vout to 12Vin 
and 0V to 0Vopto at the connector.

Switch closure is made between the input and 
0Vopto. Wire distance from the device to the 
UIG-2 should not exceed 10m (32 feet).

The function of each input is programmable 
with iCANsoft.

Analogue Mode

In analogue mode, the inputs have a voltage 
range of 0V to 10V. The input device is 
connected across the appropriate input and the 
0V reference. Wire distance from the device to 
the UIG-2 should not exceed 10m 32 feet).

50mA current limited, regulated voltage 
sources of 5V and 12V are also available at the 
connector for devices such as variable resistors 
without the need for an external supply.

Should the power supply to the UIG-2 be 
below 12V, then the 12V source will follow the 
UIG-2 supply voltage.

Digital Mode

In digital mode, switches can be connected 
between the appropriate input and 0V.
The input functions can be programmed to 
operate on both a switch closure and release.
