Assembly and Disassembly of UMC100.3 and IO Modules

You can attach the UMC100.3 and the IO modules as follows:
• Snap-on mounting onto a 35 mm standard mounting rail, without tools (UMC100.3 and IO devices)
• Mounting via screws on a mounting plate (UMC100.3 only)

Supplying the UMC and IO Modules

If 24 V DC is available use the UMC100.3 DC type and connect both the UMC100.3 and the IO modules to the 24 V DC supply.
If 110-240 V AC/DC is available use the UMC100.3 UC. The UMC100.3 UC provides a 24 V DC supply output. This output is intened to
supply the IO modules and digital inputs with 24 V DC. It is not intended to supply contactor coils.
The UMC100.3 UC supply output is limited to 250 mA for an environmental temperature of 60 °C and to 450 mA at
50 °C. The total current consumption of the connected IO modules, transistor output DO3 and communication
interface must not exceed that limit. Details about the current consumption of the IO modules and caluculation
examplesare available in section "Technical Data".

Connecting the IO Modules DX111-FBP.0 and DX122-FBP.0

The modules DX111-FBP.0 and DX122-FBP.0 increase the number of inputs and outputs provided by the UMC100.3. The
UMC100.3 can be expanded with one digital IO module. Thus, 8 additional binary inputs, four additional relay outputs and one
analogue output for driving an analogue indicator instrument are available. The IO modules are connected via terminals Ca
and Cb (see below) to the UMC100.3. Because of limited installation space it might be desirable to mount the IO modules se-
parately from the UMC100.3. This can be carried out without any problems as long as the maximum cable length is not excee-
ded.
The following limits apply when connecting an IO module:
• Either the DX111-FBP.0 or DX122-FBP.0 can be connected. It is not possible to connect both of them to the UMC100.3.
• The distance between the UMC100.3 and the IO modules must not be longer than 3 m.
