Universal Input/Output (UIO) Motherboards

Signature Series Universal Input/Output Module Motherboards provide mounting

and wiring terminations for up to six Signature Series plug-in UIO (SIGA-“M” series)

modules. UIO motherboards snap into a rigid extruded track (included) with mount-

ing pads for convenient mounting into a variety of equipment enclosures. UIO

modules plug into the board and are held securely in place with captive machine

screws. All field wiring connects to terminal blocks on the motherboard, which

permits rapid removal and replacement of modules for troubleshooting.

The SIGA-UIO2R provides mounting and wiring terminations for up to two UIO

modules, and the SIGA-UIO6R provides mounting and wiring terminations for up to

six UIO modules. Both motherboards feature a riser #1 input and a riser #2 input

bus. Jumpers on riser #1 input (between modules), facilitate sharing a single riser

among more than one module. This significantly reduces wiring requirements.

Removing the jumpers pro-

vides separate riser inputs to each adjacent mod-

ule. Riser #2 input is fixed to each module position

and cannot be split.

The SIGA-UIO6 provides mounting and wiring termi-

nations for up to six UIO modules. This motherboard

provides two riser inputs that are common to all

modules.

UIO motherboards mount inside the MFC-A cabinet

or other suitable UL-listed electrical enclosure. Each

MFC-A will hold one UIO2R motherboard or one UIO6 or UIO6R motherboard complete with their full complement of

modules.
