The Edwards SIGA-UIO6R Universal Module Motherboards provide mounting and wiring terminations for up to six Signature Series plug-in UIO (SIGA-“M” series) modules. UIO motherboards slide into a rigid extruded track (included) with mounting 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 Edwards SIGA-UIO6R Universal Module 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. Of course, removing the jumpers provides separate riser inputs to each adjacent module.

A wide assortment of multi-function plug-in modules provides total flexibility. Integral jumpers between modules allow the sharing of risers to reduce installation wiring. On-board modules make decisions and input an alarm from initiating devices connected to them even if the loop controller’s polling interrogation stops. The module’s automatic self-diagnosis identifies when it is defective and causes a troubling message. The user-friendly maintenance program shows the current state of each module and other pertinent messages. This results in substantially improved control panel response time and less sensitivity to line noise and loop wiring properties.

Signature Series Universal Input/Output Module Boards are compatible only with SIGA-“M” Series I/O Modules, which require a Signature Data Controller.
