Introducing the UCERB 08

Overview: UCERB 08 features

This user's guide contains all of the information you need to connect the UCERB 08 to your computer

and to the external devices you want to control. You can use the UCERB 08 in your control applications

to switch on and off a variety of devices, such as fans, blowers, pumps, etc.

The UCERB 08 is a USB 2.0 full-speed, electromechanical relay module. It is supported under

Microsoft

Windows

98 (2

edition), Windows ME, Windows 2000, and Windows XP.

The UCERB 08 provides eight single-pole double-throw (SPDT) Form C electromechanical relays. The

digital I/O lines on your USB module directly control the relays on your UCERB 08.

You connect your field wiring directly to the board's screw terminals. The screw terminals provide three

connections to each relay – normally open (NO), normally closed (NC), and common (C).

You configure the relay control logic polarity and the relay power-on state with on-board switches. The

relays are configurable as two banks of four. Switch settings can be read back with software.

The UCERB 08 is powered by an external 9 V, 1 A regulated power supply that is shipped with the

device. A USB cable is also included. Power OUT and USB OUT connectors let you power and control

multiple UCERB/ boards from one external power source and one USB port in a daisy

chain fashion. Depending on your load requirement, daisy chained boards may require a separate power

supply.

The UCERB 08 is shipped in a rugged enclosure that you can mount on a DIN rail or on a bench.
