The OMB-DBK23 is a 24-line digital-input module that provides isolated digital inputs for OMEGA’s OMB-LOGBOOK and OMB-DAQBOARD-2000 Series data acquisition systems. The unit provides 500 V of channel-to-channel and 500 V of channel-to-system optical isolation, eliminating troublesome ground loops and protecting the data acquisition system from damage caused by accidental contact with high external voltages. Up to eight OMB-DBK23 modules can be connected to one system, for a total of 192 digital inputs.

Applications
The OMB-DBK23 can monitor a range of 3 to 30 Vdc inputs, making it especially suitable for applications such as process control or laboratory automation. The unit is capable of monitoring electrical devices such as proximity switches, thermostats and limit switches.
Connections
The OMB-DBK23 connects to a system’s digital I/O connectors and uses the digital I/O lines as a communications bus. Thus, the lines on a system’s digital I/O connectors are not user accessible when an OMB-DBK23 is in use. The OMB-DBK23 can be daisy-chained with other OMB-DBK digital I/O cards or modules via optional expansion cables. Signal connections to the OMB-DBK23 are made via screw terminals, which are conveniently located on its slide-out PC board.
Power
The OMB-DBK23 is equipped with an internal power supply and external AC adaptor. It can also be powered from an OMB-DBK30A battery/excitation module, a 12 Vdc car battery, or from any 9 to 24 Vdc source.
