DMX512 controlled 96 channel open collector driver

model: DMX96OC-EXTPS and DMX96OC
technical data sheet

The DMX96OC-EXTPS decodes 96 consecutive DMX512 channels to open collector NPN outputs. The starting address is selected by an easy to read (and set) three digit thumbwheel switch. The switch is mounted on the front panel along with indicators for power, signal, and an output 1 mimic. The DMX in, DMX through, and four female DB-25 output connectors are located on the back panel. All connectors feature gold plated contacts. The DMX512 input is optically isolated from the outputs and is protected against miswiring up to 120 volts. Power connection to the DMX96OC-EXTPS is made via a three position external barrier terminal strip. The end user's 12 - 24 volt DC power supply is connected to the positive and negative terminal position. An additional "output common" terminal block connection is available for high current applications.

Each output of the DMX96OC is capable of sinking 100mA. Higher current may be possible based on duty cycle and other constraints. Contact Doug Fleenor Design for engineering assistance.
