Product Description
Doug Fleenor Design DINTAP DIN Rail Mount DMX Isolator
The DINTAP is a DIN-rail mounted DMX512 optical isolator. The output is electrically isolated from the input by a 750 volt DC to DC converter and a 2500 volt optical isolator. The DINTAP allows the DMX signal to be split without the possibility of reflections from one signal path interfering with the signal to a device on a different path. By isolating the output, electrical noise and hazardous voltages on the output are prevented from affecting (or damaging) devices on the input. Other DIN-rail mounted interfaces are available with a single dry contact relay closure or open collector optical coupler. Interfaces such as 0-10V analog and RS-232 may be manufactured on a custom basis.
