The DINTAP is a DIN-Rail mounted DMX512 optical isolator. The output is electrically isolated from the input by a 750V DC to DC converter and a 2500V 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.
All specifications meet or exceed DMX512 requirements
