DSP4TR 4 ch. relayboard 250V/16A, DIN Rail

The DSP4TR is a DMX512 controlled 2 channel mechanical relay and SSR switch pack for switching of high momentary inrush currents as expected with switching supplies.

The information of the power consumption of a switching supply doesn't says anything of its inrush currents strength which may rise up to the 50-70A.

The DSP4TR now is able to reduce these currents by switching at zero cross and using a precision timing between electronic and mechanical relays. Because of this feature the DSP4TR is able to switch on more ballasts at same time than normally at a 16A circuit breaker would be possible.

The DSP4TR has 4 volt free SPST switches for 250V~ and 16A rated current for DIN-Rail mounting in electrical installation cupboards.

There are two on/off switching hysteresis available.

All modes are adjustable via the three rotary code switches and the 4times DIP switch.

A very special of the DSP4TR is the 4 channel power on sequencer with delays from 1 to 99s, which is expandable by using further devices up to 32 channels
