Solid State Outputs - Deep Sea Electronics Plc 701 Operating Instructions Manual

5 SOLID STATE OUTPUTS

DSE's utilisation of Solid State Outputs gives many advantages, the main points being:
♦ No Moving Parts
♦ Fully Overload / Short Circuit Protected.
♦ Smaller dimensions hence lighter, thinner and cheaper than conventional relays.
♦ Less power required making them far more reliable.
The main difference from conventional outputs is that solid state outputs switch to negative (–ve)
when active. This type of output is normally used with an automotive or plug in relay.
