6 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.
TYPICAL CONNECTIONS
Solid state output from DSE module
eg. Terminal 3 of 703/4 - FUEL
* Observe polarity when using
relays fitted with integral diodes!

NOTE:- The Close Mains Relay should be NORMALLY CLOSED when de-energised for fail
safe reasons. Should the DC supply fail the mains will always be available. The output from the
DSE solid state output when energised will OPEN the relay therefore isolating the mains supply.
