Connection of ACI/DCI Solid State Relay board
The above diagrams show the types of solid state relay board's 4 channels, control connector and positive battery
terminal.
Each channel is controlled by one of the auxiliary switches on the ACI/DCI's handset, each has a current carrying
capacity of 20A.
The relays are solid state, they have no moving parts. When connecting the contact it can either be used to switch
the positive feed or be placed in the negative, but be sure that the negative (-ve) terminal is always ‘most’ negative.
If switching an inductive load, a coil motor or relay etc, then always install a diode across the coil.
The cable from the ACI/DCI unit with the 6-way connector, plugs into the connector on the relay board
Ensure all cabling is capable of carrying the currents concerned safely. Check connections are sound and correct.
Double check all connections prior to powering-up. Appropriately fuse all feeds from battery positive. If an accessory
requires only 12V, then where instructed above to connect a channel's common terminal to 24v, obviously that
terminal should be connected only to 12v (the centre point of the two batteries in a 24v system).
NB, The centre point should ALWAYS be permanently hard wired. NO SWITCHES OR CIRCUIT BREAKERS. The
power on/off for the model, and its fuse should ONLY EVER be in the POSITIVE battery wire as close to the battery
as possible.
