How are the Plug-In relays installed on the D8112 Control Communicator?
The Plug-In relays are inserted into the DIP (Dual IN-line Pin) sockets located on the board to enable various functions of the D8112 Control Communicator. Only three (3) relays can be installed simultaneously. Each D136 plug-in relay has two legs on one side and three legs on the other side. When inserting the relays, always ensure that the three leg side is to the left and the two leg side is to the right. Incorrect insertion will not damage the relay or the D8112, however the related circuit will not function.
