Connect as per connection diagram in rear in manual.
6.8.4
Digital IO Section
Refer to drawings at the rear of this manual for this item.
The DIO section provides general-purpose inputs and output capable of sensing the state of 8
switch inputs and controlling 8 relay outputs. Connection is via plug-in Mini Combicon (R)
screw terminals. The DIO section is very versatile and reference should be made to the
installation drawings for details.
The digital section features LED indicators for input and output status. If the digital section
detects an input signal (voltage) the corresponding LED will be illuminated. If an output LED
is on then the given output relay is closed.
6.8.4.1
I/O Connections
Refer to drawings at the rear of this manual for this item.
6.8.4.2
Inputs
Refer to RCI-1550 User Wiring Detail – DIO2.
The DIO section contains 8 isolated inputs that require an external voltage source to activate.
This means that each input has two connections, a positive and a negative. This allows the
digital section to sense either switched high or switch low signals. To sense a switched low
signal, as would come from a switch with one side grounded, the output of the switch is
connected to the negative of the desired input and the positive side of the input is tied to the
supply. For a switched high signal as would come from a switch connected to the supply, take
the switch output to the positive of the desired input channel and ground the negative side.
The DIO also contains a dedicated ATB input. This only requires a simple switch closure
between the two associated pin. No voltage is require to be applied to this input
Finally the DIO section has a disable input which forces the outputs to a predefined state.
This input has the same properties as the eight data inputs.
The function of the switch inputs is defined in software and reference should be made to the
software configuration sheets for details.
