6 Digital Output Accessory

Connect the Digital Outputs
Loads are connected to the digital outputs by means of two 20-point removable
terminal blocks. The terminal blocks are provided as part of the output module.
Each of the terminal blocks consist of a fixed (header) part, and a removable (plug)
part. The screws at either end of the terminal block can be backed out to release
the terminal plug for ease of connection. The terminals support wire sizes from
AWG 24 to AWG 14.
Before using the digital outputs it is necessary to connect your load(s) and a (user
supplied) external DC power supply. The DC power supply is used to energize the
loads.
1. Connect the two leads of the DC power supply (in the range of 10 to 50
volts DC) to the terminals labeled +VDC and DC COM.
2. Connect the positive output of the supply to either or both of the +VDC
terminals, they are internally connected.
3. Connect the common connection of the power supply to either or both of
the DC COM terminals, they are internally connected.
The locations of the terminals of the digital output accessory are shown in the
terminal diagram below.
You can connect loads to as few as 1, or to as many as 36 of the outputs. Each load
must fall within the range given in the output specifications table. The terminal
diagram above shows the relationship between the output terminals and the special
function keys of the 1200W keypad.
The digital outputs source current to connected loads. The positive terminal of a
polarized load should be connected to the output terminal. The negative terminal
of the load should be connected to the DC common connection of the power
supply.
