Ground terminals
Three input ground terminals are located next to the input terminals. Up to two
wires, size 12
–
22 AWG, can be clamped into each ground terminal. If more than
two wires must be joined at a common point, use an external terminal strip to
accommodate the additional wires.
Connecting outputs
All eight outputs are universal and can be configured by software to operate
either analog or digital devices. Connect the device under control between the
output terminal and one of the ground (G) terminals on the same bank.
Override cards
For large relays or devices that cannot be powered directly from a standard
output, install an output override card. Override cards provide:
◆
A wide choice of output signals.
◆
A slide switch for automatic or manual control.
◆
An LED for assessment of the output state.
Install the output override cards in the area under the plastic cover next to the
output terminals. The following output cards are available from KMC Controls.
Grounds and Switched Commons
When using an output override card, use the
SC
terminal instead of the ground
(G) terminal as signal common. Use the
SC
terminal in the same output bank as
the output terminal.
