I.O. Connections (J1, J4)
The DCB-274 has a robust set of input and output signals. Two connectors (J1 and J4) provide dedicated
inputs and outputs. Five user-defined signals are also provided. All inputs can withstand voltages in
excess of +28 volts. Two high-voltage, high-current outputs are available to drive solenoids, relays, motors,
etc.
Fourteen input signals can be configured as either sourcing or “PLC” inputs. Thus, many
controllers/sensors that provide “true” outputs are easily adaptable.
