APPLICATION

The PD3122 module offers 16 Digital I/O channels as interface for various types of process signals, valves, pumps, level detectors, actuators etc. and push-pull outputs for direct motor control. Each channel can operate as a Digital Output, Digital Input or Analogue Voltage Input.

The digital outputs can work as source, sink or push-pull with output current measurement.

Digital I/O channels 1, 2 and 3 can additionally perform fast PWM Output functions.

Digital inputs can be configured as PNP or NPN. The digital inputs can perform Line Check functions. This is useful with twowire proximity switches. In case of error, the hardware will report either ‘Line open’ or ‘Line short-circuited’ respectively.

All Digital inputs can measure analogue voltage 0-10 V.

Digital I/O channels 9 and 10 can additionally perform fast Digital Input functions.

All channels are overload and short-circuit protected. Notification can be enabled on any disconnection or process failure.

The device is programmable in COPP, which means that a part of, or a complete automation application can be downloaded and run in the module. The program can make use of ready-made components to control and monitor any process or machine application, both locally in the device but also via the network interacting with other devices.
