APPLICATION

The PD3221B module offers Digital and Analogue 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.

The module has four Digital I/O and two Digital Input channels. All Digital Outputs can work as source, sink or push-pull with current measurement. Three of the Outputs can additionally perform fast PWM output.

All Digital inputs can be configured as PNP or NPN. The inputs can perform Line Check functions.

This is useful with two-wire proximity switches. In case of error, the hardware will report either ‘Line open’ or ‘Line
short-circuited’ respectively.

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

The Digital Input channels 5 and 6 can additionally perform fast input functions.

The module has an analogue output current channel for 4-20 mA with source or sink.

The module has two analogue input channels for 4-20 mA current, 0-100 mV voltage or Pt100/Pt1000 temperature measurements.

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
