APPLICATION

PD 820 is a device in the M100 series with digital I/O channels. The device offers 15 channels as interface for various types of process signals, valves, pumps, level detectors, actuators etc. and push-pull outputs for direct motor control.

The 15 channels consist of:
– 15 digital inputs/outputs, whereof one channel can operate as fast digital input.

Digital inputs can be configured to perform Line Check.
The Line Check function can be used in relation to two-wire proximity switches. In case of error the hardware will report either ‘Line open’ or ‘Line short-circuited’ respectively.

The device is programmable in COPP, which means that a part of, or complete automation application can be built and downloaded by the user. 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.

All output channels can source a positive voltage to external loads relative to the common negative supply voltage, or can sink current from the load to ground.

All channels are protected against overload and short-circuit and notification can be enabled on any disconnection or process failure. The supply current for the device must be limited (with a fuse). The total current for all outputs on the device is limited to 5 A.

The PD 820 can be used with the BM 104 base module.

PD 820 can alternatively be used with the BM 105 base module that also provides a separate terminal block for connections to relays. This will enable the PD 820 to use 9 digital inputs/outputs and 6 individual potential free relay outputs.

The device can be fixed to the base module by means of a screw.
