APPLICATION
PD 644 is a device in the M36 series with analogue channels.
The device offers 6 channels as interface for various types of transmitters with signal output in the range 4-20 mA.
Four channels support HART communication for up to 5 HART transmitters on each current loop.
Two of the channels can be configured for analogue output signals in the range 4-20 mA.
Four channels support HART communication for up to 5 HART transmitters on each current loop.
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.
PD 644 is used with the BM 005 base module.
All channels are protected against overload and short circuit to both negative and positive supply voltage and notification can be enabled on any disconnection or process failure.
