Description

APPLICATION
The PD 640 is a general-purpose analogue I/O device with four I/O channels. Channel 1 and 2 may be configured for either input or output. Channel 3 and 4 are input channels. All 4 channels can be independently configured for either 0-20 mA or 4-20 mA signal types.  This enables most standard type analogue transmitters for pressure, temperature, flow, etc., to be connected to the input channels, and, for example, analogue actuators, motor controllers, etc, to be connected to the output channels of the device.

Conversion from or to 0/4–20 mA is performed directly in the I/O channels, which means that process variables are read or written in floating-point engineering units. For example, a process controller or a PC can read the process value from a pressure transmitter, which is connected to an input channel, in bar, kPa, psi, or any other engineering unit, depending on the configuration.

It is used with a BM 014 Base module.
