Introduction
The DAT6000 series is an evolution in the connection techniques of the analog
signals to the PLC.
The devices of this serie performs many functions as: amplification, linearization,
isolation, filtering and conversion of analog signals, coming from various sensors,
in a high resolution digital signal. The digital signal is transfered to the PLC by
a bus connected to any one of the controller’s digital input. It is composed by a
series of 16-bit ‘words’ containing the values of the analog signals to be
measured. The transfer is PLC controlled by a clock signal coming from one of
its output ports. At every clock pulse a bit of the data is transmitted.
Using few and simple instructions the PLC is even capable to acquire more
analog signal on a single digital input.
The devices are also provided of an Enable signal which, handled by the
controller, allows to " multiplexing " many devices on the same digital input.
The DAT6000 series is composed of the following devices:
Device Channels Input Type
DAT 6011 2 mV and Tc
DAT 6012 2 RTD, Res. and Pot.
DAT 6013 2 V and mA
DAT 6021 4 mV and Tc
DAT 6023 4 V or mA
