DAT6000 Analogue Data Acquisition Interface Modules for PLC’s
Datexel, specializing in signal conditioning and Data Acquisitioning would like to present the DAT6000 Series of analog data acquisition interface modules for PLC’s
The DAT6000 series are an innovative way of connecting analog signals to digital PLC’s.
The DAT6000 modules condition, linearize, isolate, filter and convert the analog signals coming from various sensors in a high resolution digital signal. A few and simple instructions downloaded into PLC it is possible to acquire analog signals on only one digital input. The digital signal can be connected to any input of the PLC. The digital signal is composed of a series of 16 bits “word” containing the value of the analog inputs to acquire. The PLC controls the data transmission by a clock signal (CLK) generated from one of its output ports used to ask the device after the enabling of transmission by the enable signal (ENABLE). If the enable signal is high, at each rising edge of clock, the device will provide on the data line (DATA) one of the bit that composes the reading word. Every cycle of reading is composed of 1 synchronism bit and 16 bits for each analog signal; this means that every reading is composed of 33 bits. The rising edge of the ENABLE signal, managed from the controller, resets the cycle of reading and allows avoiding the reading of the unused input channels; the ENABLE signal can also be used to multiplex more devices to the same PLC's digital input.
The DAT6011 accepts two voltages (up to ± 1 V) or thermocouple signals.
The DAT 6012 accepts two signals coming from RTDs type Pt100, Pt1000, Ni100 and Ni1000, Resistance and Potentiometers.
The DAT 6013 accepts two signals coming from sensors with voltage output (up to ± 10 V) or current output (up to ± 20 mA).
The DAT 6021 accepts two thermocouple signals. The DAT6021 is Configurable input for ± 1 V or Thermocouples type J,K, R,S,B,E,T,N, and is Configurable by DIP-switch.
The DAT 6023-I accepts four current signals.
The DAT 6023-V accepts four voltage signals.
The 2000 Vac isolation between inputs, power supply and data lines eliminates the effects of all ground loops eventually existing and allows the use of the converter in heavy environmental conditions found in industrial applications. The DAT 6000 series is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
It is housed in a plastic enclosure of ½ Inch 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
