RTD to Digital PLC Input Module.
Obsolete Product.

The DATEXEL DAT6012 Converts RTD's, Resistance and Potentiometers in to a digital signal that can be read by a digital PLC. The RTD's that the DAT6012 can accept is Pt100, Pt1000, Ni100, Ni1000.

The DATEXEL DAT6000 series amplifies, linearizes, Isolator, filters and converts the analog signals to a high resolution digital signal, by few and simple instructions downloaded into any PLC. It is possible to acquire more analog signals on one digital input.
The DAT6012 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 bits that composes the reading word.
Every cycle of reading is composed of 1 synchronism bit and 16bits 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 to avoid the reading of the unused input channels; the ENABLE signal can be used also to multiplex more devices to the same PLC's digital input.
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 DAT6023-V is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DATEXEL DAT6000 series is housed in a plastic enclosure of 12.5mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
