Programmable Logic Controller Pixsys Electronics TCT500


Programmable logic controller TCT500 is the ideal solution to integrate control and supervisory functions in a single device. Main data can be visualized on the 7-digits display for the monitoring of selected values. Four analog universal inputs are available for linear signals 0…1V, 0…10V, 0…20mV, 0…20mA, 4…20mA (10 or 16bit) and temperature sensors PT100, NI100, TC K, J, S, T, R, E (16bit).

A 10-12V tension is also available for potentiometer inputs or sensors supply, as well as a stabilized 10V tension for load cells and 6 additional digital inputs PNP/NPN. It is possible to control two bidirectional encoders (12KHz each or 25KHz if single input) by means of dedicated functions included in the development environment Plprog. Five digital outputs (relay 5A - resistive), one logic output 12V for SSR and 2 outputs 0…10V are available. Main hardware features include back-up battery,real-time clock and serial communication RS232/485 (optoisolated) on pin. Protocol is ModBus-RTU or Open protocol for communication with other devices. The development environment PLProg is based on the drawing of a Ladder diagram and it is divided into user-friendly function blocks. Besides standard functions like counting, timing, PID control loops (with integrated algorithm) other available options include mathematical formulas, motion control, check on bit and modules for the mangement of serial ports with configuration Master, Slave and Multimaster. Supply 12..24Vac/Vdc does not require external power supplier. This compact and powerful device assures high flexibility and cost-effectiveness, therefore offering an excellent solution for application with small-medium I/O number.
