Micro PLC PR-18 series (Expandable Range) series overview:
PR-18 range offers 4-line*16 characters LCD display and keypad for program modification or display and control whilst program is running.
An expansion port allows the connection of up to 16 expansion modules, extending the I/O channel count. Now it is also possible to use the analog output module to solve simple closed-loop control tasks.
Heating and cooling systems can be designed with the RTD PT100 module using special functions for PI control,ramp response and analog multiplexer.
Highlight of PR-18 Series
