Micro PLC PR-14 series (Expandable Range)series overview:

PR-14 range(Micro PLC) is advanced level model, incorporating a good mix of digital and Analogue IO, Integrated High Speed inputs and PWM output,clock with calendar, counters , timers , integrated keypad display, serial communications and an expansion port. Available in 120V/240VAC or 12V/24VDC versions ; Easy to configure with drag-and-drop function blocks using FREE xLogicSoft software. Program capacity has been enlarged to 512 function blocks as well, also high-speed count reaches 60KHZ.

PR-14 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-14 Series

◆70 ready-to use functions integrated-no additional devices such as operating hours counter required.
◆Extremely large program capacity:up to 512 functions possible.
◆10 digital inputs(incl 6AI with 12/24V DC)and 4 digital outputs on board.
◆Flexibly expandable up to 138DI,132DO,72AI,and 32AO.
◆Display of message texts,actual and set-point values and direct modification of the values on the display(not on pure variants).
◆Integrated data retentivity-ensures backup of the current values in the event of a power failure.
