  • PR-12DC-DA-R


PR-12 Series highlights at a glance:
Customizable Start-up page / screen 
4-line, 16-character configurable backlight display 
Modify parameters via Keypad panel without downloading new program
Various blocks’ different parameters can be displayed on one screen / page simultaneously
Randomly specify a specific page to display the IO status of the CPU
Alarm page can record and display the exact alarm occurrence time 
Programmable up to 64 (user defined) screens / pages 
Modbus RTU &ASCII protocol supported. 
Unit Size allows for DIN-rail mounting together with commonly used breakers in building automation applications
Retentive memory capability standard feature on the PR-12 model. 
It’s optional for xLogic to act as slave or master in Modbus RTU communication network.
Extra large program capacity (512 function blocks available)  
The ideal solution for simple automation tasks 
Minimizes costs - replaces many conventional switching control devices, 
Reduces time requirements – simplified wiring and panel layout, 
Saves much space in the switching cabinet - modules based on a 4 width industry standard dimension replace a wide variety of relays, timer switches and contactor relays 
Furnishes the widest range of capabilities and successful implementation of extensive applications with the option of selecting from 69 integrated functions and linking up to 256 of them in the user program. 
Operator control and monitoring are made very user-friendly by means of a 4 line, 16 characters per line, backlight display.
Additional external text display extends the possibilities for operator control and monitoring 
Password protection – Protects your engineering IP 
69 integrated, pre-tested functions – No additional devices, such as elapsed time counter, are required 
Linking of 512 functions is possible – Extensive applications can be implemented without restrictions 
Eight digital inputs (incl. four AIs at 12 / 24 V DC) and four digital outputs on board 
Display of message texts, action items and current values as well as direct modification of the values on the display 
Retentive data memory – Protects current values against loss in the event of a power failure
Together with the xLogicSoft software, configuring of the xLogic is simply intuitive: program generation, project simulation and documentation are accomplished using drag and drop functionality, allowing maximum ease of operation.
