Programmable Relay PR-12 Series (Economic Range) Overview

Economy PR-12 range is the entry level model of xLogic Micro PLC family,  able to process up to 64

function blocks in a single program,  also is the perfect maintenance product, and yet can adequately

control a new process from the start. Economy PR-12 Series is capable of replacing many of the discrete

components(such as multiple timers, relays, contactors and counters etc) used in conventional systems,

opening up a whole new range of possibilities for economical simple control solutions. Economy

PR-12 Series exclude expansion feature , NO keypad panel , NO PWM output & High Speed pulse

counting capabilities, but analog inputs also are available, clock with calendar, counters , timers, and

available in 120/240VAC or 12V/24VDC versions,Easy to configure with drag-and-drop function blocksusing FREE xLogicSoft software.
