Rievtech Micro PLC Economic Type Programmable Relay PR-12DC-DA-R-E Mini PLC with Non-expandable
Product Description
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.
