Description

This Zelio Logic SR2 compact smart relay / programmable controller uses a supply voltage of 24V direct current. It has 20 inputs / outputs with screw-clamp terminals. It has compact design, allowing installation on DIN rail. It also offers simple programming, display and diagnosing of malfunctions display and navigation buttons. Its simple ladder programming makes it adapted for non-specialists.

Features

Outfitted with 12 discrete inputs and 8 robust relay outputs, this compact controller allows industrial automation technicians to consolidate multiple mechanical timers, counters, and auxiliary relays into a single module. This localized density slashes installation footprints and drastically simplifies panel point-to-point wiring in machine automation and HVAC controls.
Out of the 12 inputs, 6 can be programmed as 0 10V or 0 24V analog input channels, allowing for direct connection to temperature probes, pressure transducers, and humidity sensors without purchasing expensive expansion cards. This built-in flexibility eliminates comparison confusion by giving your PLC system instant, cost-effective instrumentation feedback.
This module supports both traditional Ladder Diagram (LD) syntax for up to 240 rungs and Function Block Diagram (FBD) visual scripting for up to 500 blocks. This dual compatibility empowers software developers and field electricians alike to comfortably configure custom automation logic, run rapid real-time PC simulations, and reduce commissioning time.
Equipped with an internal real-time clock backed by a 10-year battery reserve, the relay handles automated time-delay actions, shift-based facility scheduling, and weekend energy-saving routines with zero drift concerns. This reliable autonomous time tracking safeguards operations against power outages, ensuring your automated systems restart seamlessly on schedule.
