Description
This Zelio Logic SR3 compact smart relay / programmable controller uses a supply voltage of 24V direct current. It has 26 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
- Packed with 16 discrete inputs and 10 robust relay outputs, this compact smart relay provides extensive point capacity for complex automation tasks. It allows industrial maintenance technicians and machine builders to consolidate multiple timers, counters, and control relays into a single, space-saving DIN-rail module, drastically reducing enclosure wiring and hardware footprints.
- Operating on a regulated 24V DC power input, this smart relay interfaces seamlessly with industry-standard control topologies and sensors while minimizing energy consumption. The 0-10V analog input capability enables direct integration with temperature transmitters, pressure sensors, and level transducers, providing a cost-effective alternative to full-scale PLCs for small-scale process control.
- This Zelio Logic module supports both traditional Ladder Logic (Ladders) for plant electricians familiar with schematic relays, and Function Block Diagram (FBD/SFC) programming for systems engineers managing advanced workflows. This flexibility simplifies the commissioning process and ensures that internal maintenance staff can quickly interpret, modify, and optimize code for automated conveyors, pumping stations, or packaging machinery.
