ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC SR2E121B - Smart Logic Relay
The SCHNEIDER ELECTRIC SR2E121B is a compact, monobloc smart logic relay from the Zelio Logic SR2 series, designed for decentralized control of small automation systems. This programmable logic controller integrates a 12V DC power supply, 8 digital inputs, and 4 relay outputs, facilitating direct control of actuators in applications requiring sequential or combinational logic. Programming is executed via Ladder Diagram (LD) or Function Block Diagram (FBD) using Zelio Soft 2 software, making it suitable for standalone machine control, building automation, and HVAC systems.
