Specifications: Parameter Specification Product Range Harmony / Zelio Logic (Smart Relays - SR2 Series) Device Type Compact Smart Relay (Micro PLC with basic integrated interface) Power Supply 100-240V AC, 50/60 Hz (Universal AC supply, as indicated by the "FU" suffix). Built-in Digital Inputs 6 inputs (Typically 24V DC compatible). Built-in Relay Outputs 4 outputs (Relay contacts, likely SPDT/changeover type). Output Contact Rating Typically 8 A @ 250V AC (resistive load). User Interface Integrated basic display (e.g., 2-line text LCD) and navigation buttons for simple programming, monitoring, and parameter setting. Programming Method Directly via the front-panel interface or via PC software (EcoStruxure Machine Expert - Basic, formerly Zelio Soft). Expansion Capability None (This is a compact, non-expandable model). Communication May include a basic communication port (e.g., RS-485 for Modbus) for simple networking. Advanced communication requires optional modules. Program Memory Sufficient for basic to moderate ladder logic programs. Real-Time Clock Often included for time-based functions. Mounting DIN Rail (35mm) Operating Temperature -20°C to +55°C (typical) Standards & Approvals UL 508, CSA, IEC/EN 61131-2, CE, RoHS.
