Original product description
The SR-20ERA is a compact programmable smart controller for industrial and building automation tasks. It operates from a 12–24 VDC power supply and supports function block diagram (FBD) programming.
The controller provides eight digital inputs across terminals A0–A5 and B4–B5;the six A0–A5 channels can also receive 0–10 V analog signals. Four QA0–QA3 outputs use PNP transistor switching, with a stated output range of 0–24 VDC and output current of 2 A.
The controller supports up to 128 function blocks and has 64K of program storage. Its real-time clock has a stated backup duration of 80 hours at 25°C and maximum accuracy deviation of ±5 seconds per day. Listed operating temperature is -20°C to 70°C, while the storage and shipment range is -40°C to 70°C.
The enclosure protection rating is IP20. Expansion modules can be used to increase the available input and output points. The source also describes optional operation with voice and remote modules for be used between the controller and modules.
Applications stated in the source include machinery automation, flow control, building automation, and time-based control systems.
Before procurement, buyers should confirm the exact module configuration included in the quotation, terminal and wiring documentation, whether any expansion, voice, or remote modules are supplied separa load derating, required external protection, analog-input resolution and accuracy, programming software and cable requirements, communications interfaces, mounting details, and the suitability of the listed switching frequencies for the intended load.
Request current compliance documents if CE or RoHS evidence is required for the project.
