Overview
The Celesco RT8420-0R50-211-1220 is a precision 4-20mA rotational position transducer engineered for demanding industrial automation applications. This model provides extended rotational position feedback from as little as 1/8 of a turn full-scale all the way up to 200 turns full-scale. With a resolution of 0.08893mA per degree, this transducer delivers reliable position measurement for motion control systems, valve actuators, process automation, and equipment monitoring across manufacturing, automotive, and energy sectors.
Key Features
- 4-20mA Output Signal: Industry-standard analog current loop compatible with most PLC inputs and industrial controllers.
- Extended Range Capability: Combines superb linearity and resolution of a plastic-hybrid potentiometer with the durability of Celesco’s 4-20mA circuit to provide accurate and reliable electrical signal over all ranges.
- Adjustable Zero & Span: Fully accessible zero and span settings allow precise matching of the output signal to the required measurement.
- Harsh Environment Rated: Designed to meet tough NEMA 4 and IP65 standards for harsh industrial environments.
- Reversible Output: Output signal direction can be reversed at any time by simply changing the dip-switch settings found on the internal signal board.
