Motor Driver (DC / Position Proportional Converter) RN748A The RN748A is a signal converter that receives a 4-20 mAdc input signal from a controller and outputs a relay contact signal to drive a control motor with a built-in feedback potentiometer for position proportioning operation. Also, by setting the center of the angle of rotation and the proportional band for the input signal, split operation is possible. Specifications Input Model No. configuration Ex.: RN748A0000 Basic model No. External dimensions (Unit: mm) Optional parts (sold separately) Name Sample settings for center of angle of rotation and proportional band 1. Center of angle of rotation: 50% (12 mA) Proportional band: 100% (16 mA) 2. Center of angle of rotation: 25% (8 mA) Proportional band: 50% (8 mA) 3. Center of angle of rotation: 75% (16 mA) Proportional band: 50% (8 mA) Direct action (opening direction on input increase) Reverse action (closing direction on input increase)
