xzriza Electro-magnetic Encoders Model TRE 42 Model TRE 42: Synchronous Serial Interface - 12 Function The absolute angle information derived by the encoder is converted into serial information by an internal parallel-serial converter and then transmitted to a receiving electronic circuit in synchronism with a clock. Important advantages are : Low number of data lines and high reliability. Maximum data transmission rate The date rate ist defined by the following factors: □ Clock frequency 1 MHz max up to 40 meters connection line □ Delay time of the overall electronics (between 40 and 150...

Electro-magnetic Encoders Model TRA 42 Model TRA 42: Analogue outputs 0-20 mA, 4-20 mA, 0-10 VDC or ±10 VDC, Function The contactless electromagnetic sensor system is extended with a 12-bit D/A converter so that the measured variable is available as an analogue signal from 0 (4) to 20 mA, 0 to 10 V or ± 10 VDC. Measuring range setting The rotary encoder has a maximum measuring range of 1,474,560° (4096 revolutions). As standard, the measuring range is set to 3600°, i.e. 10 revolutions. Pre-set measuring ranges which deviate from the standard can be ordered. To do this, the desired measuring...

Electro-magnetic Encoders Model TRA 42 Functional description and adjustment modes The following parameters can be adjusted by the user in situ: Code sense, zero point, end point, preset value and default values, via the multi-functional entries MFP 0 and 1 (entry circuit E1). Before delivery the measuring range will be set at 0 to 3600 degree and the code sense increasing CW with view to the shaft end. The default value for the Preset value is the centre of the measuring range. Other values can be realized ex-work. The encoder will be supplied ex work with the default values. Table for...
