The SINEAX B812 unit supplies all commercially available 2-wire field transmitters.

The B812 unit supplies 2-wire transmitters and provides the 4 - 20 mA signal galvanicly separated at the output. The separation is HART penetrable, i.e. you can parameterise or read out intelligent transmitters via HART or customised protocols. Two power supply versions with wide area power packs ensure the connection to all common power supplies.

 It is one of the smallest products on the market. Nevertheless, we did not make any compromise in relation to safety. The unit embodies galvanic isolation between all circuits and complies with the whole range of EN 61 010 or IEC 1010 requirements. The intrinsically safe design connects to all field instruments in explosive gas or dust atmospheres (Zones 0, 1, 2 or 20, 21, 22).

• Patented contactless capacitive system, wear-free
• Measuring range, direction of rotation, characteristics, output changeover and other functions can be programmed via PC: facilitates planning and project work, short lead times, minimal inventory
• Angle of rotation measuring range: 0°...10° to 0°...50° or 0°...50° to 0°...350°
  With gearbox 0...20° to 0...1555 revolutions
  Measurement output (measuring/supply circuit) utilizes 2-wire connection (4 to 20 mA signal)
• Simulation of measured value allows to test subsequent control circuits, control loops or measuring circuits during installation
• Display of present measurands and graphical representation on screen for longer time periods
  Adjustment of mechanical position and fine adjustment of the analog output, zero point and span may be set independently
• Programmable output characteristics: linear, V-characteristic or freely selectable linearization curve
• Shaft can be turned through full, no damage occurs even if the upper limit value of the measuring range is exceeded
• Serial interface
• Permissible static load on the shaft: max. 1000 N (radial), max. 500 N (axial)
• Surface mounting device in rugged housing (IP67): vibration and shock resistant
