The BLX R100 series feedback unit allows for accurate position feedback where on-off indication (mechanical switches) or 4-20 mA Position transmitter or potentiometer is required. Feedback units can be factory or field mounted to the V100 Positioner with no additional parts or mounting brackets required, thus creating a very compact package.

Combinations of switches and transmitters or potentiometers are available. The corrosion resistant painting and sealing meet NEMA 4X as well as the sealing requirement IP66.

The hand adjustable cams offer slack free lock in place within 3° resolution and steep switching characteristics. R100 is furnished standard with two cable entries.
