The BLX R100 (positioner mounting) and the R300 (stand alone) feedback modules allow for accurate position feedback, where on-off indication (mechanical switches) or 4-20mA transmitter or potentiometer is required. Feedback unites can be factory or field mounted to the V100 positioner with no additional parts or mounting brackets required, thus creating a very compact package. Combination of switches and transmitters or potentiometer are available. The positioner/switch package is completely sealed, and can be fitted with a flat or raised indicator. Spring-loaded switches and transmitter make calibration simple and quick.
