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. |
