ADP15 Potentiometer Input Digital Indicator and Controller

The ADP15-POTENTIOMETER range of products is very versatile, accepting a wide range of different signal input types and ranges.

The ADP15-POTENTIOMETER's flexibility makes it the first choice for many control system designers. Supporting products like PC software, printers, and sensors, means most customers can deal with a single supplier.

Outputs include:-

Analogue voltage and current, Industry standard digital communications, Relays, Printer Drive

Options and Accessories include:

Panel mounting via DIN rail mounting
Power supplies for 110/230 V AC or 9-32V DC
Communications for Printer, PLC or PC

The ADP15-POTENTIOMETER can be supplied as part of a system, and will interface directly with LCM Systems potentiometric sensors, including the PD13. Please contact our technical department to discuss your application.
