ADP15-DI Dual Current and Voltage Input Digital Indicator and Controller

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

The ADP15-DI 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-DI can be supplied with a wide range of different sensors from the LCM Systems range and can be combined with other instrumentation. Please consult the LCM technical department to discuss your application.
