Elan has a variety of different signal converters. Most commonly, legacy controls with 4-20mA output signals aren't compatible with newer instrumentation and controls needing 0-15 and 0-20vdc powered inputs. So, Elan designed signal conditioners to bridge this gap. Simple and effective, we can create other converters as needed to suit your application. Give us a call, and we'll design the perfect signal converter for your application.
