One Unit Does It All! Current, Voltage, Input or Output, Increased, Decreased or Reversed.

One major problem in installing new products in existing buildings is signal compatibility. Older systems have many oddball ranges that don’t work with all the neat stuff we sell today. One answer is to replace all the old system components. Another, more economical, suggestion is to use signal conditioning devices.

The USA420 can take any selected input in the 0-35Vdc or 0-44mA ranges and convert it to your required electronic output. It can increase, decrease or reverse a signal. You can adjust the start point and span. This is the most flexible device to stock for anyone doing building automation retrofit. 20Vdc, 30mA output included for powering external devices.
