Air-Eagle SR Plus Contact Input Transmitters by BWI Eagle remotely control equipment using an external relay or switch inputs. Single or multi-channel industrial wireless remote control units can operate one or more receivers up to 600 feet. Contact input transmitters include a terminal strip that accepts one, four, eight or 20 dry contact inputs from any external relay or switch.
They are commonly used in applications requiring automatic activation upon contact closure. Lid-mounted pushbuttons can be added for manual activation. These stationary units are powered by 100-250VAC, 9-36VDC or internal 3VDC batteries.
Our systems offer a cost-effective solution in applications where running electrical cables is impractical, impossible or too expensive. To see product options, view the Contact Input Transmitter Product Guide.
