Description

On-wall- humidity- and temperature sensors HYGRASGARD® AFTF - Modbus - T3
W-Modbus is a wireless-based further development of the proven Modbus standard for the wireless connection of Modbus-enabled sensors, controllers and devices. W-Modbus devices communicate via a wireless radio link from LumenRadio - independently of the in-house Wi-Fi and without leaving the proven protocol standards. Thanks to the reliable and interference-resistant wireless network, entire buildings can be networked and the majority of Modbus RTU cables can be replaced.
Innovative Modbus sensor with galvanically separated RS485-Modbus-interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in curent-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated; with customised programming in the 7-segment and dot-matrix range). The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
