Senva AQ2W-BA2AABX Wall RH/Temp Sensor, BACnet/Modbus, No Display
Mounts on the wall surface over a junction box; a concealing ring covers oversized cutouts.
Communicates over BACnet MS/TP or Modbus RTU on 3-wire RS-485 (switch selectable).
Includes a solid-state relay (1A at 30 VAC/DC, NO or NC selectable) that can trip on an RH or temp setpoint, or air quality.
Needs 16-30 VDC or 24 VAC; one side of the transformer secondary is tied to signal common, so a dedicated transformer is recommended.
