PDW90-FN Point-to-Multipoint Wireless Process Signal Field Unit
Brand: Precision Digital Corporation
PDW90 field units transmit analog, digital, and Modbus® inputs from any location in the field to the PDW90 base station.
Just set the network ID and Modbus address and put the field unit wherever there is a 24 VDC power and a process signal.
Once it has been connected to the base station, it will transmit all signal connections wirelessly.
