Field Wireless Multi-Protocol Module FN310 with "Field Wireless Communication Module FN120" is connectable with a field wireless network as a field wireless device. This product acquires sensor data from a connected sensor and transmits it to a field wireless network through FN120. Refer to General Specifications of FN120 for an overview and detailed information.
Features
Protocol conversion :
This product can convert the wired communication protocol to the ISA100 Wireless protocol, and transmit it to the field wireless network. ISA100 Wireless is an international, industrial wireless networking standard engineered to serve the needs of process industries.
Multi-protocol support :
HART *1 or Modbus *2 communication protocol can be selected. Various wired legacy device required by plant operation can be converted into a wireless device as required.
*1: Protocol code: J： Digital communication (HART 7)
*2: Protocol code: M： Digital communication (RS485 Modbus Protocol)
Installation flexibility :
With built-in batteries, this product can supply power to the connected field device, eliminating the need for cables.Cable elimination allows installing a device at locations where it was previously either inaccessible or cost-prohibitive because of cable management and cost.
Small and lightweight housing with LCD :
This product has a small and lightweight housing with a built-in LCD that displays the process data and communication status.
