Honeywell FC-HON32-23A32

Product Name:​ OneWireless™ Field Device Access Point (FDAP32) — Industrial Wireless Mesh Access Point
Product Introduction:​ Based on the available Honeywell product documentation, the FC-HON32-23A32 corresponds to the Honeywell OneWireless™ FDAP32 — an industrial meshing access point for ISA100™ Wireless (IEC 62734) and WirelessHART® (IEC 62591) field instruments. The FDAP32 is rated for hazardous plant environments (Class I, Div. 2 / Zone 2) and auto-discovers neighboring wireless devices to form a secure IEEE 802.15.4 mesh network.

  • AES 128-bit encryption with over-the-air and BLE-based authentication
  • Auto-discovery of neighboring FDAPs, ISA100 Wireless, and WirelessHART field instruments
Application Scenarios:​ Implementation of wireless field instrument networks in harsh, hazardous plant environments — including oil & gas production, chemical processing, refining, and utilities — where updating rates of less than 10 seconds are acceptable for critical monitoring or open-loop control. The FDAP32 supports up to 40 Enraf FlexLine radar gauges or Wireless Field Instruments.
Structural & Material Characteristics:​ The FDAP32 is housed in a ruggedized enclosure rated IP66/IP67 with G3 corrosion-resistant materials per ISA-S71.04. It features two external antenna ports for 2.4 GHz antennas, one 10/100 Mbps Ethernet port, and a grounding cable connection. The unit weighs 2 kg and measures 290 × 281 × 173 mm.
Working Principle:​ The FDAP32 operates as a mesh node in a OneWireless network. It communicates with ISA100 Wireless and WirelessHART field instruments over the 2.4 GHz ISM band using IEEE 802.15.4 radio links. Incoming wireless data is encrypted (AES 128-bit), authenticated, and forwarded via the 10/100 Mbps Ethernet port to the host system. The device auto-discovers neighbors and dynamically forms a self-healing mesh with up to 4 network hops.
Installation Requirements:
  • Mount in accordance with Class I, Div. 2 / Zone 2 hazardous-location regulations
  • Provide 18–30 VDC power (2 W) or PoE (5 W)
  • Connect both external antennas for antenna diversity
  • Ground the unit via the provided grounding cable
  • Ensure Ethernet cable routing complies with plant network infrastructure
  • Operating temperature range: -40 °C to +70 °C
Usage Notes:
  • The “23A32” suffix specifics (e.g., antenna configuration, regional certification package) were not individually detailed in the publicly retrieved Honeywell documentation; consult the official Honeywell OneWireless FDAP datasheet for the exact variant configuration.
  • Do NOT exceed 30 VDC input power
  • Maintain antenna clearance from metal obstructions for optimal RF propagation
  • Periodically verify mesh network health and neighbor tables
