GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM FLYING LEAD NETWORK TEMPERATURE SENSOR TNFL SERIES PRODUCT DESCRIPTION The single point flying lead network temperature sensor incorporates a precision sensor encapsulated in a 6 mm (0.236”) OD X 50 mm (2”), 304 series stainless steel probe. Standard wire length is 1.83 m (6’). All probes are constructed to provide excellent heat transfer, fast response and are potted to resist moisture penetration. The transmitter provides a BACnet® or Modbus signal for network connection. A compact ABS enclosure with a hinged and gasketed cover is provided for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. A typical application for the flying lead type probes is to monitor a single point temperature within the duct. Install the probe in a straight section of duct at a suitable distance downstream from any heating, cooling, or humidification devices. Drill a 3/8” hole in the top of the duct and hang the sensor in the air-stream. The enclosure provides mounting holes for ease of installation CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 ACCESSORIES - INCLUDED WITH E ENCLOSURE OPTION POWER SUPPLY BACnet®: 24 Vac/dc ±10% (non-isolated half-wave rectified) Modbus: 24 Vac/dc ±20% (non-isolated half-wave rectified) CONSUMPTION BACnet®: 25 mA max @ 24 Vdc Modbus: 10 mA max @ 24 Vdc OPERATING ENVIRONMENT -40 to 50°C (-40 to 122°F), 5 to 95 %RH non-condensing PROBE MATERIAL 304 series stainless steel PROBE SIZE 6 mm (0.236”) OD x 50mm (2”) L WIRE LENGTH 3.05m (10’) WIRE MATERIAL FT-6 rated plenum cable (22 AW) WIRING CONNECTIONS Screw terminal block (14 to 22 AWG) ENCLOSURE A: ABS, UL94-V0, IP65 (NEMA 4X) E: Same as A, with thread adapter (1/2” NPT to M16) and cable gland fitting COUNTRY OF ORIGIN Canada TEMPERATURE Sensing Element: NTC thermistor Accuracy: ±0.2°C (±0.36°F) @ 0 to 70°C (32 to 158°F) Probe Sensing Range: -40 to 60°C (-40 to 140°F) Resolution: 0.1°C/°F BACnet® COMMUNICATIONS INTERFACE Hardware: 2 wire RS-485 Software: Native BACnet® MS/TP protocol Baud Rate: 9600, 19200, 38400, 57600, 76800, or 115200 (auto-detect) Network Address Range: Locally set to 0-127 Serial Configuration: 8N1 MODBUS COMMUNICATIONS INTERFACE Hardware: 2 wire RS-485 Software: Native Modbus MS/TP protocol (RTU) Baud Rate: 9600, 19200, 38400, 57600, 76800, or 115200 (auto-detect) Network Address Range: Locally set to 1-255 (switch selectable) Parity: None Stop Bits: 1 Error Checking: A001 (CRC-16 reverse) INPUT VOLTAGE EFFECT Negligible over specified operating range PROTECTION CIRCUITRY Reverse voltage protected and transient protected SPECIFICATIONS 82.5 mm 3.25" 69.8 mm 2.75" 1/2” NPT 76.2 mm 3.00" 52.0 mm 2.05" 1.83 m 6.00’ 6.0 mm 0.236" 50 mm FT-6 Rated Plenum Cable, 22 AWG 304 Series S/S Probe
