Pt100 temperature sensor VFG54+ Basic RS485 Modbus

strap-onRS-485Modbus RTU

Contact sensor for temperature measurement (cold or hot water) on pipes and other curved surfaces. Spring-loaded brass contact sensor for a fast response. Models with a relay output for a 2-point controller or a 2-stage 2-point controller and color-changing LCD allow for a wide range of applications. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. • Application/type : Contact sensor • Purpose : Measure values • Measured values : temperature • Interface : RS485 Modbus • Configuration : BUS, DIP switches • Sensor : SI-Protection against permeation of humidity and mechanical stress (e.g. vibration) • Network technology : RS485 Modbus • Data transmission : bidirectional, RTU, half-duplex, baud rate 9.600, 19.200, 38.400 or 57.600, parity: none (2 stop bits), even or odd (1 stop bit) • Operating range temperature (°C) : -35..+120 • Operating ranges temperature (°C) : -35..+120 • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,5 K (typ. at 21 °C) • Power supply : 15..24 V = (±10%) SELV, 24 V ~ (±10%) SELV • Power consumption : max. 0,7 W (24 V =), 1,8 VA (24 V ~) • Material in touch with media : Sensor probe, brass, spring loaded sensor • Enclosure : USE-S, impact- and shock-resistant enclosure with quick-release cover, PC • Colour : pure white • Protection (IP) : IP65, according to EN 60529 • Connection : removable cable entry flextherm M20 for wire Ø=4,5..9 mm, removable plug-in terminal, max. 2,5 mm² • Mounting : along the pipe or sideways
