Temperature and humidity sensor S15S-TH-MQ, 0...100 % RH, -40...+85°C, Modbus RTU, RS-485, M12

S15S-TH-MQ is a Banner temperature and humidity sensor in an overmolded M12 housing that reports relative humidity, temperature and dew point as Modbus RTU registers over RS-485. It ships with an aluminium grill filter cap.

• Accuracy: humidity ±2 % RH at 25 °C, ±3 % RH at 0...+70 °C and 10...90 % RH, ±7 % RH below 10 % or above 90 % RH; temperature ±0.8 °C (-40...0 °C), ±0.7 °C (0...+60 °C), ±1.3 °C (+60...+85 °C)
• Measuring range: humidity 0...100 % RH, resolution 0.1 % RH; temperature -40...+85 °C, resolution 0.1 °C; sample rate 3 s
• Output: RS-485, Modbus RTU, 9.6/19.2/38.4 kbaud, address 1...254
• Supply: 10...30 V DC, max. 50 mA; protected against reverse polarity
• Environment: IP65, IP67, IP68 at the M12 connection; operating -40...+70 °C, up to 90 % RH non-condensing
• Connection: integral 4-pin M12 male and female connectors

Baud rate, parity and address are set with the SNAP SIGNAL software through the BWA-UCT-900 USB adapter cable. An optional 10 µm sintered stainless steel filter is available separately.

Vibration per IEC 60068-2-6, shock per IEC 60068-2-27 (15 g, 11 ms). FCC Part 15 Class B, ICES-003(B).
