DESCRIPTION

· The H3431 is a temperature and humidity regulator with RS485 output, designed for both outdoor and indoor use.

· It features a relative humidity and temperature probe on a 1-meter cable, capable of measuring and converting values to dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy.

· The device includes two relay outputs and three two-state inputs, supporting various signal types including dry contact, open collector, or two-state voltage signal.

FEATURES

· Temperature sensor with a range of -30 to +105 °C, accuracy of ±0.4 °C, and resolution of 0.1 °C.

· Humidity sensor with a range of 0 to 100 % RH, accuracy of ±2.5 % RH from 5 to 95 % at 23 °C, and resolution of 0.1% RH.

· Dew point measurement with a range of -60 to +80 °C, accuracy of ±1.5 °C at ambient temperature T <25 °C and RH >30 %, and resolution of 0.1 °C.

· Two relay outputs with a maximum voltage of 50 V, current of 2 A, and power of 60 VA.

· Three binary inputs with a minimum pulse duration of 500 ms, voltage across open contact < 3.3 V, low voltage level of 0 to +0.5 V, and high voltage level of +3.0 to +30 V.

APPLICATIONS

· Suitable for environmental monitoring and control in various settings, including HVAC systems, greenhouses, and industrial facilities.

· Ideal for applications requiring precise temperature and humidity regulation with additional data interpretation capabilities.

· Can be used in systems requiring binary input signals for monitoring or control purposes.
