E+E Elektronik HTS201 Room Sensor for Relative Humidity and Temperature
Hazardous location E+E Elektronik HTS201 Room Sensor for Relative Humidity and Temperature delivers precise and reliable measurements of relative humidity (RH) and temperature (T) in residential and commercial building automation. Its patented sensor technology ensures outstanding measurement performance, resilient even in dusty environments. The innovative enclosure prevents false air ingress and minimizes self-heating.
This device provides RH and T data through two analog outputs or via the digital RS485 interface supporting Modbus RTU or BACnet MS/TP protocols. Additionally, it offers dewpoint temperature (Td) data through Modbus RTU and BACnet MS/TP.
Featuring a functional design, the elegant enclosure adheres to regional standards and offers an optional display. Its construction simplifies installation, with a back cover housing push-in spring terminals separately from the electronics in the front cover. This allows easy commissioning by attaching the active part just before use and facilitates swift, tool-free replacement of the active component.
Configuration is streamlined for the digital version via PC, using the free PCS10 Product Configuration Software and an optional configuration adapter.
HTS201 is available in both US and EU formats, with or without a display, catering to different preferences and requirements.
