The IN-HWD (rev 2) has the usual two RTD Pt100 inputs for the wet and dry bulb, two 4~20mA outputs for RH and dry bulb temperature, with no software required. The units come factory calibrated and no initial calibration is required when installed as per the Installation Guide.

Options are available for adding relay alarm outputs and/or serial port with Modbus RTU.

The alarm setup and the calibration (if required), is now done from the front key pad, not the RS485 like the old 2100-A4-HWD. The optional RS485 is not used for configuration.

Optional: The IN-HWD will connect to our MicroScan SCADA software for logging of the humidity and temperature via the optional RS485 Modbus RTU comms (requires the PLC Modbus driver for direct connection to MicroScan); alternatively connect via a Intech Micro I/O Remote Station using the two 4~20mA outputs (does not require the IN-HWD comms option).

Connection Example:

TYPE IN-HWD
Input1 x wet bulb, 1 x dry bulb.
Dual 3-wire RTD Pt100 DIN (JIS option).
Power supplyHV: 85~265Vac / 95~370Vdc.
