Analog inputs 2 x 4…20 mA / 0…10 V

HC-003-41 is an all-round analog input module for use in the MULTICAL® 603 and MULTICAL® 803 energy meters. The analog signals can come from sensors, which are often used in industry, or from sensors that are used in building automation, e.g. temperature, pressure, air velocity, air energy content and air humidity sensors. Typically, sensors emit 4...20 mA or 0...10 V signals. The module writes the values of the analog signals to the P1 and P2 registers of the meter. The analog signals can be read from the meter display, and at the same time, they are logged in the memory of the meter. The analog signals can also be remotely read via the many various communication modules that are available for MULTICAL® 603 and MULTICAL® 803. In addition to the scaling of the min. value, max value and decimal position of the signal inputs, various measuring units can also be allocated, e.g. bar, m/s, %RH, etc. The reading speed of the analog inputs can be selected between a number of intervals ranging from 1 second to 1 hour. A quick reading enables the analog signals to be used for control and regulation purposes. The analog inputs are galvanically separated from the meter. The module supplies the connected sensors via an isolated power supply, which also supplies the module itself.
