The SCM9B-1000/2000 Sensor-to-Computer Modules are a family of complete solutions designed for data acquisition systems based on personal computers and other processor-based equipment with standard serial I/O ports. The modules convert analog input signals to engineering units and transmit in ASCII format to any host with standard RS-485 or RS-232C ports. These modules can measure temperature, pressure, voltage, current and various types of digital signals. The modules provide direct connection to a wide variety of sensors and perform all signal conditioning, scaling, linearization and conversion to engineering units. Each module also provides digital I/O lines for controlling devices through solid state relays or TTL signals. These digital I/O lines along with built-in limit setting capability provide alarm and control outputs.

The 2000 series is an enhanced version of the 1000 series of sensor interfaces. The 2000 series allows the user to scale the output data in any desired engineering units. The 2000 also provides the ability to program nonlinear transfer functions. This feature may be used to linearize non-standard sensors or to provide outputs in engineering units which are nonlinear functions of the input.
OPC-UA is supported by many of our communication and I/O products. If you are interested but not quite sure how to implement OPC-UA into your factory then get in touch.
