The SEM1633 provides an accurate alarm / switching function when used with RTD or Slidewire sensors. 

The flexible design allows for the use of any resistive sensor within the range of (10 to 10,500) Ohms. 

This means that in the standard product Pt100, 500, 1000, Ni or Cu sensors as well as slide wire sensors up to 100 K, can be accommodated. 

Other sensor characteristics or your own 22 point linearisation characteristic (for slidewire or linear resistance) can be downloaded into the product enabling you to adapt it exactly to your application. 

Relay outputs are independently configured for action, set point and dead band. Six actions are provided, normal High/Low/Deviation and inverted High/Low/Deviation. 

For ease of use, a high efficiency switch mode power supply is fitted as standard and does not require any adjustment between ac or dc applications. Operating voltages are (10 to 48) Vdc and (10 to 32) Vac. 

Our USB interface is fitted for quick and easy configuration. Just connect a standard USB cable between the SEM1633 and your PC. 

Using our free configuration software, your PC will automatically upload the existing configuration data and guide you through any changes you wish to make. 

To further help save time, the SEM1633 does not need to be wired to a power supply during the configuration process, it is powered via the USB interface from your PC.
