.. _OI-AnalogLS: OI-AnalogLS =========== Description ----------- The OI-AnalogLS module is analog input module designed to interface discrete sensors such as PT100, PT100, thermocouples, Wheatstone bridge, strain gauge, ... **Key Features:** * Analog inputs: There are 5 differential inputs available for reading low-voltage signals. * Multiple configurations: Excitation in voltage or current, as well as biasing voltage, are available, providing the possibility to connect various sensors to OI-AnalogLS. * Precision: With its 16-bit ADC, all inputs offer great precision, allowing the OI-AnalogLS to be used in demanding situations. Furthermore, all inputs are filtered to reject common-mode noise as well as differential-mode noise. **Compact Design:** The module comes in a compact BOI12 package, saving space in control cabinets. It's easy to install, with up to four modules fitting on a single rail. This scalability makes it simple to expand the system based on specific needs. .. note:: The OI-AnalogLS module functions either as a standalone unit (with user code injected directly) or as a slave unit (with user code executed on a Master module, receiving commands via the communication bus).
