The OMX 312UNI type is a galvanic isolated single-channel universal signal converter / splitter. It can be configured for 10 different input variants. Setting of both the input and output ranges can be done conveniently by a DIP switch located on the side of the housing or from a PC via the OM Link SW.”You can also use this converter as a splitter into 2 analogue outputs.
This device is based on a microprocessor with a 24-bit ∆∑ A/D converter, which guarantees high accuracy and excellent stability.
