The new AMRIO series of programmable I/O modules is a full-featured replacement of the DMM-xx series. Only the DMM-DO18 has been replaced by AMRIO-DO21 with three additional digital outputs. The DMM-PDO6NI6 and DMM-AO8U do not have a direct replacement and are replaced with the AI8DO8, AI8RDO8 and AI8AO8U combined models.

AMRIO modules have an extended operating temperature range of –20 to 70 °C as standard. The modules are designed for mounting on a 35 mm DIN rail and for power supply of 24 V DC.

A qualitative functional change of AMRIO modules, as compared to DMM, is the upcoming possibility of programming a user application in the DetStudio development environment – this effectively means that AMRIO modules can become a small control system, easily and cost-effectively.

This week, we´ve started with the distribution of AMRIO modules that will gradually replace the discontinued DMM-xx modules that are still in stock. Thanks to the compatibility of both module series, this change should not have any significant impact on projects in progress or already implemented applications. If you have any questions, please contact our technical support or your AMiT sales representative.
