The digital output I/O-Module MU110-24.8D.4R has 8 digital inputs which are implemented as switch contacts and NPN. In addition, there are also 4 digital outputs (relay) available. The module requires 24 V DC power supply and supports Modbus RTU/ASCII communication via a serial RS485 interface. The enclosure provides IP20 rating and can be operated in the temperature range between -20 and +55 °C.

The I/O Modules of MX110 series offer a cost-effective and flexible solution in distributed automation systems. The robust modules carry out on-site measured value acquisition and process control and are very suitable for extension of existing systems as well as for creating of new high-performance systems. Due to the proven RS485 bus technology and intelligent functions, such as pulse counter or sensor state diagnosis, the MX110 modules can be used in different fields, such as building technology, process industry, etc.
