AD-MM 400 FE


The Monitor module AD-MM 400 FE is a display and control unit for front panel mounting. The device can be used as master or slave. As a master, the device reads the displayed values of devices that are connected via the RS485 interface with the AD-MM 400 FE. The display values are polled at a certain time frame. The display values can be any data such as measured values, output values, digital inputs or outputs or various counters for energy or amounts. In addition to the display function, the AD-MM 400 FE can configure the connected devices via the menu. As a slave, the device can also be used as pure display device, where the display values are then sent from a master to the AD-MM 400.
