The MRL-IE is a compact data acquisition module designed to acquire, process and transmit all sorts of environmental data.It is compatible with all sensors offered by SOMMER Messtechnik and numerous third-party devices equipped with analogor SDI-12 interfaces. The MRL-IE extends the input ports of MRL data loggers and offers conversion between RS-485 and SDI-12 signals.

The MRL- IE a is equipped with an additional analog output board that adds multiple analog, pulse and digital switch outputs.
