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. FEATURES 8 analog inputs individually configurable Signal conversion from analog to SDI-12, RS485 and Modbus RTU Signal conversion from SDI-12 to RS485 and Modbus RTU Parallel SDI-12, Modbus RTU and analog output Acquisition of up to 99 variables Multiple sensor voltage supplies Additionally with MRL-IEa Signal conversion from SDI-12 and RS485 to analog Impuls output of acquired quantities, e.g. for flowmeters Parallel SDI-12, Modbus RTU, analog and impuls output SPECIFICATIONS Power supply 9…28 VDC, Overvoltage and reverse voltage protection, deep-discharge protected if used with optional battery Power consumption min. 0.65 mA @ 12V Sensor supply 500 mA @ 5 V 500 mA @ 12/14 V 500 mA @ switched supply voltage Referenced sensor supply 200 mA @ 2.5 V 100 mA @ 2.5 V (wind vane reference)
