Product Details
This multifunctional isolation amplifier and line conditioner interfaces and/or converts an analog process signal for computers and industrial control equipment such as PLC´s, PC’s or any other control equipment. Isolating amplifiers are also used used to avoid interference signals caused by earth ground-loops. Also the unwanted connection between the PLC to protective earth is no longer a problem source. The M3042 has also the possibility to feed loop powered transmitters directly without the need of an external power supply. Most common is the conversion of any input signal to a standard output signal.
Example:
Convert and isolate a process signal of 25.5V to 78.2V non linear voltage signal to a linearized 4 … 20mA standard signal,which is connected to a measurement equipment. Of course there is no galvanic connection between the input /output / power supply.An additional application is to extract and isolate the measuring signal out of 2-wire transmitter’s power supply. Input, output and supply are isolated against each other.
Signal inputs: DC/AC voltage, DC/AC current, frequency and platinum /nickel sensors.
Signal outputs: DC Volt, DC current and RS485 Modbus RTU.The amplifier is field programmable by means of a USB data cable connected to a Laptop. The set-up software Mpro is free of charge and is distributed via MOSTEC AG. The range of the isolator can be ordered factory programmed, free of charge. In this case all the labels are printed with the programmed range by MOSTEC AG.
The power supply is galvanically isolated from input and output and the voltage range of the supply is from 20 to 253VAC/DC.

Load cell type M2428-14
Code: Product Details The M2428-14 is a low-cost load cell to measure weights or forces in the range of 25kg (~250N) to 30'000kg (~300'000N). The bending beam consists of a strain gage sensor with integrated electronics to convert the force or weight to a 4…20mA signal. There is no need to use external, sensitive strain gage amplifiers or signal conditioning devices. A cell connects directly to any 2-wire sensor input of process control computers or other control equipment and displays. The bending beam confirms the protected class IP67 an delivered with open cable ends. Any range within the measuring range can be programmed. E.g. 45kg to 420kg = 4 to 20mA within a calibrated range of 0 to 500kg.
