MultiTek DC Current or Voltage 1 Input 3 Outputs Transducer
| SELECTION GUIDE M100-DM3 One input three outputs TYPICAL APPLICATIONS The M100-DM3 takes 1 DC Input and provides 3 isolated outputs all directly proportional to the input. The outputs can all be of the same D.C. Value or can be different. Typically this product is used to prevent earth loops between measuring devices. For example the M100-DM3 could have its input signal provided by a M100-WA4 watt transducer with 4-20mA output. The 3 outputs from the M100-DM3 could be as follows. Output A = 4-20mA fed to a PLC. Output B = 0-20mA fed to a analogue meter scaled in kW. Output C = 1-5 volt fed to a chart recorder. The isolation between the Input / Output / Case is 1.5kV and the isolation between each output is 500 volts. ORDERING INFORMATION Product Code Input In Output Aux. Freq.
