ME544 (Discontinued)
4-channel Power Supply for 2-wire Transmitters
ME544 has four galvanically isolated supply channels for 2-wire transmitters.
The output voltage for each channel is 25 VDC.
Each channel is short-circuit protected and has a current limitation to protect measurement circuits from damage caused by short circuits or other faults.
ME544 cuts the risk for measurement errors caused by earth potential differences with a number of 2-wire transmitters in the same measurement system.
- 4 galvanically isolated supply channels for 2-wire transmitters
- 25 V stabilized supply voltage
- Short-circuit safe
- Current limited to ~35 mA
- Available for AC or DC power supply
- Compact mounting on DIN rail
- Plug-in screw terminals
