- Output 4…20mA, 2-wire-technics
- 24VDC power supply, galvanically isolated
Product Details
The very small measuring pH amplifier type M2920-1-W converts the digital electrode signal from Mettler Toledo ISM pH sensors InPro directly to a 4…20mA 2-wire signal.
The M2920 works with a resolution of 12 bit, is pre-calibrated and connected between the electrode and signal acquisition instrument (e.g. PLC).
Programmable logic controllers (PLC) or other controllers can be connected directly.
The Input is galvanically isolated from the output and power supply.
The robust housing confirms the protected class IP67 and allows application in rough environments.
