For M400 2-w, M400 FF and M400 PA, the optical
oxygen sensor needs to be powered separately with
an appropriate power supply.

4.2.3 Analog connection to transmitter or controller

The InPro 6860 i is equipped with two different inter-
faces:
1. Digital communication to the transmitter and any
Modbus system.
2. Analog output (nA or 4 – 20 mA) plus a simulated
NTC 22 kΩ temperature signal. The mA version
includes HART communication.
a
Attention: Never connect an InPro 6860 i with mA
output to a nA input. This could damage the electron-
ics of the sensor and/or the instrument the sensor is
connected to.
