1. General Precautions

The system must be used only in accordance with the required protection level.

The sensor must be protected against accidental knocks and used in accordance with the instrument’s ambient characteristics and per-

formance levels.

Sensors must be powered with non distributed networks.

For outdoor installations or with cables longer than 30 m*, proceed as indicated at paragraph 3.

(*) See further limitations for Safety applications at paragraph 5.

2. Transmitters with amplified analog output

Transducers: KH SIL2 series

Outputs: 0.5...10.5V; 0.5...5.5V; 0.1...10.1V; 0.1...10V; 1...5V; 1...6V; 1...10V; 0.2...10.2; 0.5 … 4.5V ratiometric; 4...20mA, etc...

Installation remarks

- The transducer must be grounded (normally through the machine body or equipment it is installed on).

- Use a shielded cable only. The cable shield must be grounded on PLC side and left floating on machine side (on KH version with M12

  electrical connector it’s possible to connect the shield on machine side by leaving floating the PLC side).

- To prevent interference, separate the power cables from the signal cables.
