Field Device Compatibility

The types of field devices that can be connected to the channels of the 10106/2/1 module depend on the signal converter used:

Notes:

1. Using dry contacts with line-monitoring function requires a line terminator with a 10 kOhm resistor and a 1 kOhm resistor ±10%, 0.25 W.
2. The combination of fail-safe sensors with the fail-safe input module 10106/2/1 meets the safety integrity requirements as laid down in IEC 61508.
3. A maximum of 8 channels per 10106/A/2 converter may be used for dry contacts without a line-monitoring function.

Self-test Features

The self-test, controlled by the FSC system's central processor unit (CPU), includes:

• Functional tests of various trip levels applied
• Channel independence verification
• Monitoring of supply voltage to input devices
• Earth connection correctness verification
• Correctness of supply voltages utilized
