Frequently Asked Questions (FAQ)

• What safety level does the X-AO 16 01 support? It meets SIL 3 requirements for safety systems.
• Can I use HART communication with this module? Yes, but accuracy reduces to ≤ ±2% of final value.
• Are the outputs isolated from each other? Yes, pairwise galvanic isolation applies.
• What happens during a fault condition? The module shuts down outputs within 16 ms to a safe state.
• Do I need the X-CA 011 cable? Only if you use the X-CB 014 53 connector board.
• What is the LSB value? The least significant bit equals ≤ 2 µA.
