Honeywell FC-SAO-0220M Safe Analog Output Module

Frequently Asked Questions (FAQs)

Q1: How many output channels does the FC-SAO-0220M module provide?
A1: The module provides two galvanically isolated analog output channels, each capable of 0–20 mA or 4–20 mA operation.

Q2: Can the module be used with inductive loads?
A2: No. Only resistive or capacitive loads are allowed. Inductive loads can result in fault detection.

Q3: What is the resolution of the D/A converter used in each channel?
A3: Each analog output channel uses a 12-bit digital-to-analog converter.

Q4: How does the module ensure safety in case of signal faults?
A4: The module includes diagnostic tests and a secondary means of de-energizing (SMOD) per channel, allowing outputs to be forced off by the processor or watchdog.

Q5: What is the maximum loop resistance allowed for active output configuration?
A5: The maximum allowable loop resistance in active mode is 600 ohms.

Q6: What certifications does the FC-SAO-0220M module comply with?
A6: It complies with CE, TÜV, UL, CSA, and FM standards.

Q7: Is it possible to configure redundant analog outputs using this module?
A7: Yes, starting from Safety Builder release 120, the module supports redundant analog output configurations.

Q8: What should be done with unused outputs to avoid fault detection during self-test?
A8: Unused outputs must be shorted during self-tests to prevent false fault detection.
