Honeywell FC-SAO-0220M Safe Analog Output Module Original

Frequently Asked Questions (FAQs)

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

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

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

How does the module ensure safety in case of signal faults?
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.

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

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

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

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