Frequently Asked Questions

Q: Can the module output both current and voltage simultaneously?
A: Output type selection is configured per channel according to system design; each channel operates in either current or voltage mode as configured.

Q: Is the module suitable for safety-critical applications?
A: While highly reliable, the ASI533-S00/SS3S0 is intended for standard process control. Safety Instrumented Systems should use dedicated safety-rated modules.

Q: Does this module require external signal isolation?
A: No additional isolation is typically required, as the module is designed to meet Yokogawa’s internal isolation and noise immunity standards.
