Frequently Asked Questions
What does “intrinsically safe” mean for this module?
It means the module limits electrical energy. It cannot spark and ignite flammable gases or dust. This allows safe use in classified hazardous areas.
What type of devices can I control with it?
You can control IS-certified devices like valve positioners, I/P converters, and variable speed drives in hazardous zones.
What is a key wiring consideration?
You must use properly certified intrinsic safety barriers or isolators between this module and field devices. The module itself is not a barrier.
Can I replace the module while power is on (hot swap)?
No. Hot swapping is not allowed for intrinsically safe modules. You must power down the system to maintain safety certification.
How do I select the right analog output module?
Choose the 140AIO33000 if you need to send control signals (like 4-20mA) into a Class I, Division 1 hazardous area from a Quantum PLC.
