Frequently Asked Questions

What is Intrinsic Safety (IS)?

IS is a protection technique that ensures the electrical energy in the field circuit is too low to cause a spark or heat that could ignite a specific hazardous atmosphere.

Can I connect devices directly in the hazardous area to this module?

No. The 140DIO33000C is an IS module, but it must be used in conjunction with approved IS barriers or isolators located in the safe area. The barriers provide the final energy limitation.

What does "open collector" output mean?

It is a switching output that sinks current. When active, it connects the load to ground (0V). The field device must be supplied with 24V DC from an IS-approved power source.

Is hot swapping allowed for this module?

No. Hot swapping (removing/inserting while powered) is not permitted for intrinsically safe modules per safety standards. The system must be powered down.

What software configures this module?

It is configured within the PLC hardware configuration using Unity Pro, Concept, or ProWORX software. The software recognizes it as an 8-point IS output module.
