General Questions

What does IP67 mean?
IP67 indicates the level of protection the module offers against dust and water. The “6” signifies complete protection against dust ingress, while the “7” means the module can withstand immersion in water up to 1.0m deep for 30 minutes.

What are I/O modules used for?
I/O modules are used to interface sensors, actuators and other field devices with a control system. They facilitate the input and output of signals in automation systems.

Technical Specifications

What voltages do Industrial I/O Modules typically support?
Molex Industrial I/O Modules typically support a voltage range of approximately 19V to 28V DC. It is important to check the specific product datasheet for exact voltage specifications.

What types of signals can these modules handle?
Molex Industrial I/O Modules can handle digital (both input and output) signals.

Installation and Maintenance

How do I install an I/O module?
Installation involves mounting the module in a suitable location, connecting the field devices to the module, and ensuring proper power and network connections. Always refer to the user manual for specific instructions.

What kinds of connectors are used for these modules?
Molex Industrial I/O Modules use M8 or M12 connectors for field device connections due to their robust design and ease of use. Fast and secure Ultra-Lock connectors accelerate changeover operations, while threaded Mini-Change connectors are also available for greater flexibility.​

Environmental Considerations

Can these modules be used in extreme temperatures?
Yes, Industrial I/O Modules are designed to operate at 100% capability in a wide range of temperatures ranging from -20 to +70°C.

Are I/O modules resistant to chemicals?
IP67 modules generally have some degree of chemical resistance, but this can vary. It’s important to verify the module material’s compatibility with the specific chemicals it will be exposed to.

Safety and Troubleshooting

Are Industrial I/O Modules compliant with industry standards?
Yes, they are designed to comply with relevant industry standards for safety, electromagnetic compatibility (EMC) and environmental protection. Check the product documentation for specific certifications.

Can I perform a firmware update on the module?
Firmware updates typically involve connecting the module to a computer via its communication interface and using the manufacturer’s software tool to upload the new firmware. Molex I/O Ethernet modules support firmware updates.
