Global PLC Spare HUB Review

The IC694MDL940 is a reliable workhorse for mixed-voltage environments. Its single-slot design saves valuable rack space. Note that because it lacks internal fuses, we strongly recommend external protection to prevent damage during field shorts. Its mechanical relay life of up to 1 million operations makes it a long-term staple for industrial automation infrastructure.

• Warranty: 12-Month Quality Assurance.
• Shipping: Worldwide express delivery via FedEx, UPS, or DHL.
• Handling Time: Standard dispatch within 24-48 hours.

FAQ & Professional Guidance

What is the contact form of the IC694MDL940?

It uses Form A contacts, which are Normally Open (N.O.). The circuit is only closed when the PLC logic sends an "On" signal to the channel.

Can I use this module to switch very small signals?

The IC694MDL940 has a minimum load requirement of 10 mA. If your signal is lower than this, the relay contacts may not perform reliably over time.

Are the groups isolated from each other?

The outputs within a group share a common, but the four groups are isolated from each other, allowing for different voltage sources (e.g., AC and DC) on the same module.

Does the IC694MDL940 support hot-swapping?

While the RX3i backplane supports hot-swapping, it is always recommended to remove field power from the relay commons before extracting the module to prevent arcing.

How do I protect the internal relays from inductive kickback?

For DC loads, use a diode across the load. For AC loads, an RC snubber circuit is the best practice to extend the life of your IC694MDL940 contacts.
