Description
Product Introduction
Let’s be honest: finding a spare METSO A413792 when a critical Neles valve goes offline is a panic moment. This module isn’t the star of the show, but it’s the translator between your DCS and the final control element.
The METSO A413792 handles the analog grunt work—feeding position commands to the actuator and reading back the actual stem position. It supports HART, which means you can troubleshoot valve health without suiting up for the field. For the maintenance team, this is the difference between a quick fix and a full system drain.

Common Replacement Pitfalls
Replacing a in a live plant is a high-wire act. Get these wrong and you’ll be explaining the downtime to the plant manager.
Firmware Revision Mismatch
The new module might have a newer firmware version that the old ND9000 rack doesn’t recognize. Always check the rack firmware before ordering. If the rack is on v2.1, don’t send a module on v3.5 — it will sit there blinking red.
DIP Switch / Jumper Misconfiguration
This module has address switches. The factory default is usually 0. Your rack slot might need 3. Take a photo of the old module before you pull it. Seriously. It saves the headache of digging through the config software later.
Connector / Terminal Incompatibility
The uses a removable terminal block. The pinout is standard, but if you’re reusing old field wiring, double-check that the +24 V and 0 V aren’t swapped. It happens more than you’d think.
Power Budget Shortfall
One draws about 1.5 W. Add 10 of them, plus the CPU and comms cards, and you’re near 50 W. Make sure your chassis power supply has headroom. A dying PSU will crash the whole rack when you add a new load.
ESD Damage
Don’t touch the backplane fingers with bare hands. Use a wrist strap. I’ve seen a tech kill a $1,200 module by setting it on a nylon carpet and sliding it into the rack. The spark was small, but the charge fried the input buffer.

FAQ
Q: Can I just swap this in directly?
A: Yes, but only if the firmware matches. If your controller is older than 2010, contact us to verify the firmware version on the module.
Q: Is this module compatible with the Neles ND9000?
A: Directly compatible. It fits the ND9000 fieldbus rack.
Q: My system runs Valmet DNA — will this work?
A: Yes. The is backward compatible with Valmet DNA systems.
A: The is the standard 4-20 mA I/O. The A413790 is a specialty module with different signal types — don’t mix them unless the config software says it’s okay.
Q: Do you offer a warranty?
A: 12 months. If it fails under normal operation, we replace it — no questions asked.
Q: Is this new or refurbished?
A: New Original (New Surplus). It has never been installed, but it might not be in the original retail box.
Q: How do I know if the firmware is correct?
A: We can test it against your specific controller version if you provide the firmware number. Just ask.
