Product Introduction
The Metso A413746 (BOR86) is an 8-channel binary (discrete) digital output module used in Metso Cisel and Valmet automation systems. It switches 18–32 VDC field loads such as solenoid valves, indicator lamps, and small contactors, providing isolated digital outputs from the controller layer in power, petrochemical, and pulp & paper plants.
This module is chosen for its compact 8-point density, 500 mA per channel capacity, and proven reliability in legacy Metso/Valmet DCS installations where replacement availability is critical. The A413746 is cross-referenced as 09 26031500 and S436406, making it a direct replacement for older Valmet and Neles Automation output cards.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| All outputs stuck OFF | Module power supply or backplane communication fault | ❌ Low | Measure 24 V DC at module power terminals; check controller I/O status | Check PSU, fuses, and backplane communication before replacing module |
| Single output won’t turn ON | Field wiring open, blown fuse, or load failure | ❌ Low | Measure voltage at output terminal with load commanded ON; check fuse | Repair field wiring or replace load/fuse; module likely OK |
| Output turns ON but load doesn’t energize | Insufficient voltage or current capacity | ⚠️ Medium | Measure terminal voltage under load; compare to load nameplate current | Verify load current ≤ 500 mA/channel; reduce load or add parallel module if needed |
| Intermittent output dropouts | Loose terminal block or backplane contact | ⚠️ Medium | Reseat module and terminal block; inspect terminals for corrosion | Clean contacts, reseat firmly; replace only if problem persists after reseating |
| Output channel reads inverted logic | Sourcing vs. sinking wiring mismatch | ⚠️ Medium | Verify field wiring polarity and common voltage reference | Correct wiring to match module output type (sourcing/sinking) |
| Module fails after swap | Wrong voltage type (24 VDC vs. 120 VAC) or channel count mismatch | ✅ High | Compare old module label (A413746, BOR86, revision) before removal | Match exact part number and output type on replacement |
| ERR or COMMS LED flashing | Module not communicating with controller | ✅ High | Read I/O diagnostic buffer in Cisel/Valmet engineering tool | Usually requires module replacement or configuration check |
If you’re stuck, send photos of the module label, terminal block wiring, and any controller I/O diagnostic screens. We’ll review them before you commit to a swap.
Frequently Asked Questions (FAQ)
Q: What’s the difference between A413746 (BOR86) and A413140 (BIU-8)?
A: The A413746 (BOR86) is an 8-channel binary output module, while the A413140 (BIU-8) is an 8-channel binary input module. Both are part of the Metso/Valmet Cisel I/O family and use similar 24 VDC architecture, but they serve opposite functions. They are not interchangeable.
Q: Is this module hot-swappable?
A: No. Metso Cisel/Valmet I/O modules are not designed for hot-swap. Pulling or inserting them under power can damage the backplane or adjacent modules. Follow your plant’s approved procedure—usually this means taking the I/O rack or controller offline before swapping.
Q: Can I use this module in non-Metso/Valmet PLC systems?
A: No. The is built for Metso Cisel and Valmet automation backplanes and communication architecture. It won’t work in Allen-Bradley, Siemens, or other vendor racks without significant reconfiguration and custom interfacing.
Q: Will my I/O mapping and logic survive a module swap?
A: Yes. The I/O addresses and logic live in the controller memory, not on the output module itself. As long as you replace it with the same type and keep wiring identical, the I/O map remains valid. Always back up your controller database before hardware changes.
Q: Why is this cheaper than buying direct from Metso?
A: This is new surplus or inspected stock from decommissioned systems and authorized distributors. It’s genuine Metso/Valmet hardware, function-tested, but sold as surplus rather than factory-direct new. That’s why the price is lower while still carrying a 1-year replacement warranty.
Q: What condition is the unit in—new, used, or refurbished?
A: We list each unit explicitly: “New Original / New Surplus” means factory-sealed or unused surplus with original packaging; “Refurbished (tested)” means cleaned, electrically tested, and verified functional on a Metso Cisel/Valmet I/O test rig. The product page or quote will state which applies.
Q: Do you provide test reports or power-up videos?
A: Yes. For refurbished units, we can supply a basic functional test report (power-on self-test, communication handshake, sample output channel verification with 24 VDC loads) and short power-up video on request. Just ask before purchase.
