- OEM Signal Integrity – Maintains certified accuracy and diagnostic reporting within the Metso platform.
- Reduced Commissioning Risk – Eliminates compatibility unknowns associated with third-party substitutes.
- Full Diagnostic Support – Supports Metso DNA system-level fault diagnostics and health monitoring.
Typical Applications
- Pulp & paper mill process control (e.g., digester, bleaching, recovery boiler)
- Power plant auxiliary systems and boiler control
- Oil & gas upstream/downstream discrete signal monitoring
- Chemical plant safety interlock and ESD systems
- Water treatment plant pump and valve status monitoring
- General industrial DCS-based discrete I/O acquisition
System Compatibility
- Metso DNA – Full native compatibility (primary platform)
- Metso Automation / Neles Controls legacy systems – Compatible with appropriate backplane revision
- Third-party DCS platforms – Not directly compatible; requires gateway or I/O conversion hardware
Always confirm the system firmware version and I/O bus specification with your DCS engineer before ordering a replacement module.
Selection Guide
Use the following criteria to select the correct digital input module for your application:
- Channel Count – Verify the number of DI channels required (8, 16, or 32 ch variants may exist).
- Input Voltage Range – Confirm field device signal voltage (24VDC, 48VDC, 120VAC, etc.).
- Isolation Type – Optically isolated inputs preferred for noise-sensitive environments.
- Backplane Slot Type – Match the physical connector and bus protocol to your existing I/O rack.
- Firmware Revision – Ensure module firmware is compatible with your DCS controller version.
- Hazardous Area Rating – If installed in Zone 1/2 or Div 1/2, confirm ATEX/IECEx certification.

Replacement & Compatibility FAQ
Q: Can I replace IOP345 091124 with a different Metso DI module?
A: Possibly, if the channel count, voltage range, and backplane connector match. Contact us with your system details for a verified recommendation.
Q: Is a refurbished IOP345 091124 reliable for critical process control?
A: Yes, when properly tested and certified. Our refurbished units pass full functional testing and include a 12-month warranty.
Q: Can this module be used in a non-Metso DCS system?
A: Not directly. It is designed for the Metso DNA platform. Cross-platform use requires engineering evaluation and potentially a protocol gateway.
Q: What is the lead time for a new IOP345 091124?
A: Typically 3–10 business days for stock items. Contact us for current availability.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Request documentation via support@konmask.com after placing your inquiry.
