Description Product Overview The Emerson SE3008 DeltaV™ SQ Controller is a compact and scalable controller. It delivers fast communication and precise control for small to moderate processes. This controller supports Electronic Marshalling with CHARMs based I/O. You can mount I/O anywhere to reduce cabinet space. The design removes mounting screws for quick assembly. Simply plug the unit in – it auto-addresses and auto-detects I/O. Upgrade from SQ to SX easily without changing existing configuration. Field proven processor and OS ensure reliable operation. Key Benefits at a Glance Scalable & Forgiving – Start with SQ, upgrade to SX late in projects. No hardware redesign needed. Fast Project Execution – Snap-on carriers, no dip switches, automatic I/O detection. Redundant Architecture – 1:1 redundancy for high availability. Online upgrade to SX. Advanced Controls – Supports Batch, Model Predictive Control, and Neural Networks. Rugged & Certified – Operates from -40°C to 70°C. Class I Division 2 and ATEX Zone 2.

Simply replace the SQ with an SX controller. All wiring, configuration, and I/O remain the same. Does the SE3008 support redundant power? The controller itself supports 1:1 redundancy. Use redundant power supplies for full system redundancy. How do I connect this to an existing DeltaV network? Plug the RJ-45 cables into Primary and Secondary control network ports. Open DeltaV Explorer and use Auto-Sense. What is the real-world maximum I/O count for this model? Around 750 DST points. For heavy advanced control, keep execution rates at 500ms or slower. Can I use this with 3300 XL 11 mm Proximity Probes? Yes. Connect through compatible DeltaV S-series I/O cards. View 3300 XL 11 mm Proximity Probes here. Do I need configuration software? Yes. Use DeltaV Control Studio (IEC 61131) to create control strategies. Selection Guide (How to Choose) Choose SQ Controller (SE3008) if: Your DST count is under 750. You need Electronic Marshalling. Budget is a priority. Space is limited. Choose SX Controller instead if: You need larger user memory. Your process has more than 1000 DST points. You require faster execution below 100ms. Redundancy? Order two SQ controllers. The system detects them automatically. Need marine approval? SQ includes IACS E10. No extra option needed. Diagnostic Capabilities Automatic I/O detection and self-addressing Time-stamped event and alarm reporting Redundancy status monitoring (Active/Standby LEDs) Control network health check via Pri.
