11-pole configuration enables complex sequencing within a single device, reducing panel wiring and potential misconnections; this translates to fewer field faults and faster commissioning in hazardous-area panels. The 12-hour timing capability delivers consistent process intervals, cutting manual intervention and improving batch repeatability in chemical processing or water treatment applications. Aluminum enclosure provides robust corrosion resistance and lighter weight, lowering maintenance costs and enabling easier installation in coastal or offshore environments. NEC/CEC compliance and Hazardous/Classified Locations ratings across Class I, II, and III divisions simplify regulatory approvals and contractor qualification, accelerating project timelines and improving audit readiness. The compact 3.5 inch depth and overall footprint fit standard DSD-TS timer bases, streamlining retrofits and reducing enclosure remodeling. Compatibility with Eaton Crouse-Hinds explosionproof timers enables scalable control architectures and reliable long-term operation in harsh conditions. Industry insights show that using a purpose-built hazardous-area timer reduces unplanned downtime and extends the service life of critical automation loops.

FAQs
Install the DSDTS11H12SA within an explosion-proof enclosure appropriate for the location’s Class I/II/III rating. Mount firmly to a compatible timer base, connect inputs and outputs across the 11 poles per Eaton’s wiring diagram, tighten terminal screws to the specified torque, and seal the enclosure to maintain the hazardous-area integrity. Refer to the Eaton installation sheet for sequence and interconnect details.
The timer carries NEC/CEC standards and Hazardous/Classified Locations ratings across Class I, II, and III divisions, including Class I, Division 1 and Division 2 as applicable. These certifications confirm the device is suitable for explosive atmospheres and can be safely used in petroleum, chemical, and similar environments, ensuring regulatory compliance and safer operation.
Yes. The DSDTS11H12SA is designed to integrate with standard DSD-TS explosionproof timer bases and common hazardous-area enclosures. Its 11-pole configuration and compact 3.5 inch depth support straightforward retrofits and scalable control architectures within existing Eaton Crouse-Hinds timer families.
Ideal for oil and gas process control, chemical processing interlocks, mining and mineral processing, and marine equipment control, the timer supports 12-hour sequencing, long-term reliability, and compliant operation in hazardous-classified locations, helping automate duty cycles and reduce operator intervention.
The aluminum construction and explosion-proof design minimize corrosion-related failures, lowering maintenance costs over the device life. Its 11-pole architecture reduces wiring complexity, accelerating commissioning and reducing field labor. In safety-critical processes, predictable timing and compliance also minimize downtime and compliance-related penalties, delivering a favorable return on investment over typical lifecycle periods.
