Typical Application Scenarios

Power Generation & Utilities: Grid operators and power plant engineers depend on sub-millisecond timestamp accuracy for sequence-of-events (SOE) recorders. The 2XV9450-1AR22 serves as the GPS master clock feeding protection relays, fault recorders, and energy management systems — enabling precise post-disturbance analysis and NERC CIP compliance.

✅ Oil & Gas Processing: Offshore platforms and onshore refineries operate complex DCS and SIS networks where time skew between nodes can compromise safety interlock logic. This SICLOCK TM unit synchronizes all control nodes to a single authoritative source, eliminating race conditions in safety-critical sequences.

✅ Discrete & Process Manufacturing: High-speed production lines require coordinated timing across PLCs, robots, and quality inspection systems. The 2XV9450-1AR22 provides the time backbone that keeps batch records, OEE calculations, and MES data aligned to a common clock — essential for ISO 9001 audit trails.

✅ Rail & Transportation Infrastructure: Signaling systems and train control networks mandate precise time synchronization for safe operations. This unit’s IRIG-B and NTP dual-output capability makes it compatible with both legacy serial-based signaling equipment and modern IP-based control architectures.

✅ Pharmaceutical & Life Sciences: FDA 21 CFR Part 11 and GMP regulations require tamper-evident, accurately timestamped electronic records. The SICLOCK TM’s GPS-traceable time source provides the audit-ready timestamp infrastructure demanded by regulatory inspectors.

Technical Specifications & Selection Guide

Selection Tip: If your facility requires simultaneous NTP server functionality for IT networks alongside IRIG-B output for legacy protection relays, the 2XV9450-1AR22 is the single-unit solution that eliminates the need for separate time distribution hardware.
