SR469-P5-H-A20-T
Product Name
Allen-Bradley (Rockwell Automation) ControlLogix Series Safety Relay Module with High-Current Outputs (Model: SR469-P5-H-A20-T)
(Model Naming Interpretation:
- SR469: Core product line prefix for Allen-Bradley’s ControlLogix “Safety Relay” modules, denoting compatibility with ControlLogix 5580/5570 PLCs and membership in the “SR460” family of high-integrity safety components.
- P5: Functional identifier for “Power & Configuration”; “P” specifies a pluggable terminal design (for easy wiring/maintenance), “5” indicates 5 safety-related output channels (optimized for multi-circuit safety control).
- H: Performance suffix for “High-Current”; confirms support for high-power output loads (up to 10 A per channel), enabling direct control of heavy-duty actuators (e.g., motor contactors, large solenoid valves) without external relays.
- A20: Application & Compliance code; “A” denotes compliance with global safety standards (IEC 61508 SIL 3, EN ISO 13849-1 PL e), “20” specifies firmware revision 2.0 (enhanced diagnostic logging and safety loop validation).
- T: Environmental suffix for “Temperature-Rated”; indicates extended operating temperature range (-40℃ to +70℃), suitable for harsh industrial environments (e.g., foundries, outdoor installations).
- Core Positioning: The “high-current safety relay hub for ControlLogix systems,” enabling direct control of heavy-duty safety actuators while maintaining SIL 3/PL e compliance—critical for high-risk applications like press machines, conveyors, and robotic workcells. )
2. Product Description
The SR469-P5-H-A20-T is a dedicated safety relay module developed by Allen-Bradley for the ControlLogix Distributed Control System, a flagship platform in industrial safety automation (automotive, aerospace, heavy manufacturing). It integrates 5-channel high-current safety outputs, SIL 3/PL e compliance, real-time fault diagnostics, and rugged environmental design to address three key challenges of high-power safety control:
- High-Current Safety Actuation: Delivers 10 A continuous current per output channel (20 A peak for 100 ms), enabling direct control of heavy-duty safety actuators—such as 480 V AC motor contactors (e.g., Allen-Bradley 3RT20) or large solenoid valve
