Key Points
- 10A resistive rating
- Hand Off Auto option with tamper resistant cover
- Current run-status confirmation option
- UL/ULC, CE listed
- RoHOS compliant
Applications
- Command contactors
- Control motors
- Isolation
- Device interlocking
- Relay logic
- Lighting load levels
The PR Series pilot relays are ideal multi-voltage input pilot duty relays that mount to existing panels to control loads. External enclosures are not required making them ideal for interfacing loads with building automation control systems. Featuring the highest output in the smallest package, integrated current sensing, and a secure tamper resistant HOA.
Convenient and cost-effective control
- Current sensor run status option
- LED indicator
- Multi-voltage coil input
- Hand-Off-Auto switch option
Compact enclosure mounts externally for easy installation
- Nipple mount to any electrical enclosure
- Flexible tinned stranded wire… fits easily in tight spaces and provides secure connections to wire nuts
Concealed HOA switch with screw secured cover prevents tampering
- Versions with Hand Off Auto (HOA) switch feature with secure screw cover door to prevent tampering
- Eliminates costly system override related service calls
Current sensing run status confirmation
- Provides feedback that pilot device relay coil is powered
