Overview
The Nolatron 3371D-5 is a proven anti-tiedown time delay relay for industrial machine control applications. Rated 115VAC, this relay enforces synchronized dual-switch operation to meet OSHA safety requirements. Anti-tiedown controls are used with two start switches to protect machinery operators and comply with OSHA regulations requiring operators to keep both hands on the start switches during machine cycles. The 3371D-5 delivers reliable timing and output control for press machines, automated assembly lines, and other hazardous equipment requiring operator protection.
Key Features
- Anti-Tiedown Protection: Prevents single-switch lock-down by requiring both switches to activate within a fixed time interval
- 115VAC Operation: Standard industrial control voltage for factory and plant environments
- 11-Pin Socket Configuration: Plug-in design for easy installation and replacement
- OSHA Compliance: Helps comply with OSHA regulations and minimizes the possibility of operators starting machines with a hand in the work area
- Time-Delay Output: Adjustable timing for synchronized control sequences
- Industrial-Grade Reliability: Built for harsh manufacturing environments with proven performance across decades of use
