Tyco Electronics ETR14D3E004 Time Delay Relay

The Tyco Electronics Agastat ETR14D3E004 Time Delay Relay is a nuclear-qualified, DC-coil timer with four Form C changeover contacts in a socket-mount package, designed for precise sequencing and interlock functions in demanding industrial and nuclear-grade control panels. The unit uses a 125 VDC coil, delivers an on-delay timing function in the 4 to 120 second range after coil energization, and offers four independent Form C contacts rated to 10 A, enabling multiple simultaneous switching paths in automation circuits. Its ambient operating temperature rating reaches up to 40°C (104°F), and its nuclear qualification ensures suitability for safety-critical and regulated environments where reliable timed control is essential. As part of the Agastat family, the ETR14D3E004 emphasizes plug-in convenience through its socket-mount design, supporting straightforward installation with compatible bases and sockets while delivering repeatable timing performance across applications such as equipment start-up sequencing and process interlocks.
