Amperite 50C30 Tube Thermostatic Delay Relay The Amperite 50C30 is a thermostatic delay relay designed to provide a fixed time delay of 30 seconds. Utilizing a heater-actuated mechanism, this relay operates effectively on both AC and DC currents, making it versatile for various applications. Key Features Time Delay: Fixed at 30 seconds. Heater Voltage: 50V AC/DC. Contact Configuration: Single Pole Single Throw (SPST) Normally Closed (NC). Contact Rating: 3A at 125V AC. Construction: Hermetically sealed glass envelope, ensuring durability and resistance to environmental factors. Mounting: 9-pin miniature base for easy integration into existing systems. Operational Overview Upon application of the specified heater voltage, the internal heater warms a bimetallic strip, causing it to bend and open the normally closed contacts after the predetermined delay of 30 seconds. This design ensures consistent and reliable timing performance. Applications The Amperite 50C30 is suitable for applications requiring precise time delays, such as: Sequential circuit operations. Motor control systems. Industrial automation processes. Protective circuits to prevent inrush currents. Environmental Considerations Designed to operate within a temperature range of -55°C to +80°C, the 50C30 relay maintains performance across various environmental conditions. Its hermetically sealed construction protects against moisture, dust, and other contaminants.
