700-PH100A1 ALLEN-BRADLEY Pneumatic Delay Relay

Review ALLEN-BRADLEY New Ser Pneumatic Time Delay Relay/700-pkt

The Allen-Bradley 700-PH100A1 Pneumatic Delay Relay, also known as the 700-PKT, is a versatile and reliable pneumatic control component designed to provide precise timing and sequencing functions in industrial automation applications. This delay relay is an essential addition to any control system that requires the ability to delay or time the operation of pneumatic actuators.

The 700-PH100A1 is a single-pole, double-throw (SPDT) relay, meaning it can switch one pneumatic signal to another after a predetermined delay. The delay time is adjustable from 25 to 399 milliseconds, making it suitable for a wide range of applications. The relay features a built-in adjustment knob, which allows for easy and accurate adjustment of the delay time without the need for additional tools.

The relay body is constructed of brass, ensuring durability and resistance to harsh environments. It operates on a standard pneumatic supply pressure of 3 to 15 psi (0.2 to 1.0 bar), and the coil consumes approximately 0.25 kW-hr per thousand operations. The contact rating is 10 amps at 277 volts AC and 125 volts DC, and it is suitable for use in applications with a maximum ambient temperature of 104 F (40 C).

The Allen-Bradley 700-PH100A1 Pneumatic Delay Relay has a compact size of 1.6 x 2.6 x 1.2 inches (4.1 x 6.6 x 3.0 cm), making it easy to install and integrate into any control system. It is compatible with a wide range of Allen-Bradley and Rockwell Automation control systems, including the ControlLogix, CompactLogix, and MicroLogix families.

The 700-PKT also features a rugged design, with a sealed contact chamber that protects against debris and moisture, ensuring long-lasting performance even in the most demanding industrial environments. It is also suitable for use in hazardous locations, with approvals for Class I, Division 2, Groups E, F, and G; Class II, Division 1, Groups E, F, and G; and Class III, Division 1, Groups E, F, and G.

In summary, the Allen-Bradley 700-PH100A1 Pneumatic Delay Relay is a versatile and reliable pneumatic control component designed to provide precise timing and sequencing functions in industrial automation applications. Its adjustable delay time, rugged design, compact size, and compatibility with a wide range of control systems make it an essential addition to any control system where the ability to delay or time the operation of pneumatic actuators is required.

The Allen-Bradley 700-PH100A1 Pneumatic Delay Relay/700-PKT is a pneumatic relay designed to provide a programmable delay function in pneumatic control systems. This device is often used in process control applications where precise timing is required. Here are some pros and cons of buying this particular model:

1. Programmable delay function: The Allen-Bradley 700-PH100A1 allows users to set the desired delay time, providing flexibility and precision in control applications.

2. Pneumatic operation: This relay operates using compressed air, making it suitable for use in harsh environments where electrical components may not be practical.

3. Robust design: The relay is designed to withstand the rigors of industrial environments, including vibration, shock, and temperature extremes.

4. Easy installation: The relay is designed to be easily integrated into pneumatic control systems, with simple wiring requirements.

1. Limited delay times: The maximum delay time for this relay is 25 seconds, which may not be sufficient for some applications.

2. Requires compressed air: The use of compressed air as a power source may require additional infrastructure and costs for compressor installation and maintenance.

3. Limited configurability: While the delay function is programmable, other features of the relay may be less configurable than their electronic counterparts.

In conclusion, the Allen-Bradley 700-PH100A1 Pneumatic Delay Relay/700-PKT is a reliable and robust component for use in pneumatic control systems where precise timing is required. Its programmable delay function provides flexibility and precision, while its pneumatic operation makes it suitable for use in harsh environments. However, its limited delay times and the need for compressed air as a power source may be drawbacks for some applications.

If the need for a delay function in a pneumatic control system is critical and the delay times required are within the range of this relay, then it is a good choice. However, if more complex control functions or longer delay times are required, an electronic relay or other control component may be a better choice. Ultimately, the decision to purchase the Allen-Bradley 700-PH100A1 Pneumatic Delay Relay/700-PKT will depend on the specific requirements of the application and the resources available for implementation.
