The 700S-PK620A1 from Allen Bradley functions as a master control safety relay that plays a critical role in safety applications. It offers a contact configuration consisting of 6 normally open contacts and 2 normally closed contacts for versatile control options. Rated for a maximum of 20 amps, this relay effectively handles significant current loads. The input voltage of 120V at 60 Hz makes it suitable for a wide range of industrial settings.
Designed for practical installation, this relay utilizes an open type DIN rail mount system. It incorporates screw-type terminals that can accommodate wire gauges between 18 AWG and 12 AWG, ensuring secure connections. The relay itself has 8 poles, which contributes to its status as a multi-functional control unit.
This relay operates using a mechanically held (latching) system, which prevents unintentional shifts in position and enhances stability during operation. The auxiliary contact type is bifurcated, allowing for reliable signal management. The minimum switching current is specified at 10 mA, enabling effective operation across various load conditions.
Moreover, the coil requires a pulse duration of only 20 ms to actuate, demonstrating efficient energization during operation. Temperature extremes are manageable, with this relay rated for functioning within an operating range down to -20 °C. It can be safely stored in environments as cold as -40 °C, making it suitable for use in diverse climates.
