700-PPTB11

The part number 700-PPTB11 by Allen Bradley is categorized as a pneumatic time-delay relay, making it suitable for applications requiring controlled timing. This unit operates within a coil voltage spectrum of 110 to 115 volts AC or 120 volts AC, with a frequency of either 50 or 60 Hz. The relay is specifically manufactured with a contact configuration that includes one normally open (NO) and one normally closed (NC) contact, providing versatility for various control circuits.

Designed to handle a maximum contact carrying capacity of 10 A, the 700-PPTB11 can manage significant loads while ensuring reliability in performance. The time-delay feature is adjustable, with a range extending from 0.1 to 60 seconds, allowing precise control over operational timing. With an enclosure classified as NEMA Open Type, it is well-suited for environments where ventilation is not a concern.

Totaling two time-delay contacts, this relay's mounting style is top-mounted, simplifying installation into existing systems. The terminals are screw type, ensuring secure and stable connections during operation. When powered up, the relay requires a coil pick-up power of 30 VA and operates at a sealed power of 5 VA post pick-up. Furthermore, it is capable of switching voltages up to a maximum of 600 V AC, making it functional in high-voltage applications. The contacts of this relay are composed of silver alloy, enhancing conductivity and durability.

For quality assurance, the 700-PPTB11 carries UL Listing and CSA Certification, confirming that it meets stringent safety and performance standards.
