Overview
The Allen-Bradley 700DC-PK400Z24 is a DC-operated master control relay from the Bulletin 700DC series, engineered for reliable switching in industrial control circuits. This relay features a 24 VDC coil with 4 normally open contacts and an open enclosure type. The 700DC product line consists of direct-drive industrial relays offering switching solutions ranging from 200 mA in low-energy circuits to 35 A in heavy-duty circuits.
Key Features
- 4 normally open contacts with zero normally closed contacts
- Double-break and bifurcated contact cartridge design rated at 10 Amps
- Can be accessorized with optional devices such as time-delayed contacts, NEMA enclosures, or mechanical latches
- 24V DC coil voltage for standard control applications
- Open type rail-mount enclosure
Technical Specifications
The relay provides 4 N.O. contacts with a 10 Amp AC contact rating and operates at 24V DC. The unit is designed for mounting on control panels and machine systems requiring master control functions.
