Allen-Bradley 700-MB220-A1 Miniature Control Relay – 120V AC Coil, 2-Pole (2 NO), 10A, Fixed Terminal Base

The 700-MB220-A1 is a complete "Relay/Socket" unit. Unlike modular relays where the relay snaps into a separate base, the 700-M series often features integrated terminals or specialized pin-mountings for maximum vibration resistance. The "220" designation indicates the contact arrangement: 2 Normally Open (NO) and 2 Normally Closed (NC), or more commonly in this specific configuration, 2-Pole switching. The -A1 suffix confirms the coil is rated for standard 120V AC control power.
