EL2624

EL2624 is a Beckhoff terminal in the EL EtherCAT Terminals series. It uses relay-output connection technology to switch external circuits and provides four make contacts as its outputs. The process image occupies four output bits, allowing the controller to address the four channels individually. It is intended for ohmic loads and has a nominal voltage rating of 125 V AC or 30 V DC. Each channel supports an ohmic switching current of 0.5 A AC or 2 A DC. The minimum permitted load is 10 µA at 10 mV DC, which establishes the lowest supported switching level.

The relays have a minimum electrical life of 2 × 10⁵ cycles when switching 1 A at 30 V DC. Their minimum mechanical life is 1 × 10⁸ cycles. The terminal receives its operating power through the E-bus. Its power contacts support 10 A and loop the L and N conductors through the terminal to distribute power along the terminal assembly.

The polycarbonate housing provides electrical insulation and mechanical protection for the internal components. The terminal mounts on a 35 mm DIN rail in accordance with EN 60715, supporting installation in standard control cabinets. Its IP20 protection class protects against finger contact and solid objects larger than 12.5 mm but does not provide water protection.
