EL2652
by Beckhoff
The Beckhoff EL2652 module, belonging to the EL EtherCAT Terminals series, is a robust relay output terminal designed for industrial automation applications. Featuring 2 change-over contacts and relay output connection technology, it supports a maximum switching voltage of 250 V AC and 300 V DC. The EL2652 serves as a compact interface for controlling and isolating high-voltage AC or DC loads, providing precise switching functions for external devices or circuits in demanding factory environments.
This terminal operates on a nominal voltage of 230 V AC with a maximum ohmic switching current of 3 A at 30 V DC and 1 A at 40 V DC, while at the upper DC limit of 300 V the rating is 0.15 A. For UL-compliant applications, it handles 1 A at 230 V AC. It delivers a minimum load current of 100 mA at 12 V and a maximum switching frequency of 6 operations/min. The EL2652 demonstrates exceptional longevity with mechanical endurance of 5×10^6 cycles and electrical endurance of 1×10^6 cycles (1 A, 250 VAC), and incorporates a special reverse switching capability for enhanced flexibility in process control.
Designed for reliability and efficiency, the EL2652 draws only 180 mA from the E-bus without consuming field power. Its electrical insulation between E-bus and field side is validated by a test voltage of 1.5 kV and rated surge protection up to 2.5 kV, meeting overvoltage category III requirements. Operating across a temperature range of 0 to 55°C and relative humidity up to 95% non-condensing, it is approved by CE, UL, and DNV GL. The combination of high endurance, precise switching characteristics, and rigorous safety ratings makes the EL2652 an ideal choice for automation systems seeking reliable, long-term performance.
