EUCHNER ESM-BT411 Time-Delay Safety Relay, 2 + 2 Contacts
The EUCHNER ESM-BT411 (order no. 090819) is the balanced version of the ESM-BT time-delay range. It has two instantaneous and two time-delayed safety contacts. This fits applications that need two circuits cut immediately, such as control enables, and two cut after a set run-down time, such as main contactors on drives with braking. It runs on 24 V AC/DC and reaches PL e to EN ISO 13849-1.
2 Instantaneous + 2 Delayed Contacts
The two delayed contacts open after an adjustable delay of 1 to 30 seconds, set with a potentiometer. The non-delayed contacts are rated Category 4 / PL e (PFHd 4.22 x 10⁻⁸). The delayed contacts are rated Category 3 / PL e (PFHd 8.84 x 10⁻⁸).
Fast Response and High Current Capacity
The response delay is max. 20 ms, and the cumulative current is max. 15 A across all contacts. It supports single-channel or dual-channel control, and LEDs show the status.
