EUCHNER ESM-BA303 Safety Relay for 230 V AC, 3 + 1 Contacts
The EUCHNER ESM-BA303 (order no. 087413) is the 230 V AC version of the ESM-BA3 basic module, made for control panels that run on European mains voltage. It is supplied directly at 230 V AC, while the input circuit (S11–S14) runs at a safe 24 V DC control voltage. It reaches Category 4 / PL e to EN ISO 13849-1.
Contact Configuration
It has three redundant, positively driven safety contacts (13/14, 23/24, 33/34) and one auxiliary monitoring contact (41/42). The safety contacts are rated AC-12 250 V / 8 A, AC-15 250 V / 3 A and DC-13 24 V / 3 A. The cumulative current across all contacts is max. 15 A.
Input Monitoring
It supports single-channel or dual-channel control, with short-circuit and earth-fault monitoring. LEDs show the relay status, and control cables can run up to 1,000 m (0.75 mm²).
