The SR3NET01BD is an Ethernet communication interface for the Schneider Electric Zelio Logic SR3 series smart relays (24 V DC models). It adds a 10/100BASE-T port via an RJ45 connector, with two LEDs for link/activity and module status.
Mounted on the front of an SR3 smart relay, the module occupies no additional DIN rail space. Terminal block wiring accepts 0.25–2.5 mm² solid or flexible cable (AWG 24–14) with a tightening torque of 0.5 N·m. Pollution degree 2 per IEC 61131-2 means it is suitable for typical control panel environments without conductive contamination. Operating temperature range is –20 to 55 °C (IEC 60068-2-1/2-2) with a 40 °C derated limit; storage range –40 to 70 °C. The module is rated IP20 at the terminal block and IP40 on the front panel per IEC 60529.
Compliance & immunity
The module conforms to the EMC directive via IEC 61000-6-2 (industrial immunity), IEC 61000-6-3/4 (emission), and IEC 61131-2 zone B. Radiated/conducted emissions meet Class B of EN 55022-11 group 1. Transient/burst immunity is Level 3 per IEC 61000-4-4, surge per IEC 61000-4-5, and ESD per IEC 61000-4-2 Level 3. Vibration (IEC 60068-2-6 Fc) and shock (IEC 60068-2-27 Ea) testing is covered. The module operates at altitudes up to 2000 m and withstands 95% relative humidity without condensation.
