When panel space is at a premium and you still need electronic reversing with diagnostics, the 3RM1302‑2AA04 delivers. It is a fully electronic reversing starter from the SIRIUS 3RM1 family that switches a 0.75 kW motor in a housing barely 22.5 mm wide — half the width of comparable electromechanical solutions — and talks IO‑Link for real‑time status, parameterisation and fault logging.

Electronic Reversing, Wear‑Free

• Solid‑state reversing contactor eliminates mechanical wear normally associated with forward/reverse switching.
• Integrated motor overload protection based on CLASS 10, electronic trip unit, adjustable from 0.4…2.0 A.
• Control signals (run‑left, run‑right, reset) via 24 V DC inputs or directly over IO‑Link, simplifying wiring to PLCs.

IO‑Link Communication

• On‑board IO‑Link interface (1 port) provides transparent access to all operating data, warnings and status bits.
• Parameterisation and firmware updates can be performed via IO‑Link masters without rewiring.
• Reduces system commissioning time: read motor current, switching counter, device temperature and pending alarms from the PLC.

Technical Specifications

Typical Applications

• Small conveyors that need to run forward and reverse for loading/unloading.
• Hoist or gate drives requiring compact reversing starters with overload protection.
• Machine tools where panel depth is limited and electronic diagnostics simplify maintenance.
