RLCONV – Ringline System (non I.S with integrated prestart)

RLCONV – Ringline System (non I.S with integrated prestart)

Features

  • Up to 40 emergency stop points and 40 field device inputs (digital/analog)
  • Integrated pre-start alarm system with visual/audible alerts
  • Ethernet/IP & Modbus RTU communication for seamless PLC/SCADA integration
  • Dual-channel safety logic with redundant microprocessors
  • Built-in stoppage history (last 10 events) for diagnostics
  • Supports condition monitoring (e.g., earth fault, belt tracking, bearing temp)
  • Compact footprint, 24VDC powered, and compliant with AS/NZS 4024
  • Simple, robust and functional
  • 4 km radius coverage over two wires
  • Dedicated local display option with stoppage history
  • Will operate with or without a PLC

Applications

Perfect for mining, materials handling, and industrial automation, the RLCONV enhances safety and visibility across complex systems—whether you’re managing a single conveyor or an entire plant.

Traditional stop chains sprawl across terminal strips and give zero context. RLCONV replaces that mess with a single shielded pair, stores stop history, pushes diagnostics to SCADA and lets you add or move transmitters without touching PLC code. The result is faster installs, quicker fault-finding and safety integrity proven to CAT3 / SIL2 / PL d equivalence.

RLCONV can be used on any conveyor or machine that requires a Pre Start Alarm and / or a distributed network of emergency stop switches or devices to be interlocked to a control system in a failsafe manner. Ringline has a long history of reliable performance as an emergency stop signal line and remote whole-current isolation controller for conveyors in harsh environments. Any Ringline transmitters that are not allocated to the safety function can be used to provide chute full, belt tracking, bearing temperature monitoring or any other remote PLC input requirement.
