The Molex SST‑SR4‑CLX‑RLL is a high‑performance communication module designed by Molex for interfacing ControlLogix systems with Modbus serial networks. It provides protocol translation and data exchange between Modbus Master or Slave and Allen‑Bradley systems. The module supports both Modbus RTU and ASCII modes on each of its four serial channels.
Each channel operates between 110 to 115,200 bps, and the module supports both RS‑232 and RS‑485 electrical interfaces. It mounts as a plug‑in module in a ControlLogix rack and draws power via its backplane. The SST‑SR4‑CLX‑RLL weighs approximately 1.32 kg, and includes LED indicators for power, activity, and fault status.
