Panel installation compatible! Standard models and insulation/wide temperature compatible models are available.
The ULI-224TH/THC is an industrial converter that converts RS-232 signals to RS-422/485, achieving high-speed communication of up to 460.8kbps and long-distance transmission of up to 1.2km. Both models feature a robust metal housing suitable for panel mounting and support industrial protocols such as Modbus RTU. The ULI-224TH is a non-isolated version with a standard temperature range (0 to +70°C), making it ideal for relatively stable environments like control panels. On the other hand, the ULI-224THC supports **2kV optical isolation and a wide temperature range (-40 to +80°C)**, making it perfect for harsh industrial environments or locations requiring isolation protection. Both models require an external power supply (10 to 30VDC).
