Function

• The Low Level IOP module supports up 16 channels of temperature inputs.
• Any single channel can support either Thermocouple or Resistance Temperature Device (RTD) inputs.
  
• No external Process Manager FTA is required.

Notable Features

• TC and RTD operation
• Cold junction compensation
• 1 Second PV scanning with OTD protection
• Configurable OTD protection
