IO-SA0400 Functions

RTD Conversion Enable/Disable

• For each channel, users can set RTD conversion to be enabled or disabled.
• For unused channels, users can make the conversion time short by setting them to disabled.

Temperature Detection Value

• The temperature detection value saves a converted Celsius and Fahrenheit value into memory.
  • This is down to the first decimal point × 10.
• The temperature detection value converts the temperature into a digital value:
  • 0 ~ 16,000
  • -192, ~ 16,191
  • -8,000 ~ 8,000
  • -8,192 ~ 8,192

Information for Operation Channels

• Information for channels under normal temperature conversion is displayed for each channel.
• If there is any disconnection error in the RTD conversion-enabled channel, the bit becomes 0.
• The bit for a disabled channel is 0.

Disconnection Detection Function

• There is a function to detect the disconnection of thermocouple and cable for each channel.
• If a disconnection is detected, the RTD module holds the temperature value before disconnection without further conversion.
  • In this case, the error code is displayed while the module LED flickers every 0.3 seconds.

Digital Output Setting

• Users can select the following value ranges for saving digital output values to buffer memory:
  • 0 ~ 16,000
  • -192 ~ 16,191
  • -8,000 ~ 8,000
  • -8,192 ~ 8,191

Minimum and Maximum Temperature Setting

• The minimum and maximum temperature value can be set by the user.
  • The RTD module converts the following temperature values into digital values:
    • -200°C ~ 600°C (-328°F ~ 1,112°F) → 0 ~ 16,000 (-8,000 ~ 8,000)
    • -50°C ~ 160°C (-58°F ~ 320°F) → 0 ~ 16,000 (-8,000 ~ 8,000)
• If a user inputs a minimum or maximum value, the RTD module converts the minimum value into 0 (-8,000) and the maximum value into 16,000 (8,000).
