This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
Micro800™ 4 Ch Universal Thermistor Input Module 3 Prevent Electrostatic Discharge WARNING Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module: Touch a grounded object to discharge static potential. Wear an approved wrist-strap grounding device. Do not touch connectors or pins on component boards. Do not touch circuit components inside the module.

Micro800™ 4 Ch Universal Thermistor Input Module 7 Configuration Tags This table shows the tags in the sample ladder program for configuration. Details are described in the sub-sections that follow. Register Data Type Comments S1_CFG_Trigger INT Transition from 0 to nonzero to trigger new config.
Micro800™ 4 Ch Universal Thermistor Input Module 8 New Config Trigger (S1_CFG_Trigger) This register is used as a trigger to the module that the configuration needs to be applied. You first modify all of the configuration parameters, and then trigger the new configuration. To trigger, the register must first be set to zero for a minimum of 300 ms. A non-zero value is then placed into the register to initiate the trigger.
Micro800™ 4 Ch Universal Thermistor Input Module 9 Configuring the Module The 2080sc-NTC is configured using 8 SINT configuration registers. The following table describes the module configuration registers. The default value of the configuration is represented by zeroes (0). A configuration error will be set if any of the values marked are passed. (Configuration Assembly) 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 MSB LSB 7 6 5 4 3 2 1076543210 Ch0 Channel Enable 0 Config.
Micro800™ 4 Ch Universal Thermistor Input Module 10 Data Format EU x1 This displays the measured readings in their natural integer form. Due to the measurement range and 16-bit data size, the highest resolution that can be displayed for resistance is 10 ohms. Temperatures will have two decimal places of resolution. For resistance, it will be in the range from 0 to 32767 which represents resistance in ohms divided by ten (0 to 327.67 k ohms).
Micro800™ 4 Ch Universal Thermistor Input Module 11 Temperature in Kelvin is determined by the following formula: ( ) B = User-supplied BETA parameter R0 = User-supplied resistance at room temperature (T0). T0 = (constant) Room temperature (25˚ C) in Kelvin (298.15). R = Measured resistance. After solving for T, it is then converted to Celsius: T - 273.15 Steinhart-Hart If the Equation is set to Steinhart-Hart, all three COEFF strings are used.
Micro800™ 4 Ch Universal Thermistor Input Module 12 The value is a signed, 16-bit integer. It represents temperature in degrees Celsius multiplied by 100 when the Equation is not set to Resistance. If the Equation is set to Resistance, the values represent ohms divided by 10. The Maximum cannot be not be equal to, or less than, the Minimum. An invalid configuration is set in that case. This format allows for temperature spans from +327.67C to -327.68C.
Micro800™ 4 Ch Universal Thermistor Input Module 13 The size of the string may be up to 16 characters. It is not necessary to terminate with NULL. A valid floating point number string is formed by a succession of: An optional plus or minus sign. A sequence of numeric digits, optionally containing a single decimal-point character. An optional exponent part, which itself consists on an 'e' or 'E' character followed by an optional sign and a sequence of digits.
