Flex Modules—High Density I/O Specifications

Four Universal Inputs (Control Loops, Auxiliary Input)

• Thermocouple: grounded or ungrounded sensors, greater than

20MΩ input impedance, 2kΩ source resistance max.

• RTD: 2-wire, platinum, 100Ω and 1000Ω at 32°F (0°C) calibration to

DIN curve (0.00385Ω/Ω/°C)

• Process: 0-20mA at 100Ω, or 0-10VDC, 0-50mVDC at 20kΩ input

impedance; scalable

• Potentiometer: 0 to 1,200Ω

• Inverse scaling

Four Thermistor Inputs (Control Loops, Auxiliary Input)

• 0 to 40kΩ, 0 to 20kΩ, 0 to 10kΩ, 0 to 5kΩ

• 2.252kΩ and 10kΩ base at 77°F (25°C)

• Preprogrammed Steinhart-Hart coefficients for Alpha Techniques

(A curve 2.252k and 10k, C curve 10k), BetaTHERM (2.2K3A, 10K3A

and 10K4A) and YSI (004, 016 and 006)

• User-settable Steinhart-Hart coefficients for other thermistors
