The RIO4000 is the RTD measure and simulate module for the Meriam MFT 4000 Series Multi-Function Tester. The module accurately measures or simulates the resistance of 22 different RTD sensor types with nominal resistance to 4000 Ω. 2-, 3-, and 4-wire RTD Measurement for various RTD types; platinum, copper, nickel or iron. The module can simulate temperature to all conventional or smart temperature transmitters and signal conditioners.

The RIO4000 is available with the required RTD starter kit (ZA37063), which includes a measure cable (to connect the RIO4000 module to RTD wires/transmitter terminals), RTD mating connector (to connect RTD), and 2-wire simulation cable.

• Simulates temperature to various transmitters, including conventional, smart, and signal conditioners
• Supports various RTD types including platinum, copper, nickel, and iron
• User-selectable temperature units including °C, °F, K, and °R
