VIR GENERATOR UNIT U8794
Generation unit can be used for various simulation tests
instead of sensor output

Key Features

• As an inspection device of the ECU, it is ideal for generating
simulation signals of various sensors, inspection of electronic
parts, equipment maintenance
• DC voltage, DC current, and resistance simulation output possible
• In resistance generation, the voltage to be connected is measured,
the output current is calculated from the set resistance value, and
simulated output
• Used in combination with Memory HiCorder series
MR8740T (not available in other models)
• Insulation between each output channel and between channel and
chassis

Model No. (Order Code)

U8794For the MR8740-50
CE

Note: This module must be used with the Memory
HiCorder. Output cords are not included. Please
purchase them separately.
