National Instruments 785190-01 Voltage Input Module

National Instruments part number 785190-01 is the version of the NI-9264 Voltage Input Module with spring terminal connectors. These versatile connectors provide the module with safe and dependable connections under a variety of testing conditions. With 16 analog output channels and a string type DAC that has a resolution of 16 bits, the 785190-01 is an excellent choice for applications across both CompactRIO and CompactDAQ systems.

The push-in, spring-terminal wiring of the 785190-01 has a wire gauge of 0.14 mm² to 1.5 mm² (26 AWG to 16 AWG). Each wire is fastened using screw flanges and has a 10 mm (0. 394 in.) strip of insulation removed from the end, which facilitates stable and secure electrical connections. The screw flanges that keep the wires in place are fastened with a torque of 0.2 N · m (1.80 lb · in.).

The voltage output range of the 785190-01 spans from a minimum of ±10.35 volts to a maximum of ±10.65 volts, with a typical output of ±10.5 volts. At both startup and power-down, the voltage of the module is 0, enhancing safety for the user. The 785190-01 is capable of providing a maximum current drive of ±16 mA across all of its channels, and has an output impedance of 2.0 Ω.

The 785190-01 features 250 Vrms of channel-to-earth isolation voltage, and has no interference in channel-to-channel isolation. This robust voltage input module can withstand up to 3,000 Vrms, providing functionality in some of the most challenging conditions. Easy to place in various test setups, the 785190-01 weighs in at only 161 g (5.7 oz).
