NI-9227  781099-01 C Series Current Input Module 

The NI 9227 module has four 2-terminal separable screw-terminal connectors that give associations with 4 at the same time examined, secluded simple information channels. The NI 9227 simple information channels are skimming regarding earth ground and each other, and are differential analog inputs. The approaching simple signal on each channel is molded, cushioned, and inspected by a 24-bit Delta-Sigma ADC. Every channel gives an autonomous signal way and ADC, empowering users to test every one of the four channels at the same time. The NI 9227 consumes power up to 730 mW when in active usage, while it consumes 50 μW maximum when in sleep mode.

The user can connect ground-referenced or coasting current sources to the NI 9227. Interface the positive side of the present source to the AI+ terminal and associate the negative side of the present source to the AI-terminal. If the user makes a ground-referenced association between the present source and the NI 9227, they should ensure the voltage on the AI+ and AI-associations are in the channel-to-earth security voltage area to guarantee legitimate activity of the NI 9227. The device weighs 5.1 oz. It has a recommended operating temperature range of -40 to 70 °C.
