NI-9203 Getting Started

Connector Types

The NI-9203 has more than one connector type: NI-9203 with screw terminal and NI-9203 with spring terminal. Unless the connector type is specified, NI-9203 refers to all connector types.

NI-9203 Block Diagram

The input signals are buffered, conditioned, and sampled by a single 16-bit ADC. The module protects each channel from overvoltages. Refer to the Specifications section for information about overvoltage protection.

Each channel has an AI terminal to which you can connect a current signal. The NI-9203 also has a common terminal, COM, that is internally connected to the isolated ground reference of the module.

Connecting Single-Ended Current Signals

You can connect single-ended current signals to the NI-9203.

Note You must use 2-wire ferrules to create a secure connection when connecting more than one wire to a single terminal on the NI-9203.

Conformal Coating

The NI-9203 is available with conformal coating for additional protection in corrosive and condensing environments, including environments with molds and dust.

In addition to the environmental specifications listed in the NI-9203 Safety, Environmental, and Regulatory Information, the NI-9203 with conformal coating meets the following specification for the device temperature range. To meet this specification, you must follow the appropriate setup requirements for condensing environments. Refer to Conformal Coating and NI RIO Products for more information about conformal coating and the setup requirements for condensing environments.

Operating humidity (IEC 60068-2-30 Test Db) 80 to 100% RH, condensing
