National Instruments cFP-DI-330 Digital Input Module for Compact FieldPoint

The cFP-DI-330 (Part number: 777318-330) is a Digital Module to input data for Compact FieldPoint applications. This module is manufactured by National Instruments. The device has 8 DI channels. The module has universal inputs. This feature enables the device to operate with multiple voltage ranges. The voltage range is from 5 to 250 volts for both AC and DC. The device is specially developed for sinking and sourcing applications. The module is also compatible with power sensing applications.

The NI cFP-DI-330 has the onboard feature of module-to-module isolation. This feature helps provide protection against high voltage levels and keeps the communication or controller interface safe. Each channel is attuned with 5 VDC to 48 VDC signals. They are also compatible with AC signals up to 240 VAC. The NI cFP-DI-330 can be installed easily. It is mounted on the backplane of a Compact FieldPoint device. It also helps provide operating power to the module. The NI cFP-DI-330 is equipped with eight current-limited universal inputs. These channels are structured with bi-directional optical isolators. All channels are equipped with two interchangeable signal inputs. These signal inputs are also referred to as INa and INb. 

The NI cFP-DI-330 has 2 indicators referred to as Green POWER and READY indicators. It requires 200 mW from a network module. The signal current directs from the in house circuit for input when a voltage is applied across any of the terminals from Ina or INb. The optical isolator then becomes operational. It registers as an ON condition. The current-limiting circuitry bounds the course of current to 1.5 mA.
