Description
The National Instruments FP-DI-300 Digital Input Module, with part number 777518-300, is a specialized component designed for FieldPoint systems that accommodates a wide voltage range of up to 250 V. This module is engineered for seamless installation, as it can be integrated into a powered terminal base without affecting the operation of other modules in the system.
Power is conveniently supplied to the FP-DI-300 directly from the terminal base, eliminating the need for separate power arrangements. The module boasts eight input channels, each with its own green status indicator, to effectively monitor digital signals. Furthermore, it offers the flexibility of connecting an external power supply to energize field devices.
The FP-DI-300 is compatible with sourcing output devices and features sinking inputs—meaning that it sinks current from the Vin terminal to the common (COM) terminal—enhancing its versatility in various applications. The module’s design includes optical isolators with current-limiting resistors for each input channel, which are referenced to Vin, ensuring reliable and safe operation.
Operational readiness is clearly indicated by the illumination of the READY indicator, which, along with the green POWER indicator, signifies that the module is functioning correctly and is in its normal operating mode. These indicators provide immediate visual feedback on the status of the module and its channels.
