The overall system update rate is affected by other factors, such as the aggregate module update rate and software loop rate. To calculate the system update rate, visit ni.com/info and enter “systemrate.” Overview National Instruments cFP-DI-3xx devices are versatile digital input modules available for Compact FieldPoint systems. You can use these modules to monitor digital signals ranging from low-voltage levels up to 250 V. They are commonly used to monitor proximity and limit switches, pushbutton switches, thermostat outputs, relay closures, power circuits, and TTL devices. All the modules include onboard diagnostics to ensure trouble-free installation and maintenance. Digital Input Modules The cFP-DI-3xx modules provide built-in module-to-module isolation to protect your Compact FieldPoint system and controller or communication interface from high voltage levels. The cFP-DI-300, cFP-DI-301, and cFP-DI-304 modules use a common ground plane for all the input channels. Each channel on the cFP-DI-300, cFP-DI-301, and cFP-DI-304 modules includes current-limiting circuitry to prevent module damage when connected directly to a 24 VDC source. The cFP-DI-330 uses eight optically isolated input channels so that each digital input has a separate ground plane, and you can use each channel with a different voltage potential. Thus, you can connect one channel to a 5 VDC TTL signal and another signal on the same cFP-DI-330 module to a 250 VAC line voltage. Each channel on the cFP-DI-330 includes circuitry that limits the total current to 1.5 mA to prevent damaging the module. All channels on the cFP-DI-3xx modules feature LEDs that indicate the input state of each channel. The modules include an all-channel update rate of 1 kHz. Overall data throughput depends on software loop speeds and network speeds. Isolation The cFP-DI-3xx modules feature bank isolation with 2,300 Vrms of breakdown isolation. In addition, the cFP-DI-330 provides double insulation for up to 250 Vrms of operational isolation. You can safely use Compact FieldPoint with the cFP-CB-1 connector block in applications where hazardous voltages are present. These Compact FieldPoint modules do not have channel-to-channel isolation. Field I/O Connections Compact FieldPoint modules include a built-in power distribution bus that provides multiple power connections on the module. A field-wired power supply connected to the voltage (V) and common (C) terminals is internally connected to a power distribution bus that delivers additional breakout terminals for voltage supply (VSUP) and common (COM). These terminals offer a convenient way to distribute power to field devices that require external power.
