1The all-channel update rate refers to the time the module takes to sample all channels. 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.
