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
The cFP-AO-210 includes eight 0 to 10 V output channels, generated
with a 12-bit DAC. Each channel provides a voltage source capable
of supplying up to 1 mA. You can obtain up to 10 mA by powering the
cFP-AO-210 with an optional external power supply of 15 to 30 VDC.
National Instruments cFP-AO-2xx devices are versatile analog output
modules for Compact FieldPoint that you can use to control valves,
gauges, and other industrial actuators. All modules include overranging
and onboard diagnostics to ensure trouble-free installation and
maintenance. The NI cFP-AO-2xx modules come with NIST-traceable
calibration certificates, ensuring accurate and reliable analog control.
Isolation
The cFP-AO-2xx modules feature optical bank isolation with 2,300 Vrms
of breakdown isolation. They do not have channel-to-channel isolation.
Smart I/O Modules
Field I/O Connections
With cFP-AO-2xx modules, you can directly connect to your industrial
actuators or units under test and get high-accuracy control. The
I/O modules calibrate and scale engineering units to sensor signals,
as well as perform self-diagnostics to detect problems with the module
or with the wiring such as open current loops. With cFP-AO-2xx modules,
your software application writes an engineering value to the I/O module,
eliminating the error-prone step of converting voltage or current to
binary values. The cFP-AO-2xx modules have an update rate of 200 Hz.
Overall data throughput to the controller or PC depends on the software
loop speeds and the network speeds.
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 offers additional breakout
terminals for voltage supply (VSUP) and common (COM). These terminals
deliver a convenient way to distribute power to field devices that require
external power.
The cFP-AO-200 has:
• 8 current output terminals (IOUT
)
• 16 common terminals (COM)
The cFP-AO-200 includes eight 0 to 20 mA or 4 to 20 mA analog
output channels, generated with a 12-bit DAC. Each output channel
features a monitoring circuit and LED indicator for open current loop
detection. The cFP-AO-200 requires an external power supply that
provides 5 to 24 VDC.
• 8 power connections for field devices or current loops (VSUP
)
The cFP-AO-210 has:
