1 / 5 page Analog Output Modules for Compact FieldPoint Overview 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. Smart I/O Modules 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. 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. 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. 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. 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 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) • 8 power connections for field devices or current loops (VSUP) The cFP-AO-210 has: • 8 voltage output terminals (VOUT) • 16 common terminals (COM) • 8 power connections for field devices or current loops (VSUP) • 8 voltage or current outputs • 0 to 10 V • 0 to 20, 4 to 20 mA • 12-bit resolution • Output ranges software-configurable per channel • 2,300 Vrms bank isolation for transient overvoltage protection • Hot-swappable with autoconfiguration • -40 to 70 °C operating range NI cFP-AO-200, NI cFP-AO-210 Module Input Channels Resolution Output Types Output Ranges (Software Configurable per Channel) All Channel Update Rate1 cFP-AO-200 8 12 bits Current 0 to 20 mA, 4 to 20 mA 200 Hz cFP-AO-210 8 12 bits Voltage 0 to 10 V (up to 10 mA/ch) 200 Hz 1 The 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.” |
