The F2-02DAS-2 is a 2-channel analog output module that installs directly into any local, expansion, or remote I/O base of a DL205 PLC system (such as the D2-260 or D2-262 CPUs). The standout feature of this module is its total isolation, meaning that both channels are optically and galvanously isolated from each other as well as from the PLC backplane. It converts digital counts from the PLC CPU into a proportional analog voltage signal. It uses an internal microprocessor to monitor its own performance and features removable terminal blocks to make wiring and module replacement straightforward.

Product Parameters

Module Type: Analog Output
Number of Channels: 2 isolated channels

Isolation Voltage: 1500 V continuous channel-to-channel and channel-to-backplane
Output Impedance: Less than 0.5 Ohms
Maximum Output Current: 10 mA per channel
External Power Requirement: 24 VDC ( $\pm 10\%$ ) at 60 mA maximum (required to power the isolated loops)
Backplane Current Consumption: 90 mA at 5 VDC
Conversion Time: Less than 5 milliseconds for a full-scale change
Terminal Type: Removable 10-point screw terminal block

Product Advantages

A primary advantage of the F2-02DAS-2 is its Channel-to-Channel Isolation. In many industrial plants, different field devices are powered by different ground references; without isolation, this creates ground loops that distort analog signals. The F2-02DAS-2 eliminates this issue completely.

The High 16-Bit Resolution ensures extremely fine control over precision machinery, allowing for minute adjustments to motor speeds or valve openings. Because it belongs to the DL205 Platform, the module offers a highly cost-effective and compact form factor that maximizes I/O density in small control panels. Additionally, the Removable Terminal Block reduces downtime during maintenance since field wiring does not need to be disconnected wire-by-wire to change the module.

Important Considerations and Precautions

When setting up the F2-02DAS-2, you must configure the Internal Jumpers for your desired voltage range before inserting the module into the PLC base. Changing ranges while the module is powered can cause erratic output behavior or damage to connected equipment.

An External 24 VDC Power Supply is strictly required to run the analog circuitry; if this external power is lost, the module will stop updating its outputs and drop to 0V, regardless of what the PLC program dictates. Shielded Twisted-Pair Cable must be used for all analog output signals, and the shield should be grounded only at the PLC chassis end to prevent electromagnetic noise from distorting the high-resolution voltage signal. Finally, avoid running the low-voltage analog cables in the same conduit or wire duct as high-voltage AC motor lines to prevent inductive cross-talk.

Product Applications

The F2-02DAS-2 is ideally suited for applications where precise, noise-immune voltage control is necessary.

Variable Frequency Drive (VFD) Speed Control: Sending a 0-10V signal to control the speed of AC or DC motors in conveyor systems and pumps.
Proportional Valve Actuation: Modulating fluid or gas flow in chemical dosing or water treatment systems by precisely positioning proportional valves.
Servo Amp Interface: Driving analog command inputs on servo drives for localized positioning or tensioning control systems.
Chart Recorders and Panel Meters: Sending real-time process data from the PLC to remote analog displays or data logging stations.
Electro-Pneumatic Transducers: Controlling air pressure in automated assembly systems by interfacing with I/P transducers.
