Product Analysis: Panasonic FP2-DA4 Analog Output Unit
The FP2-DA4 is a high-precision Analog Output Module for the Panasonic FP2 Modular PLC series. Designed to extend the capabilities of the FP2/FP2SH CPUs, this module provides four independent channels that convert digital PLC data into analog signals. It is an essential component for controlling Proportional Valves, Variable Frequency Drives (VFDs), and other actuators that require a continuous voltage or current signal for precise industrial process regulation.
High-Resolution Signal Conversion
The FP2-DA4 features a high-resolution conversion architecture (up to 16-bit depending on configuration), ensuring that control signals are generated with the accuracy required for delicate chemical dosing or precision speed synchronization. Each of the four channels can be independently configured for Voltage (0-10V) or Current (4-20mA) outputs. This versatility allows a single module to handle diverse field devices, reducing the need for multiple specialized expansion cards.
Key Technical Characteristics
- Part Number: FP2-DA4 (AFP2401).
- Output Channels: 4 Channels.
- Output Ranges: 0 to 5V, 0 to 10V, +/- 10V, 0 to 20mA, 4 to 20mA.

Modular Reliability and System Integration
As part of the FP2 modular ecosystem, the FP2-DA4 is designed for easy «hot-swapping» and rapid panel installation. It features integrated self-diagnostic LEDs that indicate the status of the external 24V supply and internal conversion logic. The module occupies a single slot on the FP2 backplane, appearing as a group of I/O registers in the FPWIN Pro or FPWIN GR programming environments, making it straightforward to scale your system’s output capacity.
| Feature | Value |
| External Power Supply | 24V DC |
| Internal Current Consumption | Approx. 120 mA |
| Accuracy | +/- 0.3% of Full Scale |
Technical Note
When wiring the FP2-DA4, ensure that shielded twisted-pair cables are used for all analog signal runs to minimize the impact of electromagnetic noise. The shielding should be grounded at the PLC end only to avoid ground loops that can degrade signal accuracy.
