Description
The F4-04AD is a versatile analog input module integrated into the DirectLOGIC DL405 series, providing reliable signal acquisition for industrial automation applications. With four isolated input channels, the F4-04AD accepts both current and voltage signals, including standard industrial ranges such as 4-20 mA, 0-20 mA, 0-5 VDC, 0-10 VDC, 1-5 VDC, and ±5/±10 VDC. 

A key feature of the F4-04AD is its built-in broken transmitter or burnout detection functionality, which operates specifically in 4-20 mA mode with a detection threshold of approximately 1.25 mA. This allows the F4-04AD to identify sensor or wiring failures promptly, enhancing system reliability and reducing downtime. 

The F4-04AD module requires an external 24 VDC power supply for operation, ensuring stable performance in demanding industrial environments. Configuration and programming of the F4-04AD are accomplished using DirectSOFT programming software version 4.0 or later, allowing users to easily set up input ranges, scaling, and diagnostic parameters. 

In summary, the F4-04AD stands out as a dependable and flexible analog input module for the DL405 series. Its combination of multi-range signal support, high-resolution conversion, and advanced diagnostic features like burnout detection makes the F4-04AD an ideal choice for applications in process control, environmental monitoring, and equipment automation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does the burnout detection function work on the F4-04AD, and what is its threshold?
The burnout detection on the F4-04AD is active when the module is configured for 4-20 mA input mode. It monitors the input current and triggers a fault condition if the current drops below approximately 1.25 mA, indicating a broken transmitter or wiring issue. This status is then communicated to the PLC CPU for further action or annunciation.
What is the difference between the 16-bit and 32-bit modes for burnout indication on the F4-04AD?
The F4-04AD allows jumper selection between 16-bit mode and 32-bit mode for data and status handling. In 16-bit mode, a single multiplexed bit is used to indicate burnout status across channels (as detailed in manual page 3-15). In 32-bit mode, each channel has its own dedicated bit for burnout indication, providing more granular fault reporting (refer to manual page 3-18).
What input signal ranges are supported by the F4-04AD module?
The F4-04AD supports a wide variety of analog input ranges for both current and voltage signals. Current inputs can be configured for 4-20 mA or 0-20 mA. Voltage inputs accept 0-5 VDC, 0-10 VDC, 1-5 VDC, ±5 VDC, and ±10 VDC. This flexibility allows the F4-04AD to interface with most standard industrial sensors and transmitters.
What is required to power and program the F4-04AD module?
The F4-04AD requires an external 24 VDC power supply for proper operation. Configuration, scaling, and diagnostics are performed using DirectSOFT programming software version 4.0 or later. The module is designed as a sinking analog input type with non-isolated input commons, simplifying installation and integration into DL405 PLC systems.
