The Siemens 405-4DAC-1 (also known as the F4-04DA-1) is a 4-channel analog current output module designed for the DL405 PLC family. This 405-4DAC-1 module converts digital control values into 4-20 mA current loop signals, enabling precise control of industrial field devices. Engineered for reliability, the 405-4DAC-1 seamlessly integrates into DL405-based control systems, providing 12-bit resolution and robust optical isolation for stable signal transmission in demanding automation environments.
Actuator, valve, and positioner control
Variable frequency drive (VFD) speed reference
Chart recorder and panel meter analog signal supply
Process control loops (flow, pressure, temperature)
PLC system analog output expansion and legacy system upgrades
Industry‑Standard Output – Delivers 4‑20 mA current loop signals for broad device compatibility
12‑Bit Resolution – Provides fine analog signal granularity for demanding control applications
Removable Terminal Block – Simplifies wiring, maintenance, and module replacement
Optical Isolation – Enhances noise immunity and protects the CPU from field wiring faults
Remote Base Support – Can be installed in any DL405 base slot, including expansion bases
Built‑in Diagnostics – Power and channel‑active status LEDs for rapid field troubleshooting
Digital‑to‑Analog Conversion – Transforms PLC digital values (0–4095) into proportional 4‑20 mA current signals
Multi‑Channel Simultaneous Output – Allows all four channels to be updated within a single PLC scan via channel selection logic
Field Device Driving – Provides stable current output to position valves, set drive speeds, and drive meters/recorders
System Expansion – Installs into any DL405 base slot (local or remote) without requiring a dedicated CPU slot
Q1: What analog output signal does the 405-4DAC-1 support?
A1: The 405-4DAC-1 supports a 4-20 mA current loop output only. It cannot be configured for 0‑20 mA or voltage outputs.
Q2: Does the 405-4DAC-1 require an external power supply?
A2: Yes, the 405-4DAC-1 requires an external +24 VDC supply to power its analog output circuits. It does not derive analog power from the backplane.
Q3: Can the 405-4DAC-1 be installed in an expansion base?
A3: Yes, the 405-4DAC-1 can be installed in any slot of any DL405 base, including both the main CPU base and expansion bases.
Q4: How many digital output points does the 405-4DAC-1 require?
A4: The 405-4DAC-1 requires 16 discrete output points in the CPU's image register (12 bits for data, 4 bits for channel selection).
Q5: What do the LED indicators on the 405-4DAC-1 mean?
A5: The 405-4DAC-1 features a PWR (green) LED indicating module power and per‑channel CH LEDs showing the energized state of each output channel for fast diagnostics.
