The Siemens 405-4DAC‑2 is a 4‑channel analog output module for the DL405 and DirectLOGIC 405 PLC families, engineered to convert digital control commands into precise analog signals. The 405-4DAC‑2 provides isolated current outputs (0‑20 mA, 4‑20 mA) or voltage outputs (0‑5 V, 0‑10 V, ±5 V, ±10 V) with 12‑bit resolution, enabling accurate modulation of valves, actuators, drives, and recorders. Housed in a standard base form factor, the 405-4DAC‑2 installs in any slot of a DL405 base without additional cabling. Built‑in diagnostics and removable terminal blocks simplify installation and maintenance, making it an efficient choice for legacy system upgrades or new automation projects requiring multi‑channel analog control.
Multi‑Range Flexibility – Four channels independently configurable for current or voltage outputs with per‑channel jumpers
Galvanic Isolation – Optical isolation between backplane and field side improves noise immunity and protects the CPU
Diagnostic LEDs – Power (PWR) and channel‑active (CH) indicators for rapid fault identification
Removable Terminal Block – Simplifies module replacement and field wiring without re‑termination
No External Burden Resistors – Direct connection to actuators and recorders minimizes external components
Wide Operating Range – Reliable 0°C to 60°C operation in typical industrial environments
Digital‑to‑Analog Conversion – Transforms PLC digital values into 0‑20 mA, 4‑20 mA, 0‑5 V, 0‑10 V, ±5 V, or ±10 V analog signals
Multi‑Channel Simultaneous Output – All four channels can be updated in a single CPU scan
Field Device Driving – Provides sufficient current/voltage to position valves, set drive speeds, and drive meters
System Expansion – Plugs into any DL405 base slot, including expansion bases, to increase analog output capacity without changing the CPU
Fault Monitoring – Onboard status LEDs enable quick field troubleshooting, reducing maintenance downtime
Q1: What analog output signal ranges does the 405-4DAC-2 support?
A1: The 405-4DAC-2 supports current outputs of 0‑20 mA and 4‑20 mA, and voltage outputs of 0‑5 VDC, 0‑10 VDC, ±5 VDC, and ±10 VDC, per‑channel configurable via jumpers.
Q2: Does the 405-4DAC-2 require an external power supply?
A2: Yes, the 405-4DAC-2 requires an external +24 VDC supply (±10%) to power its analog output circuits. It does not draw power from the DL405 backplane for analog generation.
Q3: Can I install the 405-4DAC-2 in an expansion base?
A3: Yes, the 405-4DAC-2 can be installed in any slot of any DL405 base, including both the main CPU base and expansion bases, with the same electrical performance.
Q4: What resolution does the 405-4DAC-2 offer?
A4: The 405-4DAC-2 provides 12‑bit resolution (1 part in 4096), delivering fine analog signal granularity suitable for precise process control applications.
Q5: What do the LED indicators on the 405-4DAC-2 mean?
A5: The 405-4DAC-2 features a PWR (green) LED indicating module power and channel‑active (CH) LEDs showing the energized state of each output channel, aiding in rapid field diagnostics.
