Siemens SIMATIC ET 200SP DQ 8×24 V DC/0.5 A HF – a compact eight-channel digital output module designed for industrial programmable logic controller (PLC) systems, process automation and electrical equipment control circuits. The module has eight 24 V DC PNP transistor outputs, each rated for a nominal load current of 0.5 A, with a maximum total output current of 4 A. The High Feature version offers extended diagnostic capabilities, individual channel status monitoring, short-circuit and wire-break detection, supply voltage monitoring and support for isochronous operation. The 15 mm wide design allows efficient use of space in automation cabinets. The module is designed for installation in the SIMATIC ET 200SP system using an A0-type BaseUnit and can be configured in STEP 7, TIA Portal and PCS 7 environments.

Key point:
In an industrial automation system, the PLC processes signals and makes control decisions, but output modules are required to switch physical loads. This eight-channel digital output module allows control of 24 V DC actuator circuits such as interface relays, contactor coils, solenoid valves, signalling indicators and other compatible devices. High Feature functionality not only allows ON/OFF commands to be transmitted, but also enables diagnostics of individual channel faults, power supply monitoring and faster troubleshooting of automation-system faults.

⚡ Spark: Phase, how does this eight-output module differ from a conventional relay module? Can I use it to control eight electrical devices directly?

⚙ Phase: This module uses PNP transistor outputs rather than mechanical relays. When a channel is switched on, it supplies 24 V DC to a load whose current does not exceed 0.5 A. This is very convenient for controlling interface relays, contactor coils, solenoid valves and signalling circuits. The High Feature version additionally monitors output states and detects short circuits and wire breaks. If 230 V equipment or higher-power loads need to be controlled, suitable intermediate switching devices are used.

What are the benefits of this digital output module?
One 15 mm wide module can control eight independent 24 V DC actuator circuits. PNP transistor outputs provide fast and precise signal switching, while High Feature diagnostics help identify the causes of short circuits, wire breaks and power-supply faults. Integration with SIMATIC ET 200SP and STEP 7 / TIA Portal allows the module to be used in distributed I/O control architectures, reducing wiring and saving space in automation cabinets.

A SIMATIC ET 200SP distributed I/O system is used on a production line. Four 24 V DC solenoid valves, two interface relays and two signalling indicators need to be controlled. An eight-channel digital output module is installed in the ET 200SP station. The first four outputs are assigned to the solenoid valves, the fifth and sixth to the interface relays, and the seventh and eighth to the signalling circuits. The PLC program sends separate ON and OFF commands to each channel. If a short circuit or wire break occurs in one circuit, the diagnostic system can register the fault on the corresponding channel and provide information to the operator. In this way, one compact module can organise the control of several actuators and maintenance diagnostics.

• Professional installation. Connection and commissioning of the module should be performed by qualified electrical and automation specialists.
• Power supply. A 24 V DC supply is used, with an allowable range of 19.2–28.8 V DC.
• BaseUnit. The module is installed in a compatible A0-type BaseUnit.
• Output type. PNP outputs supply a positive potential, therefore load wiring must be selected for source-type outputs.
• Channel load. The load current of each output must not exceed 0.5 A.
• Total load. The sum of all output currents must not exceed 4 A.
• Inductive loads. The specified switching-frequency and overvoltage-limiting requirements apply when controlling electromagnetic coils.
• Power-circuit protection. Properly selected power supplies and protective devices must be used.
• Cable connection. 1-wire and 2-wire circuits are connected through BU A0; AUX terminals or potential-distribution components are used to distribute additional potentials.
• Diagnostics. Channel diagnostic parameters are configured in the PLC according to the equipment-control requirements.
• Cable routing. Signal and power circuits should be routed to minimise the effects of electromagnetic interference.
• Temperature. An FS07 module installed horizontally can be used from −30 to +60 °C, and vertically up to +50 °C.
• Galvanic isolation. The outputs are not galvanically isolated from each other.
• Functional safety. The standard DQ module is not used as a certified safety output for emergency stopping or other functions requiring an F-DQ module.
• Fault check. After installation, the switching signals, load operation and diagnostic indicator states of each channel should be checked.
• Maintenance. Electrical contacts, supply voltage, cable condition and PLC diagnostic records should be checked periodically.

⚡ Phase tip:
When selecting a digital output module, it is essential to distinguish the current of one channel from the total module load. This module has eight 0.5 A outputs, but this does not mean that all 4 A can be supplied through a single output. Each channel has its own 0.5 A limit. It is also important to note that these are PNP outputs – they supply a positive 24 V DC potential to the load. When controlling 230 V devices, suitable interface relays or contactors are used. The High Feature module is particularly useful where it is important to see not only the output command but also diagnostic information about a fault in the connected circuit.

Quick selection guide

⚡ Spark: What does DQ 8×24 V DC/0.5 A HF mean?
⚙ Phase: DQ means digital outputs, 8 is the number of channels, 24 V DC is the rated output voltage, 0.5 A is the current per channel, and HF identifies the High Feature version with extended diagnostics and additional control functions.

⚡ Spark: Is this an input or output module?
⚙ Phase: It is an eight-channel digital output module. It transfers PLC control commands to external loads rather than measuring sensor signals like a digital input module.

⚡ Spark: What does PNP output mean?
⚙ Phase: When switched on, a PNP current-sourcing output supplies a positive supply potential to the load. The load is connected between the controlled output and the common 0 V potential according to the intended wiring scheme.

⚡ Spark: Can each channel control a 4 A load?
⚙ Phase: No. The nominal current of one channel is 0.5 A. 4 A is the maximum total current of all eight outputs.
