S30810-Q2929-X SIEMENS

The ‌SIEMENS Output Module‌ is a core on-site execution driving component for Siemens SIMATIC industrial automation systems, responsible for converting the digital logic control signals issued by the central processing unit into switch signals that can directly drive on-site actuators. It covers two main categories: digital output modules and relay output modules, and is fully compatible with SIMATIC S7 series PLCs, ET 200SP distributed I/O systems and PROFINET/PROFIBUS bus architectures. As the final execution interface between the control system and on-site equipment, it undertakes various switch control tasks such as motor start and stop, solenoid valve action, indicator light status indication and contactor pull-in.

Core Product Parameters

• ‌Channel configuration‌: 4/8/16/32 independent output channels optional, supporting group potential division to adapt to different voltage level loads
• ‌Output type‌: Transistor DC output (24V DC), relay contact output (24V DC~230V AC), and triac AC output three mainstream types for selection
• ‌Load capacity‌: Single-channel maximum current from 0.5A for transistor models to 5A for relay models, and the maximum total current of the whole module does not exceed 10A
• ‌Response performance‌: Transistor output maximum response delay ≤0.1ms, relay output action time ≤10ms, meeting different control speed requirements
• ‌Isolation performance‌: 500V~2000V AC galvanic isolation between channels and backplane bus, meeting IEC 61000 EMC anti-interference standards
• ‌Diagnosis function‌: Natively supports channel-level over-current protection, load power loss detection, short-circuit alarm and fault status feedback
• ‌Electrical life‌: Transistor output no mechanical wear, service life ≥10 years; relay model mechanical life up to 10 million operations
• ‌Operating environment‌: Industrial wide temperature range from -25°C to +60°C, IP20 protection rating, supporting hot-swap under live backplane bus

Key Product Advantages

1. ‌Full series type coverage‌: Transistor, relay and triac output types are available, which can directly adapt to DC low-speed switch, DC high-speed pulse and AC load scenarios without adding extra intermediate relays
2. ‌High safety and reliability‌: Built-in over-current and short-circuit protection, which can automatically cut off the faulty channel when the on-site load is abnormal, avoiding the fault spreading to the control system side
3. ‌High space utilization‌: Ultra-narrow 15mm modular design for ET 200SP series, which can arrange more output channels in limited cabinet space, greatly improving cabinet space utilization
4. ‌Efficient engineering maintenance‌: All configuration, channel diagnosis and fault location can be completed in TIA Portal, and hot-swap replacement can be realized without rewiring, which greatly reduces maintenance downtime
5. ‌Long industrial service life‌: Industrial-grade components and reinforced insulation design, mean time between failures (MTBF) exceeds 600,000 hours, which can stably operate in harsh industrial scenarios such as frequent switch actions and strong vibration

Important Notes

• Before wiring, confirm that the output voltage level of the module is completely consistent with the power supply specification of the on-site actuator, and it is strictly forbidden to connect 230V AC load to the 24V DC transistor output module
• The actual operating current of a single channel must not exceed the rated output current specified by the module, and the total load current of all channels must not exceed the maximum total current limit of the module
• For inductive loads such as contactors and solenoid valves, it is necessary to add freewheeling diodes at the load side of the DC output, and add RC absorption loops at the AC output side to suppress the instantaneous counter electromotive force
• Do not hot-swap the output module when the on-site load is powered on, otherwise the instantaneous surge current may burn out the output drive circuit
• For relay output models with frequent actions, regularly check the contact wear every 12 months. When the action frequency exceeds the rated service life, replace the module in time to avoid poor contact
