Product Description

The Siemens Output Module is a vital part of the SIMATIC PLC system, acting as the translator between the Central Processing Unit’s (CPU) calculated control commands and the actual physical control of field devices (actuators). It converts digital or analog signals from the PLC program into the corresponding electrical energy to drive machinery.

Siemens Output Modules are divided into two main categories based on the signal they deliver:

• Digital Output (DO) Modules:
  • Used for controlling binary (ON/OFF) actuators such as relays, contactors, solenoid valves, and indicator lights.
  • They vary by the switching element:
    • Transistor (Solid-State) Outputs: Used for DC loads (typically $24 text{V DC}$), offering high switching frequency and longer life due to no mechanical wear. They are categorized as Sourcing (PNP) or Sinking (NPN).
    • Relay Outputs: Used for both AC and DC loads with higher current ratings, providing galvanic isolation and flexibility for different voltages. They have lower switching frequency and finite contact life.
• Analog Output (AO) Modules:
  • Used for controlling proportional actuators that require a variable signal, such as variable frequency drives (VFDs), control valves, and proportional solenoids.
  • They accept a digital data word from the CPU and use a Digital-to-Analog Converter (DAC) to generate a proportional industrial signal (e.g., $0-10 text{V}$ or $4-20 text{mA}$).

These modules are highly modular, designed for either centralized mounting (next to the CPU) or distributed I/O systems.

Product Parameters

Product Advantages

• Advanced Diagnostics and Safety: High-feature modules offer channel-specific diagnostics, including short-circuit, wire-break, and supply voltage monitoring, which significantly increases plant availability and speeds up fault finding.
• Configurable Substitute Values: Allows the user to pre-define a safe fallback value for the output channel in the event of a module or CPU failure (e.g., output forced to 0 or last value), ensuring safe machine shutdown or operation.
• High-Speed Control: Transistor output modules and specialized technology modules support extremely fast switching frequencies (e.g., Pulse Width Modulation (PWM) or Pulse Train Output (PTO)), essential for precision motion control.
• Failsafe (F) Options: Dedicated Failsafe Digital Output modules integrate safety functions, allowing actuators in safety-critical applications to be controlled and monitored from the same platform (certified up to SIL 3/PL e).
• Extended Life Features: Relay modules often include a switching cycle counter feature, allowing preventative maintenance to be scheduled before the physical relay contacts reach their specified end of life.

Important Notes

• Load Type and Current: Never exceed the maximum permissible current per channel or the total current per group/module. Exceeding ratings will lead to thermal shutdown or permanent damage.
• Output Isolation: Always consider the required isolation. Relay outputs provide good galvanic isolation, while solid-state outputs typically offer less or none, which affects their suitability for controlling high AC voltages.
• Inductive Loads: When switching inductive loads (contactors, solenoids), ensure external protective elements (snubber circuits, diodes) are used if not integrated into the module, to prevent high voltage spikes from damaging the switching elements.
• Analog Scaling and Actuator Response: For AO modules, the digital output value must be carefully scaled in the PLC program to match the physical response range of the controlled actuator (e.g., $0 text{V}$ to $10 text{V}$ corresponds to $0%$ to $100%$ valve opening).

Product Applications

• Discrete Manufacturing (Factory Automation): Driving solenoid valves for pneumatic or hydraulic control, switching motor starter contactors, and controlling indicator lights/stack lights.
• Motion Control: Generating high-frequency Pulse Train Outputs (PTO) for precise speed and position control of stepper or servo drives.
• Process Control: Providing variable control signals (e.g., $4-20 text{mA}$) to control valve positioners, speed references for variable frequency drives (VFDs), and dosing pumps.
• Robotics and Packaging: Fast switching outputs for rapid ejection or clamping actions where quick response time and high cycle life are critical.
