• 4, 8 and 16-channel digital output (DQ) modules
• Apart from the standard delivery form in an individual package, selected I/O modules and BaseUnits are also available in a pack of 10 units. The pack of 10 units enables the amount of waste to be reduced considerably, as well as saving the time of unpacking individual modules.

For different requirements, the digital output modules offer:

• Function classes Basic, Standard, High Feature and High-Speed as well as fail-safe DQ (see "Fail-safe I/O modules")
• BaseUnits for single or multiple-conductor connection with automatic slot coding
• Individual system-integrated load group formation with self-assembling voltage distribution bars (a separate power module is no longer required for ET 200SP)
• Option of connecting actuators with rated load voltages of up to 120 V DC or 230 V AC and load currents of up to 5 A (depending on module)
• Relay modules
  • NO contact or changeover contact
  • for load or signal voltages (coupling relay)
  • with manual operation (as simulation module for inputs and outputs, jog mode for commissioning or emergency operation on failure of controller)
• PNP (source output) and NPN (sink output) versions
• Clear labeling on front of module
• LEDs for diagnostics, status, power supply and faults
• Electronically readable and non-volatile writable rating plate (I&M data 0 to 3)
• Extended functions and additional operating modes in some cases
  • MSO operating mode (simultaneous reading of input data from as many as three other controllers)
  • Pulse width modulation mode (output value as pulse-pause ratio of between 0.0% and 100.0% for controlling the output current)
  • Oversampling (n-fold equidistant output of digital values within a PN cycle for the precise time control of an output or a sequence of output values)
  • Isochronous mode (simultaneous equidistant output of all output channels)
  • Output of substitute value in the event of interruptions to communication (0, 1 or last value retained)
  • Re-parameterization during operation
  • Firmware update
  • Valve control (output signal does not switch automatically after a set pickup time to a current-saving PWM output)
  • Diagnosis of wire break and short-circuit (on channel or module basis)
  • Value status (optional binary validity information of the output signal in the process image)
  • Support of the PROFIenergy profile
• Optional accessories
  • Labeling strips (film or card)
  • Equipment labeling plate
  • Color-coded label with module-specific CC code
  • Shielding terminal

A quick and clear comparison of the functions of the different DQ modules is offered by the TIA Selection Tool.
