Power Output Module (POM) Siemens

Обзор



The power output modules (POMs) are an essential component of the SIPLUS HCS4200 heating control system.
Up to 12 power output modules can be operated on one CIM.

POM4220 low-end power output module:

  • 16 outputs for switching ohmic loads.
  • A current of up to 6.3 A can be used per output channel.
  • Module simply slides into the rack.
  • And is secured by one screw at the bottom and another screw at the top.

Дизайн


  • The heat emitters are connected via two 8-pole connectors (mating connectors are included in the scope of delivery)
  • Line feed (Lx/N/Ly) at the front by means of 3-pole connector (mating connector is included in the scope of delivery)
  • 1 fuse per output for the heat emitter supply circuit, in open fuse holders
  • Internal serial interface on the rear
  • 3 diagnostic LEDs for indicating module faults
  • 16 diagnostic LEDs for indicating channel faults

Функции



Power switching elements

  • Power triacs
  • Protection of triacs and opto-triacs against overvoltages by Transil diodes
  • Transfer of the diagnostics information to the central interface module (CIM)

Control modes

  • Half-wave control:
    Here the channel is controlled depending on the parameterized manipulated variable for each zero point. The controller outputs are set in values from 0 to 100 %.

Output power

  • 16 power channels of 230 V each (8 outputs per phase)
  • Switching power per output: Max. 1449 W at 230 V
  • Switching capacity per power output module: Max. 16100 W at 230 V

Ventilation

  • A fan module can be optionally mounted at the top of the rack so that 4 POMs can be ventilated and controlled dependent on the internal temperature.

Temperature monitoring

  • An NTC thermistor is installed in the device to monitor the internal temperature. An alarm threshold is defined for the internal temperature. The following reactions are triggered when the threshold is overshot:
  • Signal to the higher-level controller.
  • The channels are deactivated - regardless of which channel response was configured for error situations.

Diagnostic options

Implicit diagnostics functions are provided as standard to detect the following faults (diagnostics cycle does not affect the heating power):

  • Leading fuse defective / triac at high resistance (exception: setpoint 0%)
  • Triac failure (exception: setpoint 100%)
  • Heating element cable is defective (short-circuit and interruption)
  • Load defective (short-circuit and interruption)
