Power output modules Siemens

Обзор



The power output modules are an important component of the SIPLUS HCS716I heater control.

Three different power output modules can be used depending on the application:

  • LA716 power output module – the universal version
  • LA716I power output module – the innovative version
  • LA716I HP power output module – the HighPower version

Power output modules LA716 (left), LA716I (center) and LA716I HP (right)

LA716 power output module

The universal power output module provides 16 channels for connecting resistive loads. Up to 650 W can be used per output channel.

LA716I power output module

The innovative power output module provides 16 channels for connecting resistive loads. Up to 1 150 W can be used per output channel.

LA716I HP power output module

The HighPowerversion provides 8 channels for connecting resistive loads. Up to 2,300 W can be used per output channel.

Дизайн


  • Connection of the heat emitters by means of two 8-pin mating connectors (the heat emitter and mating connector must be ordered separately.)
  • Mains infeed at the front:
    • LA716 power output module: 3-pole terminal (Lx/N/Ly)
    • LA716I and LA716I HP power output modules: 3-pole connector (Lx/N/Ly)

Функции



Power switching elements

  • Power triacs with zero crossover switching
  • Protection of triacs and opto-triacs against overvoltages by Transil diodes

Output power

LA716 power output module

  • 16 power channels of 230 V each (8 outputs per phase)
  • Max. 10 400 W switching capacity per module

LA716I power output module

  • 16 power channels of 230 V each (8 outputs per phase)
  • Max. 14 720 W switching capacity per module

LA716I HP power output module

  • 8 power channels of 230 V each (4 outputs per phase)
  • Max. 14 720 W switching capacity per module

Temperature monitoring

There is an NTC thermistor on the heat sink for monitoring its temperature. In the event of an overtemperature, this temperature-dependent resistor issues a signal to the higher-level controller.

Fuses

LA716 power output module

  • Each output is protected by a 5 A fuse in an accessible fuse holder for protection of the power triac.
  • A fuse cover is provided as a shock hazard protection.

LA716I power output module

  • Each output is protected by a 5 A fuse in an accessible fuse holder for protection of the power triac.
  • A plexiglass cover is provided as a shock hazard protection on the front.

LA716I HP power output module

  • Each output is protected by a 10 A fuse in an accessible fuse holder for protection of the power triac.
  • A plexiglass cover is provided as a shock hazard protection on the front.

Diagnostics facilities

Diagnostics functions are provided as standard to detect the following faults:

  • Circuit breaker triac at high resistance or internal fuse blown
  • Channel fuse blown on the module
  • External fault such as blown fuse, heat emitter or cable breakage
