The SIPLUS HCS716I heater control system was developed as a cost-optimized controller of heat emitter arrays in thermoforming machines. It is suitable for all generally available radiation devices such as quartz, quartz material, ceramic, halogen and infrared radiation devices.

SIPLUS HCS716I can be used wherver low-cost, resistive loads of small to medium output require switching in an industrial environment.

The SIPLUS HCS716I family comprises four racks and three power output modules.

HCS716I heater controller

• High degree of modularity in terms of number of channels and channel performance

The SIPLUS HCS716I heater control system is used, for example, to switch the small and medium output heat emitter arrays in thermoforming machines, drying ovens and packaging machines.

The SIPLUS HCS716I is a distributed I/O unit (slave) that communicates over the PROFIBUS DP fieldbus with a higher-level control system (master) such as SIMATIC S7/SIMOTION.

The main components of the SIPLUS HCS716I heater control system are:

• 19" rack with bus board for inserting up to 4 or up to 12 power output modules, as well as a control module and CPU module
• Power output modules in double-height Eurocard format with 8/16 output channels
• Fan units with one or three fans (option)
• Communication over PROFIBUS DP, e.g. with SIMOTION, SIMATIC S7, or industrial PC
• Plug-in card system on the front

Example of application with SIMOTION, SINAMICS and HCS716I

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.

• 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)

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
