Output power
- 8 power channels of 230 V each (4 outputs per phase)
- Max. 2 300 W switching capacity per output at 100% simultaneity
- Max. 14 666 W switching capacity per module
- Power triacs with zero crossover switching
- Protection of triacs and opto-triacs against overvoltages by Transil diodes
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
On the LA716l HP power output module an externally accessible 10 A fuse is provided for protection of the power triacs.
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
