The ZA 724 central interface module is the intelligent processor module of the HS 724i heater control.

Особенности

• Connection facility for max. sixteen LA 724i/LA 724i HP/LA 724i SSR power output modules per ZA 724 central interface module
• Communication via PROFIBUS DP interface

Дизайн

• Module encapsulated in metal enclosure
• Two LEDs for normal operation (green) and fault (red)
• PROFIBUS DP interface (up to 12 Mbit/s)
• Rotary switch for setting the PROFIBUS DP address
• RS 232 C serial interface
• Parallel bus interface to the power outputs
• Expansion slot for NE 724 power supply measuring module (option)

Функции

Communication

PROFIBUS DP

• Importing of parameter settings from host controller
• Transfer of diagnostics information to host controller

Parallel bus (internal)

• Control and monitoring of max. 384 power channels

Performance features

• Calculation of heat emitter values of power output channels
• Setpoints adjustable from 0% to 100% in steps of 0.5%
• Uniform distribution of load over all channels and all HS 724i heat controls used in the group
• Simple adaptation to the respective production process by selection of up to 4 operating modes
• Mixed operation of the various power outputs is possible

Diagnostics

• Evaluation of diagnostics information from connected power output modules
• Phase-sequence detection indicating whether phases L1, L2 and L3 are correctly connected
• Automatic detection of mains frequency

Mains synchronization

To ensure synchronization between the power outputs and the connected power supply, phase L1 is used for synchronization. The respective switch-on times for phases L2 and L3 are subsequently calculated automatically.
