Управление нагревом Siemens (Сименс) доставка по России со склада и под заказ

Nowadays, the HS 724i heater control can be used to control heat emitter arrays and other resistive loads in industrial applications. The connection is made using PROFIBUS DP, and provides - e.g. together with the SIMATIC S7 - a highly modern and powerful automation system. An NE 724 line voltage detector can be integrated as an option in order to internally compensate variations in the line voltage automatically.

Область применения

Дизайн

The main components of the HS 724i heater control are:

ZA 724 central interface module
NE 724 line voltage detector module (option)
LA 724i /LA 724iHP/LA 724iSSR power outputs
Up to 16 power outputs can be connected via the ZA 724 central interface module
LM 724 fan module (option)
SM 724i current measuring module (option)
Communication via PROFIBUS DP
e.g. with SIMOTION, SIMATIC S7, or industrial PC

The ZA 724 central interface module and the LA 724i/LA 724iHP/LA 724iSSR power outputs are each fitted in a metal encapsulation and mounted on a plate in the control cabinet. Customized, distributed solutions are also possible.
