8.12 Dual action heating-cooling ATR142 is suitable also for systems requiring a combined heating-cooling action. Main command output must be configured foe hearting PID ( act.t. = Heat and p.b. must be greater than 0), and one of the alarms ( AL. 1 or AL. 2 ) must be configured as cooL. Command output must be connected to the actuator responsible for heat, while the alarm output will control cooling action.

Технический паспорт Pixus ATR142 Универсальный контроллер с дисплеем и интерфейсом RS-485 (752 КВ)
Автоматический регулятор температуры
Модель: ATR142
Производитель: Pixsys
Автоматический регулятор температуры, трехпозиционный, размеры — 32х74мм. Двойной красно-зеленый экран одновременно отображает текущие и заданные значения. Импульсный источник питания с расширенным диапазоном потребляемого тока 24…230В переменного/постоянного тока, позволяет обойтись без настройки переключателей.
Аналоговый вход автоматического регулятора температуры по выбору для термопар типов J, K, S, R, терморезисторов PT100, PTC 1К, NI100, NTC 10K (холодильная промышленность) и PT500/PT1000 (широко используется при кондиционировании воздуха), 0…1В, 0…10В, 0…20мA, 4…20мA. Возможно считывание показаний с потенциометров со шкалой до 6KΩ и 150KΩ, и использование функции «Latch on» (Захват) для быстрой калибровки и установки минимального, максимального и нулевого значений с помощью кнопок на передней панели (см. Заметки по применению).
Автоматический регулятор температуры имеет возможность установки трех контрольных значений, для функций управления и сигнализации. Они могут быть соотнесены с двумя релейными выходами или с выходом SSR. Основное реле контрольного выхода 8А. Реле сигнализации 5А (режимы срабатывания сигнализации: порог, полоса, отклонение; возможность ручного сброса выходного сигнала с помощью клавиатуры на лицевой панели для Ограничения работы автоматического регулятора температуры; функция включения с задержкой). Алгоритм Открыть/Закрыть для управления электроприводными клапанами.
Программные функции автоматического регулятора температуры: Вкл/Выкл, PID+ автоматическая настройка и PID Тепло-Холод с нейтральной зоной. Доступна модель с одним выходом (1 реле + SSR), с последовательным интерфейсом RS485 и Modbus-RTU / Slave протоколом для использования в системах диспетчерского управления.
Крышка для лицевой панели автоматического регулятора температуры(дополнительная опция) соответствует классу защиты IP65.
Как опция доступна карта памяти для сохранения параметров, может комплектоваться батарейкой, что позволяет не включать питание прибора.
Программное обеспечение LabSoftView для Windows позволяет установку и контроль параметров через ПК.
Отдельно можно заказать специальную версию программного обеспечения, которая объединяет в приборе простую систему автоматического управления и функцию Таймера (с прямым/обратным отсчетом времени для и/или Паузы/Работы).
Продукт сертифицирован согласно ГОСТ. Номер сертификата 0332323 от 14.07.2010.
Thank you for choosing a Pixsys controller.
With the ATR142 model Pixsys makes available in a single device all
the resources relevant to sensor input and actuators command, in
addition to the extended power range 24…230 Vac/Vdc. With 17
sensors to select and outputs configurable as relay or SSR command,
the user or retailer can reduce warehouse stock by rationalising
investment and device availability. The series is completed with
models equipped with serial communication RS485 Modbus. The
configuration is further simplified by the Memory cards which are
equipped with internal battery and therefore don’t require cabling to
power the controller.
The range of ATR142 controllers comes in two versions. Refer to the
table below to easily select your preferred model.
