Description

ECL Apex 20

ECA 20 (ECL Apex Web Panel)

The ECL Apex 20 and the ECA 20 (ECL Apex Web Panel) are used in large district heating applications. The products are designed and produced by the company Saia-Burgess.

The ECL Apex 20 is a free programmable controller (FPC / PLC) for temperature and pressure control as well as monitoring of district heating systems.

The ECL Apex 20 is operated by means of either a PC or the ECL Apex Web Panel.

Temperature input signals are based on Pt 1000 or 0 - 10 V.

Pressure input signals are based on 0 - 10 V.Activation of the motorized control valves is based on 0 - 10 V signals. Activation of the pumps is based on relay outputs.

The advantages of the ECL Apex 20 are among others:• Freeprogrammablecontroller• Flexibleinputandoutputconfigurationand

extension• Flexiblecommunicationpossibilities• Onboardwebserver• Webpanel,withtouchscreenincolours,

serves as display and is separated from the controller.

The ECL Apex 20 is to be placed inside a panel.
