ECL Apex 20 controller

Description

ECL Apex 20

ECL Apex 20 The ECL Apex 20 is used in large district heating

applications. The product is 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 a PC.

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

Application

Example 1:

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:

• Free programmable controller

• Flexible input and output conﬁguration and extension

• Flexible communication possibilities

• Onboard web server

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

All the mentioned components (SF = ﬂow meter, SP = pressure sensor, ST = temperature sensor, P = pump, M = motorized control valve) are wired to the ECL Apex 20.
