MicroNet 50 Series Controllers

MN550

Programmable controller

The MN550 controller is designed for district heating, boiler plant, air handling unit

(AHU), and zone heating and cooling applications.

The controller can function in stand-alone mode or as part of a networked system

using Bus-du-jour communication options. An optional Real Time Clock Card (RTC)

can be fitted to the MN550 on an NCP network. Other options include a remote

mounting Touch Screen Display which allows the user to view, query and edit

controller properties. An LCD display option is also available to review the

controller parameters locally.

INSTALLATION DETAILS

Power supply:

24Vac, 50/60Hz

Consumption:

12VA

Protection class:

IP 40

Mounting:

Wall or 35mm DIN rail

Inputs:

2 digital pulse counting (10Hz) inputs, 10 universal inputs (digital, resistive,

0 to 10Vdc)

Outputs:

6 digital outputs (Line Relay) 5A resistive at 230Vac. 4 analogue outputs

(0 to 10Vdc)

Power failure reserve:

Controller EEPROM preserves memory for 10 years under

normal conditions of use. The software clock will stop during a power failure.

If the controller has been fitted with an optional RTC card, time is maintained.
