Satchwell MicroNet
MicroNet 50 Series Controllers
MN450
Programmable Controller
The MN450 controller is designed for rooftop, unit vent, air handling unit (AHU), and
central 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 can be fitted to the MN450 on an NCP network.
INSTALLATION DETAILS
Power supply:
24Vac, 50/60Hz
Consumption:
10VA
Protection class:
IP 20
Mounting:
Wall or 35mm DIN rail
Inputs:
6 universal inputs (digital,
resistive, 0 to 10Vdc)
Outputs:
6 digital outputs (triac) for
switching 24Vac, 3 analogue outputs
(0 to 10Vdc), Current ratings for triacs:
18VA at 24Vac. Also has a 15Vdc power
supply output capable of sourcing 25mA
Power failure reserve:
Controller
EEPROM preserves memory for 10 years
under normal conditions of use. The
software clock will stop during a power
failure. However, if the controller has
been fitted with an optional RTC card,
time is maintained.

MN350
Programmable Controller
The MN350 controller is designed for unitary control, heating, cooling and special
applications that may require built-in transformers and relays. The controller can
function in stand-alone mode or as part of a networked system using Bus-du-jour
communication options.
