SCC2-P

Controller and Sensor (X2 OS) for Air Differential Pressure

The SCC2 is a programmable controller and sensor with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages. The SCC2 comes with a built in RS485 communication interface that allows peer to peer communication with an operation terminal such as OPT1-(2TH)-VC.

Communication plug-in allow for integration of the controller into a network. These modules are described in their own manual. Currently available are plug-ins for BACnet and MODBUS.

Flexible application configuration is made with a parameter-setting routine using the standard operation terminal.

Complete parameter sets may be copied by use of an accessory called AEC-PM2 or exchanged with a PC using an RS485-USB converter and the EasySet program.

Applications

Pressure measurement in the field of heating, ventilation and air conditioning
Measuring of air flow velocity
Measuring and control of positive or negative pressure for example for clean rooms
Supervision of critical pressures
