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

Features

  • Pressure measurement from ± 25 Pa up to ± 500 Pa (± 0.1 to ± 2 in H2O)
  • Two universally configurable control loops:
    • Functions for dehumidifying, set point shift and cascade control
    • Multiple auxiliary functions: heat-cool auto changeover, automatic enable, set point compensation
    • Free heating and cooling with economizer function based on enthalpy or temperature
    • Differential, averaging, min and max functions, enthalpy and dew point calculations
    • Transmitter function for inputs and set points
  • Universal analog outputs (VDC, mA)
  • Relay output with a normally open and a normally closed contact (SPDT)
  • Passive input for temperature NTC or open contact
  • 8 freely assigned alarm conditions, selectable state of outputs on alarm condition
  • Password protected programmable user and control parameters
