The VCCX2 Controller is designed with 8 analog inputs, 4 analog outputs, 8 binary inputs, and 8 relay outputs. It also has an on-board BACnet port for connection to MS/TP network. The Controller contains a 2 x 8 LCD character display and 4 buttons that allow for status and alarm display and force modes as well as BACnet configuration.

The VCCX2 Controller provides for Constant Volume, VAV, Single Zone VAV, MUA, and Air to Air Heat Pump applications. Most common HVAC unit controls applications can be configured using only the VCCX2 Controller. If the application requires more inputs and /or outputs, the VCC-X EM1 Expansion Module, the Refrigeration System Modules, and the E-BUS 12 Relay Expansion Module are available to provide for additional analog, binary, or digital inputs, outputs as required.

The VCB-X Controller is designed with 5 analog inputs, 3 analog outputs, 1 triac output, 4 binary inputs, and 6 relay outputs. It also has an on-board BACnet port for connection to MS/TP network. The Controller contains a 2 x 8 LCD character display and 4 buttons that allow for status and alarm display and force modes as well as BACnet configuration.

If the application requires more inputs and /or outputs, the VCB-X EM 1 Expansion Module, the VCB-X EM2 Expansion Module and the VCB-X 12 Relay E-BUS Expansion Module are available to provide for additional analog, binary, or digital inputs, outputs as required.

The VCM-X E-BUS series of controllers consists of the VCM-X Modular E-BUS and the VCM-X WSHP (Water Source Heat Pump) E-BUS Controller. The E-BUS versions of these controllers now allow the various E-BUS modules to connect directly to the VCM-X E-BUS Controllers.

These controllers are designed with 7 analog inputs, 2 analog outputs, and 5 relay outputs. Each input and output can be expanded with the VCM-X Expansion Module, the 12 Relay Expansion Module, and the 4 Binary Input Expansion Module by means of a modular cable. Each VCM-X E-BUS Controller can be configured for control of VAV Units, Constant Volume Units, and Make-Up Air Units.

The RNE Modular Controller is designed with 7 analog inputs, 2 analog outputs, and 5 relay outputs. Each RNE Controller’s input and output capabilities can be expanded with the VCM-X Expansion Module, the 12 Relay Expansion Module and the 4 Binary Input Expansion Module by means of a modular cable.

The RNE Controller also allows various E-BUS modules to connect directly to it. There would include the Full Digital Module, the Two Condenser Head Pressure Module, and the Water Source Heat Pump Modules.

Each RNE Controller can be configured for control of VAV Units, Constant Volume Units, and Make Up Air Units.

The SA E-BUS Controller is designed with 6 analog inputs, 2 analog outputs, and 5 relay outputs. Most common HVAC unit control applications can be configured using only the SA E-BUS Controller; however, if needed, the SA E-BUS Controller’s input and output capabilities can be expanded with the SA Expansion Module or 12 Relay Expansion Module by means of a modular cable.
