VAV Controllers & IOBus Slave Devices

 |
IOB-B1 and IOB-B2
The IOB-B1 and IOB-B2 series of products are I/O Bus devices that
provide expansion to the Walker line of controllers (WS1616s,
MiniSACs and MicroSACs). The modules come in many factory assembled
configurations and include a Belimo Motor with various
options of inputs and outputs.
IOB-VAV
The IOB-VAV I/O Bus Module provides a SAC with a unitary VAV
controller. The module comes in many factory-assembled configurations
for use as a complete unitary airflow station. The module can
include remote flow sensor and its input circuitry, motor and its
output drive circuitry, and additional inputs and outputs. The flow
sensor module is manufactured by Kavlico.

| Easy-VAV
Easy-VAV is a high power VAV controller that can operate
stand alone or under supervisory control. The Easy-VAV
communicates directly with the Gruner 227V VAV compact
actuator via PP Bus. Easy-VAV features highly fl exible
supervisory control or local access to all points, including
direct manual control of outputs.
The Gruner 227V VAV compact actuator contains a dynamic
differential pressure sensor. The volume flow is measured
according to the defi ned fl ow direction. An integrated
microprocessor controls measurement and control of the
actuator and communication.
The 227V VAV can be used for pressure independent
control of VAV boxes. Simple realisation of different
operating modes can be utilised by using override control
signals.

IOBus Expanders
The IOBus provides serial expansion to MiniSAC, MicroSAC2x, and MicroSAC3x products via a 2 wire cable. Expansion modules can be located up to 1000 feet from the controller and come with a range of digital and analog outputs and inputs.
