OE335-26B-
VCBX-A
VCB-X Controller
The VCB-X Controller provides 5 analog inputs, 3 analog outputs, 1 triac
input, 4 binary inputs, and 6 user-con
fi
gurable relays. It also has an on-
board BACnet port for connection to an MS/TP network. The Controller
contains a 2 x 8 LCD character display and 4 buttons that allow for status
and alarm display as well as BACnet con
fi
guration. It presently allows for
the addition of the EM1 Expansion Module and the 12 Relay Expansion
Module described below.
NOTE:
Set-up, con
fi
guration, and monitoring of the VCB-X Controller re-
quires one of the following communication interfaces—Prism 2 Front-End
Software used with a personal computer, System Manager Touch Screen,
or Modular Service Tool SD.

OE336-
23-EM1-A
VCB-X EM1 Expansion Module
The EM1 Expansion Module adds VAV applications, building pressure
control, head pressure control, water source heat pump monitoring, and
other functions. It provides 6 additional analog inputs, 3 binary inputs, 5
additional relays, and 4 analog outputs. It connects with an EBC E-BUS
cable to the VCB-X Controller.

OE336-
23-EM2-A
VCB-X EM2 Expansion Module
The EM2 Expansion Module adds remote forced heating, cooling, and
dehumidi
fi
cation using 3 additional binary inputs. It provides 2 analog
outputs for controlling a Return Air Bypass Damper and a Return Damper
in Return Air Bypass applications. It also has an analog input that can
be used as a remote voltage input to reset the Supply Air Setpoint or as
a Title 24 Economizer feedback signal. It connects with an EBC E-BUS
cable to the VCB-X Controller.

OE358-23E-
12R-A
VCB-X E-BUS 12 Relay Expansion Module
The VCB-X 12 Relay Expansion Module adds 12 con
fi
gurable relays to
the VCB-X Control System. It connects to the VCB-X Controller with an
EBC E-BUS cable.
