VCTB-4000
Four Zone, 24 Volt DC
Valve Gate Controller
GENERAL DESCRIPTION
This manual describes the installation,
operation and servicing of the Valve Gate
Controller.
The VCTB-4000 Valve Gate Controller is
designed to provide time based control of
up to four 24 volt DC valves used to actuate
pneumatic valve gate cylinders. It can also
be used to operate some hydraulic valves.
The VCTB-4000 is small in size so that it is
extremely portable and requires minimal
counter space.
The Controller uses DIN style solid state
timers to provide long life and high
reliability. Each timer is capable of dual time
functions so that each zone can be
programmed with a delay time (timer 1) and
an on time (timer 2). The timers in turn drive
larger solid state relays that are individually
fused against faults.
The Controller is designed to operate from a
wide supply of operating voltages (88 to 264
Volts AC) so that this one device can be
used with almost any available power
source. This also makes it easier to relocate
the controller between different plants or
even different countries. The standard
product offering comes with a 125 volt AC
plug (North American Standard). This plug
may be removed and replaced with any
number of 240 VAC plugs. Units may also
be custom ordered with other plugs, as
required.
A single DB-025 cable connects the
controller to up to four remotely located
valves minimizing required wiring and air
connections, thereby making the molding
environment neater.
DME offers valve and manifold systems that
accept the DB-025 cable directly. For other
systems that have independent valve
connections, breakout boxes are available
that accept the DB-025 connector and
provide a terminal strip for individual valve
connections.
