22ZC Zone Controller
Nearly all accumulation conveyor control systems require
a sensor, actuating device, and zone control logic.
This
is typically achieved through the use of mechanical
switches and pneumatic valves connected to a PLC programmed
with zone control logic. The Bulletin 22ZC zone controller
is a revolutionary new alternative that is compatible
with a wide variety of sensors—mechanical to
photoelectric—as well as with either pneumatic
or powered roller actuators.
The 22ZC zone controller does not require the complex
programming tools used by an embedded I/O or PLC system.
Selection of either powered roller or pneumatic conveyor
systems along with other advanced logic functions can
be made with a single DIP switch.
The heart of the 22ZC system is the zone control module.
One module is mounted in every zone of the conveyor
system and connected to the modules in other zones
via a flat cable. This allows peer to peer communication
between zones, enabling smooth handling of material
along the entire conveyor. Each module accepts a
sensor input and provides an output to an actuator
(pneumatic
valve or powered roller driver card) based on the
desired zone control logic for the application. This
logic
includes both standard and advanced zone control
functions, which can be configured by the user without
the need
for any programming tools. Functions include:
- Singulation and slug release modes
- Selectable
sleep and jam detect functions, ON and OFF time
delays
- Selectable inverted output (N.O. or N.C.
output)
