Multi-channel power controller
A smart approach to fast, low-noise heater power regulation.
The G3ZA is a multi-channel power controller that provides clever
switching of up to eight solid state relays (SSRs). It is available
in four versions - either with 4 channels (with heater burnout
alarm) or 8 channels (without heater burnout alarm), and for
high- or low-voltage power supplies.
This multi-channel power controller is designed to improve
performance of existing heater switching control components
while reducing complexity and costs. Install the G3ZA beside
a bank of SSRs and reap the benefits of reduced wiring and
simplified programming control! The advantages of this
distributed control are immediately apparent. The small-sized
unit can control up to eight SSRs with only a single RS-485 2-wire
link to the PLC or PC. The manipulated variable control signal
(output %) from the PLC is automatically converted into a PWM
trigger signal within the G3ZA, so there is no need for an extra
conversion unit or digital output cards.
The G3ZA is designed according to Omron’s Smart Platform
concept for easy integration of components and systems.
PLC function blocks are available to significantly reduce ladder
programming time.
