Features

Multi-channel power controller for smarter SSR usage

The G3ZA receives manipulated variables generated by control loops or manual settings via a simple-to-wire RS-485. It regulates the heater power with high precision by driving up to eight standard SSRs. Moreover, the offset control reduces peak power in the supply net.

  • Multi-channel power controller
  • Controls up to eight standard solid state relays
  • Easy integration with PLC
  • Compact size
  • Available with heater alarms (four channels) or without (eight channels)

Optimum cycle control

Optimum cycle control is performed by driving SSRs according to load power detection and trigger signals. (Zero-cross SSRs are used.)

Noise is suppressed while ensure high-speed response by turning outputs ON and OFF each half cycle to achieve high-precision temperature control.
