CT Built-in Solid State Relay G3PF
A new concept SSR solid state relay with built-in current transformer.
[Features]
· Can perform heater burnout and SSR short circuit failure detection.
· The built-in current transformer (CT) helps reduce the number of wiring steps.
· Detects the burnout of any one of a group of heaters.
· Detects the burnout of 3-phase heaters.
· Detects SSR short-circuit failures.
· The error detection level can be easily set by switch.
[Applications]
· The solid state relay can detect heater burnout, making it ideal for heater control.
