Description

GD Solid State Relays with Logic Control and Diagnostics

The GD series is a zero-crossing solid-state relay with integrated heater break diagnostics (HB function), selectable current range, and adjustable setpoint. Optional junction overheat protection is available.
An output alarm signal is provided for monitoring. GD relays are offered with 40A currents, 480Vac rated voltage, and Vdc input control signals. The voltage transistors are protected by built-in MOVs (varistors).
Refer to dissipation curves for additional performance data.
These relays require an appropriate heatsink and are designed for very short switching times, capable of millions of operations without component wear.
Optional accessories include heatsinks, fuses, and fuse holders.
