GRS COMMAND SIGNAL CONNECTION

The GRS-H series can be controlled by DC and AC logical signals managed through push-in connectors for a faster and easier connection, even without tools. The ON / OFF status of the static device is always displayed by a green LED on the front panel, for an immediate view of its operation.

DIAGNOSTICS AND ALARMS

The GRS-H series offers a series of diagnostic information associated with a physical alarm output with voltage-free or

PNP-type isolated contact. The thermal alarm is triggered if heat dissipation exceeds a critical threshold, signaling it with a yellow led on the front panel, interrupting the power supply, and triggering the alarm output (NO or NC). This function is available for all sizes as an option. The absence of current on the load (for models with DC control) is indicated by a red LED on the front panel and by the activation of the alarm.
