Frequently Asked Questions
What is the primary function of the GRI8-05 current monitoring relay?

It serves for monitoring heating systems in rail-switches, heating cables, consumption of single-phase motors, and indicates current flow status.

How do I adjust the measurement current range on the relay?

The measurement current range (2A-20A) can be flexibly adjusted using the built-in potentiometer on the front interface.

Does this current monitoring relay require disconnection of the current circuit for installation?

No, it utilizes a through-center design. This through-center installation is highly convenient and does not require you to disconnect the current circuit.

What are the input voltage and frequency specifications?

It features a universal voltage range of AC/DC 24V-240V, compatible with a rated supply frequency of 50/60Hz.

How is the operational status of the relay displayed?

The status is indicated by built-in LEDs. A green LED indicates the supply power status, and a red LED indicates the output relay status.

What type of mounting does this relay support?

It is designed as a standard 1-MODULE device and supports quick and secure DIN rail mounting (EN/IEC 60715).
