What is the purpose of the Relay interface?

The Relay interface provides robust alarming in industrial environments, supporting up to two fully isolated switches for reliable alarm responses.

How is the Relay interface installed on a CT device?

The Relay interface board is plugged into the designated slot beside the display and secured with M3x5 screws. Proper connection and configuration ensure reliable operation.

What is the capacity of the Relay switches?

The Relay interface supports switching up to 60 VDC/42 VACRMS at 0.4 A DC/AC.

How are alarm values set for the Relay interface?

Alarm values are set according to the device’s factory default settings and can be adjusted using the software via a digital interface like USB or RS232.

What visual indicators does the Relay interface provide?

The Relay interface includes a red LED indicating the switch is closed.

Can a digital interface and the relay outputs be configured simultaneously?

No, it is impossible to install a digital interface and the relay outputs simultaneously.
