Description

The NR 5/Ex electrode relay EX JOLA is designed to transmit control commands. They shall be installed in a control cabinet or other suitable protective enclosure. The switches are suitable for use in clean environments.

Relay with electrodes for mounting or DIN rail mounting via 2 drill holes, with connection terminals on top of the housing and with 2 built-in LEDs for alarm status indication.

The unit is designed for installation or installation of the switch box in a suitable protective enclosure outside potentially explosive atmospheres and can therefore only be installed in these locations. It is only suitable for use in clean environments.

Electronic relay NR 5 / Ex I (M1) / II (1) GD [Ex ia Ma] I / [Ex ia Ga] IIC / [Ex ia Da] The IIIC is designed to transmit control commands from an intrinsically safe control circuit to a non-isolated safe active current circuit. It must be installed outside potentially explosive areas in accordance with the relevant standards and regulations.

Ex ia II. T6 G. approved conductive electrodes such as types EL….. Ex II 2 G or II 1 G Ex ia II. T6 G., can be used in a truly safe control current circuit. The various application possibilities and the special conditions for safe use are described in the relevant installation, operation and maintenance instructions (sent on request).

Electrode relay Ex NR 5 / Ex I (M1) / II (1) GD [Ex ia Ma] I / [Ex ia Ga] IIC / [Ex ia Da] IIIC, based on the quiescent current principle: in OK state, the output relay is energised.

Electrode relay NR 5 / Ex I (M1) / II (1) GD [Ex ia Ma] I / [Ex ia Ga] IIC / [Ex ia Da] IIIC version A, based on the operating current principle: in OK state, the output relay is not energised.
