ALTOFLUX IFM x080 K-EEx and ALTOFLUX IFM x080 K / i-EEx 13

2.4 Regular IFC 090-EEx electronics unit

The field cables that enter the terminal compartment of the IFC 090-EEx signal converter unit (i.e.

power supply, current and binary outputs) are non-intrinsically safe. To connect external devices to the

signal output terminals, the wiring requirements for the type of protection of the compartment (standard:

increased safety "e", optional: flameproof "d") must be conform to the international or national standard

involved (e.g. EN 60079-14).

The terminal arrangement is shown below.

Note:

The binary outputs (terminals B1, B⊥ and B2) can only be configured as passive outputs,

the current output (terminals I+ and I) can only be configured as active output.
