"IP20":
Protected against solid foreign bodies having a diameter of 12.5 mm or larger and against finger contact, not protected against water.

"IP40":

Protected against solid foreign bodies having a diameter of 1.0 mm or larger, protected against access with a wire, no protection against water.

"IP54":

Protection against dust in damaging amounts, complete protection against contact, protection against splashing water in any angle.

"IP65":
Dust-tight, full protection against contact, protection against spray water (jet) from any angle.

"IP67":

Dust-tight, full protection against contact, protection against temporary immersion.

Single wiring: 1 input or output per connection.

Y wiring: 2 inputs or outputs per connection.

Mixed wiring: 1 input and 1 output per connection.

Exact pin assignment see data sheet.
 

inputs are supplied by ASi or by AUX (24 V or 48 V auxiliary power). If supplied by ASi, inputs shall not be connected to earth or to external potential.

Electronic outputs are supplied by ASi or by AUX (24 V or 48 V auxiliary power). If supplied by ASi, outputs shall not be connected to earth or to external potential.

For relay outputs the relay contacts are initiated from ASi. The load circuit is powered externally as specified in the data sheet.

The connection to ASi and AUX (24 V auxiliary power) is made for modules in the active distributor or blue IP67 housing via the yellow or black ASi profile cable with piercing technology or via an M12 plug. Modules for the control cabinet are connected via terminals and PCB modules via wiring pins, connection wires or terminals.

Line protection: If the module is supplied via a M12 connection with A or B coding, it may only be used with a current load of max. 4 A per pin in acc. with IEC 61076-2-101 and IEC 61076-2-109. A fused tap is recommended. There is no such limitation for modules supplied via piercing contacts.

Bihl+Wiedemann offers modules with AB address, single address or ASi-5 address. In some cases, ASi modules can occupy several (different) addresses. Mixed operation of modules with different addressing in the same ASi circuit is permitted.
For ASi modules with two ASi-3 nodes, the second ASi-3 node is turned off as long as the first ASi-3 node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.
