Protection rating

"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.

IP67
Primary application

"Control cabinet":
Cost-optimized modules whereby the supply voltage for the sensors and actuators is connected via additional patch terminals. Optimal application in the main control cabinet.


"Decentralized control cabinet":
Ideal for use in decentralized control cabinets. 3-wire sensors or actuators can be connected directly to terminals in the module

without additional patch terminals or the module has an extremely flat design.

-
Flat design, installation in cable duct possible

Modules with a flat housing design and with cables which exit the sides make these ideal for installation in cable ducts, cable channels, cable troughs, cable rails or cable trays. Please note the respective housing depth for your particular installation.

Input voltage (sensor supply)

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

Output voltage (actuator supply)

Electronic outputs are supplied by ASi or by AUX (auxiliary 24 V 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.

Connection

PUR line, oil resistant. Further connection options are available on request.

      M12 socket M12 cable socket, angled  M12 cable socket, straight   M8 cable socket, straight   round cable/connecting wires     profile cable branch          push in terminals
       2 x round cables/connecting wires 2,5 mm²

4 x M12 sockets, 5 poles
Round cable

Under normal conditions (no bus termination or repeater), the permissible total length of the ASi segment is max. 100 m. The calculation should take into consideration that the length of the connection cable (round cable) for each connected passive distributor must be doubled.

In the case of the active distributors (ASi slaves) however only the one ASi profile cable is counted.

-
ASi connection

the connection to ASi as well to AUX (auxiliary 24 V power) is made via yellow resp. black ASi profile cable with piercing technology or via M12 socket (in IP20 via clamps).

ASi profile cable
ASi address

AB Slave (max. 62 AB Slaves/ASi network), 2 AB Slaves (max. 31 modules with 2 AB Slaves), Single Slaves (max. 31 Single Slaves/ASi network), ASi-5 Slave (max. 62 ASi-5 Slaves/ASi network), mixed use allowed.
For modules with two slaves the second slave is turned off as long as the first slave is addressed to address "0".
Upon request, slaves are available with specific ASi Slave profiles.
