Active Distributors ASi Safety

Active distributors AS-i Safety from Bihl+Wiedemann allow you to make any safety sensor, safety push-button or switch AS-Interface capable. Even modules without their own AS-i terminal can be easily integrated into an existing AS-i network using these active distributors AS-i Safety. Other features include individually configurable connection options using M8 or M12 connectors, flying leads or push-in terminals to conform to the customer’s application, as well as a compact form factor, making them ideal for use in cable ducts.

Inputs Safety, SIL 3, Cat. 4

An externally connected relay (contactor) can be connected via a feedback loop to the Safety Monitor for monitoring purposes.

Inputs digital, EDM
Outputs digital Safety signal inputs

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.

Input voltage (sensor 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.

Output voltage (actuator supply)

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

Connection

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.

Round cable

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.

Flat design, installation in cable duct possible
Profile cable 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 connection

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), 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.
