BWU2794ASi-3 PROFIsafe via PROFINET Gateway with integrated Safety Monitor, 1 ASi master

The device communicates via the standard ASi-3 and/or ASi-5.

The device communicates safely via the standard ASi-3 Safety and/or ASi-5 Safety.

Safe inputs can be configured as 1-channel or 2-channels depending on the desired application or PL and SIL level.

Suitable for applications up to category 4/PLe/SIL 3.

An externally connected relay (contactor) can be monitored by connecting the feedback loop to the EDM input.

Suitable for applications up to category 4/PLe/SIL 3.

Safety devices

"Single Master" :

1 ASi network, 1 ASi-5/ASi-3 Master.

1 ASi network, 1 ASi-3 Master.

"Double Master" :

2 ASi networks, 2 ASi-5/ASi-3 Masters.

2 ASi networks, 2 ASi-3 Masters.

"Optional ASi Safety coupling circuit" :
2 ASi networks, 1 ASi-3 Master.

" yes, max. 4 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.

" yes, max. 8 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.

"yes, optimized for 2 x NEC class 2 power supplies"

Data decoupling integrated in the gateway. Optimized for use with 2 x UL certified 30 V/3 A power supplies with power limitation <100 W (BW4223). In combination 2 separate NEC Class 2 compliant ASi circuits are created.

"no, max. 8 A/ASi network, redundant supply ":

1 ASi power supply per ASi network. Gateway is powered in normal operation from one of the two ASi power supplies.

Should one ASi power supply fail, switching to the other ASi power supply allows all the diagnostics functions to be maintained and the unaffected ASi network continues to operate.

" no, max. 8 A/ASi network ":

1 ASi power supply per ASi network.

Access to ASi master and safety monitor via own software from Bihl+Wiedemann using the diagnostic interface (e.g. USB, RJ45, RS232). For certain devices with Ethernet-based fieldbus (PROFINET, EtherNet/IP), there is also the option of diagnostics and configuration directly via the fieldbus interface.

The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device.

Detects whether the same address has been assigned to two ASi nodes. Frequent error when using a handheld addressing device.

Checks the ASi line for interference effects such as noise, external voltages, ...

Using a C-program offers the possibility to run mini-PLC functions with a gateway.

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.

"IP20":

"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":

"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.
