BWU1955ASi-3 RS 232 Master in Stainless Steel, 1 master

Communication interface between fieldbus and gateway:

interfaces for standardized fieldbus systems in industrial automation. Bihl+Wiedemann offers a wide range of gateways for common fieldbus interfaces:

• PROFIBUS
• PROFINET
• EtherNet/IP^TM + Modbus TCP
• BACnet/IP
• DeviceNet
• ControlLogix
• Compact-/MicroLogix
• EtherCat
• POWERLINK
• CC-Link
• CANopen
• RS 485 Modbus
• OPC UA server

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

Standard 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.

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.

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.
