Bihl+Wiedemann: ASi-5 Safety I/O Module in IP20, 14SI/2SO (BWU4277)
BWU4277, the first freely configurable ASi-5 Safety Module in IP20 from Bihl+Wiedemann with up to 14 safe inputs and 2 safe outputs, can be used for almost all safety applications. When it comes to collecting safe and standard signals in the field, connecting safe high-end sensors, solving more complex safety applications, transmitting a variety of safe bits from different nodes, or utilizing diagnostics and additional information, ASi-5 Safety is the perfect complement to ASi Safety at Work.
The latest addition to the range of ASi-5 Safety modules from Bihl+Wiedemann has 14 inputs, which can be used as up to 14 one-channel safe inputs, as up to seven two-channel safe inputs (with adjustable test pulse width), or as up to 14 digital inputs. The safe inputs can thus be configured for almost any sensor – each as a standard or complementary switch, for OSSDs or floating contacts. An optional use of the two safe inputs SI13 and SI14 as EDM inputs as a feedback loop for contactor monitoring is also possible.
In addition to the (safe) inputs, the module also has two electronic safe outputs (two release circuits) with increased availability. The safe outputs (up to PLe) can also be configured as standard outputs if required. The ASi-5 Safety I/O module uses only one ASi-5 address and has extensive features which optimize the costs for safe inputs and outputs on ASi. With a width of only 22.5 mm, the module also offers significant savings potential in the control cabinet.
