Product overview: Safety I/O Modules

Bihl+Wiedemann offers the right module for accessing any safety input signal. Both control cabinet modules (IP20) and field modules (IP67) are available. From a single safety input or output to safety multi-I/O modules we offer the right AS-i slave for your requirements. Many of our modules also include available outputs for standard signals.

Under normal conditions (no bus termination or repeater), the permissible total length of the AS-i 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 (AS-i slaves) however only the one AS-i 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.

Figure

Type

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

Input voltage (sensor supply)

Electronic outputs are supplied by AS-i or by AUX (auxiliary 24 V power). If supplied by AS-i, outputs shall not be connected to earth or to external potential.

For relay outputs the relay contacts are initiated from AS-i. The load circuit is powered externally as specified in the data sheet.

Output voltage (actuator supply)

PCB connection

status of in- and outputs is indicated by LEDs. In addition to that, both AS-i LEDs (PWR green and FAULT red) show as usual regarding the AS-i Slaves- the status of the AS-i Slaves. Uaux is indicated by a green LED.

LED status display

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

AS-i connection

AB Slave (max. 62 AB Slaves/AS-i network), 2 AB Slaves (max. 31 modules with 2 AB Slaves), Single Slaves (max. 31 Single Slaves/AS-i 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 AS-i Slave profiles.
