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 ASi modul for your requirements. Many of our modules also include available outputs for standard signals.

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).

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.

ASi connection

AB address (max. 62 AB addresses/ASi network), 2 AB addresses (max. 31 modules with 2 AB addresses), Single addresses (max. 31 Single addresses/ASi network), ASi-5 address (max. 62 ASi-5 addresses/ASi network), mixed use allowed.
For ASi modules with two ASi nodes the second Asi node is turned off as long as the first Asi node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.

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 modules) 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.

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.
