AS-interface modules with encapsulated PUR housing, high signal density

Two new actuator/sensor interface modules from Belden are highly resistant to cooling lubricants and feature high signal density. Both are slave modules suitable for use in temperature ranges from -25 °C to +80 °C.


BeldenTwo new Belden actuator/sensor interface (AS-Interface) modules have encapsulated PUR housing (highly resistant to cooling lubricants) and high signal density.

The two new modules feature either an integrated T-piece functionality or piercing contacts. Both versions are slave modules with four digital inputs for two- or three-wire sensors and four digital outputs for standard actuators. Two inputs and two outputs are Y-connected and both modules support the latest AS-Interface profile in accordance with AS-Interface specification V3.0, providing the connection of up to 1,000 digital inputs/outputs. Compared to previous versions, the signal density has reportedly doubled. Each module contains eight M12 sockets for digital inputs and outputs. The assignment of Slave addresses is accomplished via the modules’ M12 bus connection by using an addressing unit and a connection cable.

Robert Strehmann, product manager says, “The modules’ high signal density will save users a significant amount of money because, depending on the network topology, they will require fewer modules overall.” Both versions (0910 ASL 146 and 0910 ASL 438) comply with the IEC 61076-2-101 and IEC 61131 standards, are IP 67 rated, and are suitable for use in temperature ranges from -25°C to +80°C. The power supply is designed for 11 to 30 V and the modules can be securely fastened with three screws. The dimensions of each module are 152 x 60 x 35.8 mm (length x width x depth).
