Page 3: Function Description
Function description The PSS SB ACTIVE JUNCTION BASIS is a component part of the Pilz Active Junction. An Active Junction consists of a base unit (PSS SB ACTIVE JUNCTION BASIS) and up to two expansion modules (PSS SB ACTIVE JUNCTION EXPANSION). - Page 4 Terminating resistor in I/OD I/OD the main branch (terminator) IP20 main branch Terminating resistor for each sub branch of the Active Junction (integrated into the unit) PSS SB ACTIVE JUNCTION BASIS Field devices T-connectors sub branch (1) sub branch (2) Terminating resistor for the sub branch (terminator)

Page 5: Intended Use
Intended use The PSS SB ACTIVE JUNCTION BASIS is designed for use in SafetyBUS p networks. It is suitable for connecting physically remote field devices (e.g. light guards) to the SafetyBUS p main branch. Using the unit allows you to build a star or tree structure, rather than the linear topology specified for SafetyBUS p. -

Bus structure with PSS SB ACTIVE JUNCTION BASIS Rules for incorporation The Active Junction (base unit and expansion module) is transparent for all telegrams on the main branch and sub branches. If a signal error occurs within a sub branch (permanent dominant signal level), the sub branch will be ignored. Please note the following rules: •... -
Page 8: Determining The Bus Cable Runs And Transmission Rate
Determining the bus cable runs and transmission rate NOTICE Please read the information in chapter "Designing a SafetyBUS p network" of the "SafetyBUS p Installation Manual". If you are using Active Junction please also note: • Examine every connection combination between the first and last bus subscriber across all branches (see Fig. -

Page 10: Installation
Installation INFORMATION Please refer also to the chapter entitled “Installation and Assembly” in the “SafetyBUS p Installation Manual”. The PSS SB ACTIVE JUNCTION BASIS is enclosed in a 45 mm P99 housing, suitable for DIN rail mounting. • The device should be installed in a control cabinet with a protection type of at least IP54. -
Page 11: Supply Voltage
To achieve the lowest possible residual ripple, we recommend that you install a three-phase bridge rectifier or regulated supply. Insulation voltage test Pilz bus subscribers are connected to functional earth via protection elements on the voltage supply. Insulation voltage tests are only possible with voltages up to ca. 42 V. -
