- Provides the base for 24 VDC X20 I/O modules
- Passes the internal I/O power supply through the existing potential group
- Adds manual node-number assignment that can be combined with automatic addressing
X20BM15 is a B&R bus module with node number switch designed for the X20 System.
The module supports an X20 electronic module and terminal block, continues the existing 24 VDC I/O potential group, and permits a fixed station address independent of the installed electronic module.
Before installation or replacement, verify the complete material number, 24 VDC keying, node-number switch setting, electronic-module and terminal-block compatibility, potential-group continuity, 10 A contact-load limit, neighboring modules, and the documented station address plan.
Availability, condition, price, and shipping time for X20BM15 are confirmed during quotation.
