Since some power supplies can be omitted, modifications are required to avoid a false under-voltage detection. Such modifications are reported when the +24V source is not connected.
The SMB-Series modules are designed to operate from several DC power supplies. Each module has two 50-pin stack-through headers acting as a power bus when several boards are stacked. While the SMB00 module is recommended to connect the supply sources to the bus, the alternative way to power the stack is described.
Since this module is fully compatible with the SMB00 module, please visit the relevant product page.
