BL340 I/O Expansion
X board + up to 2 Y boards- One X slot plus up to two Y slots. X boards handle communication and digital I/O; Y boards handle I/O and measurement.
- Y63 (4×RS485/RS232) takes up the slot area by itself. If you fit this board, a second Y board will not fit.
- Boards are specified at the time of order, assembled and tested at the factory, and shipped fitted. They are not installed in the field.
