Spare-part CPU for existing S7-200 CN lines
The 6ES7214-1BD23-0XB8: With 14 digital inputs and 10 relay outputs, this compact device handles mixed discrete control for conveyors, packaging machines, or simple process skids where the I/O count fits within the onboard terminals.
I/O and memory fit for the BOM line
The 14 DC digital inputs and 10 relay outputs (the latter rated for general-purpose AC/DC loads up to 2 A per channel typically) cover a 24-point I/O budget without an expansion module. Program memory is 8 KB or 12 KB depending on the firmware version; data memory is 8 KB. Typical power loss is 10 W, which sets the thermal load inside the enclosure — a panel with several such CPUs should account for this in the cooling calculation. Dimensions are 120.5 mm wide, 80 mm tall, and 62 mm deep — the width determines the DIN-rail footprint and spacing in a crowded cabinet.
