Digital I/O expansion boards increase the number of I/O points. These boards connect to the controller via a plug-in cable. Several expansion boards can be daisy chained, up to a maximum of 32 outputs and 32 inputs (or 32 bidirectional I/O points). When you connect expansion boards the controller detects them automatically and the programming software adjusts itself. There is no software configuration required.

XBIO16

This board gives you 16 bidirectional I/O points that can each be used as in input or an output.

MBIO16 NEW!

Similar to XBIO, but with outputs rated at up to 2A. 16 bidirectional I/O points that can each be used as in input or an output.

FP16

Add 8 inputs and 8 outputs. Inputs are NPN/PNP selectable. Outputs sink up to 400mA.

XIRO16

8 5A/240V relays and 8 digital inputs, this is the ideal expansion board where medium duty relay outputs are required.

HIO16

Eight relays each rated 20A at 240V with an 80A inrush rating. Alternatively they are UL rated for 1HP. The board also has eight opto-isolated inputs capable of working at 24V through 240V AC or DC.
