CPU I/O Connector
-
Requires Break-out terminal block model number XTB-40H.
-
Requires one of these Smart Link cables: C40HH-05SB-XBI, C40HH-10SB-XBI, C40HH-15SB-XBI, C40HH-20SB- XBI, or C40HH-30SB-XBI.
Note: The terminal block label that comes with XTB-40H does not match the PIN-out of the XEM CPU I/O Connector. AutomationDirect has provided a new label to print that will include the XEM CPU I/O Connector mapping with the XTB-40H pin out. You can download the label from the AutomationDirect website here.
