The Power Mate has eight highspeed DI signal interface points. They
are accommodated in the CB156 connector, which is also used for the
builtin DI/DO signals. See Section 6.4.1 for the connector specification,
pin assignment, and the cable between the connector and connector panel.
The highspeed DI signal interface shares input pins with the X1003
signals for the builtin DI points. Whether the highspeed DI signal
interface or the builtin DI points use the input pins is specified using a
parameter. So, when the highspeed DI signal interface uses the input
pins, the X1003 signals for the builtin DI points cannot use them.
The highspeed DI signals shall be free of chattering. The following are
requirements for the contacts for the signals on the machine side. (24
VDC system)
Contact capacity:
30 VDC, 16 mA or greater
Opencircuit contacttocontact leakage:
1 mA or less (for 26.4 V)
Closedcircuit contacttocontact voltage drop:
3.5 V or less (for 8.5 mA, including a voltage drop across the
cable)
