Overview

The IOM-1964 is an input/output module that connects to the DMC-17x8 motion controller and DB- 14064 extended I/O daughter board cards from Galil, providing optically isolated buffers for the extended inputs and outputs of the controller. The IOM-1964 also provides 16 high power outputs capable of 500mA of current per output point. The IOM-1964 splits the 64 I/O points into eight banks of eight I/O points each, corresponding to the eight banks of extended I/O on the controller. Each bank is individually configured as an input or output bank by inserting the appropriate integrated circuits and resistor packs. The hardware configuration of the IOM-1964 must match the software configuration of the controller card.

All DMC-1700 series controllers have general purpose I/O connections. On a DMC-1710/1810, - 1720/1820, -1730/1830, and -1740/1840 the standard uncommitted I/O consists of: eight optically isolated digital inputs, eight TTL digital outputs, and eight analog inputs.

The DMC-17x8 and DB-14064, however, have an additional 64 digital input/output points than the 16 described above for a total of 80 input/output points. The 64 I/O points are attached via two 50 pin ribbon cable header connectors. A CB-50-80 adapter card is used to connect the two 50 pin ribbon cables to an 80 pin high density connector. An 80 pin shielded cable connects from the 80 pin connector of the CB-50-80 board to the 80 pin high density connector J5 on the IOM-1964.

NOTE: Instead of the 80-pin connector at J5, on Rev. A of the IOM-1964, a 100-pin connector called J1 was used. Rev. A is used with a CB-50-100 adapter instead of a CB-50-80.
