Overview

The IOM-1964 is an input/output module that connects to the 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 E-Series controllers have general purpose I/O connections. On a DMC-3425 and 3415 the standard uncommitted I/O consists of: three TTL digital inputs, three TTL digital outputs, and two analog inputs.

The DMC-34x5 with the DB-14064, however, has an additional 64 digital input/output points than the 6 described above for a total of 70 input/output points. The 64 I/O points on the DB-14064 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 identical to the main axes 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.
