The 5/24 volt DC (TTL) Negative Logic Output module for the Series 90-30 Programmable Logic Controller provides 32 discrete outputs. The outputs are arranged in four isolated groups of eight (A1 - A8, B1 - B8, C1 - C8, and D1 - D8); each group has its own common. The outputs are negative logic or sinking type outputs (i.e., the ON state for a point results in an active low output).

The module has two modes of operation. In the TTL mode, the outputs can switch user loads across +5 VDC (±5%) and are capable of sinking a maximum current of 25 mA per point. In the 12/24V mode, the outputs can switch user loads over the range of +12 through –24 VDC (+20%, –15%) and are capable of sinking a maximum current of 0.5A per point. Two pins are provided on the user I/O connectors for each group common. Each pin has a current handling capability of 3 amperes. It is recommended that connections are made to both pins when connecting the common; however, it is a requirement for high current applications (between 3 and 4 amperes).

Each group can be used in the mode of operation needed to satisfy the load requirements for a particular application. For example, group A can drive TTL loads and group B can drive 12 VDC loads, while group C and D can be reserved for driving 24 VDC loads. It is important to note, however that the effects of electrical noise must be considered when mixing TTL and inductive-type loads.
