PCO 01 board is a very powerful I/O module capable to drive 32 output lines on a standard connector.

Output section is optocoupled so that to warrant the galvanic separation between the external world and the on board electronic.

Each output line is provided with its own LED that visualizes the logic status of the line itself. A LED turns on when the respective output signal is actived. There is also a special circuitery that warrants the Reset condition for all the outputs during the power on. It is also possible to unmatch the outputs Reset from the CPU card Reset acting on Dip-Switch DIP1. By unmatching the PCO 01 Reset from the Master Reset, it is possible to keep the output signals in a Latch condition even when the main CPU is reset.

PCO 01 is connected to the external world through two Standard Abaco® I/O connectors. This warrants a correct I/O interchange amogst the peripherals availabe in the ABACO® listing. To ease the operations of cable mounting and connection of wires from the external world, a set of modules capable of mounting on DIN rack has been created; these modules belong to FBC xxx family. In detail these modules allow to unravel the wires coming from the external Flat-Cables making them available on comfortable quick release screw terminal connectors. There are also FBC modules designed specifically for connections of output cards. Remarkable are FBC 134; FBC 234; etc. These modules are provided with quick release standard connectors and are compatible with, for example, connectors of ZBx xxx serie.

To warrant the with maximum security the outputs status, especially during the delicate phase of power on, a specific circuitry keeps all the outputs disactived until, section by section, it receives the specific write abilitation command. This prevents the possibility of undesired oscillations on the output signals when power supply is not reliable.

PCO 01 peripheral board can work both matching with 8 bit CPU (please refer to GPC® F2, GPC® 15A, etc), and 16 bit CPU (for example GPC® 68, GPC® 97, etc). The choice of BUS width is made by a Dip-Switch, with a visual signalation of the option set.
