DIO-24 DIO-48 DIO-144 / DIO-96 DIO-64

  24/48/96/144 BIT OPTO-22 compatible DIO Board
DIO-64  32DI+32DO+Timer;

Functional Description
The DIO-144 Provides 144 TTL digital I/O lines. THe DIO24/48/96 provides 24/48/and 96 IO lines. All boards emulate 8255 mode 0 and has an increased output current capability of 15 mA (source) and 64 mA (sink), allowing to control LED, relay, etc. The DIO 24 has 3 8 bit ports while DIO-144 consists of eighteen 8 bit bi-directional ports and 2 input lines for interrupt enable and interrupt. The 8 bit ports are named port A(PA), port B(PB), port C(PC). The port C can be split into two four bits. All ports are configured as inputs upon power-up or reset. The DIO-144 use 4 I/O address. The base address is selectable from 200 to 3FF hex. The interrupt signal can be connected to any of the interrupt levels 2 through 7.

Functional Description
The DIO-64  provides 32 digital  input channels , 32 output channels and 6 counter/timer channels The DIO-64 consists of two 16 bit input port and two 16 bit output port  . The user can use the  DB-16P ( or 782 series ) to. Connect the input port (CN2,CN4) for isolation purpose. The user can use DB-16R (or 785 series) to interface to the output port (CN1,CN3) for relay control. There are four clock source , 2M , 1M , 500K , 250K , on the board . The user can choose any one by jumper setting .The user can take the frequency from the soldering pad. On board Timer/Counter provides 3 channel for frequency measure , event counting and pulse generation. The optional 8254 provides 3 channel for interrupt use.
