PC OPTO DIO 48D SINK
A full length card providing 24 input and 24 output high current, high voltage lines with 2500 Volts opto isolation. The 48 i/o lines, with isolated ground and external power input lines, are accessible from the edge connector, a 50 way ‘D’ connector for greater shielding. Fast TTL buffers and opto isolators allow a maximum throughput of 150kHz. Each input line is current limited and reverse connection protected so ensuring long term use in an industrial environment. OPTO DIO48 requires an external power input to supply the isolated side of the opto circuit range 17.5 – 35Volts. The 48 i/o lines, arranged as 6 eight bit port registers with one read/write watchdog register, occupy 8 i/o locations at base address in the range 200-3FF Hex, default=308H. Software enabled interrupts on input lines Port C#2 bits 0 and 3.
