B1 Main Units

  1. ：R ─ Relay output；T ─ Transistor SINK(NPN) outputJ ─ Transistor SOURCE (PNP) output

    2. ：2 ─ built-in RS232 port；U ─ built-in USB port (non-standard)

  2. ：AC ─ 100~240VAC power supplyD12 ─ 12VDC power supply

    D24 ─ 24VDC power supply

    4.：Blank ─ Standard；–C ─ add in RTC

    5. The unmarked frequencies of Digital Input (DI) or
    Digital Output (DO) are low speedd.
