Digital I/O Modules

The FLEX I/O module plugs into the terminal base, connecting to the I/O bus and field devices. Since there is no direct wiring to the I/O module, you can remove and insert modules under power, enabling you to change modules without disturbing field wiring, other I/O modules, or system power. This eliminates costly downtime and the inefficiencies of restarting a system.
Modules are available in densities ranging from 8 to 32 points.


  • Digital I/O modules cover a wide electrical range:
    • 120V AC: input, output and isolated input, output modules; 8 and 16 point
    • 220V AC: input and output modules; 8 and 16 point
    • 5V DC: TTL input and output modules, 16 point
    • 24V DC: input, output, and combination modules; sink or source; protected; electronically fused; diagnostic; 8, 16, and 32 point
    • 48V DC: sink input, source output modules; 16 point
    • 125V DC: sink input module; 16 point
    • Relay: sink/source, 8 point
  • Isolated inputs and outputs can be used in applications such as motor control centers, where individual control transformers are used.
  • Protected (P) outputs have electronic protection, which acts to shut the module down in reaction to a short circuit, overload, or over-temperature condition. Recovery from shutdown is automatic upon removal of the output fault. No fault status is provided to the processor.
  • Electronic fused (EP) module acts to open the output when a fault occurs. The “fuse” can be reset by operating a pushbutton, via software, or by cycling the input power. Fault status is provided to the processor.
  • Diagnostic (D) modules detect, indicate, and report the following faults:
    • open input or output field devices or wiring
    • shorted output field devices
    • shorted input or output wiring
    • reverse polarity of user supply wiring
  • Selectable input filter times from <1…60 ms.
  • LED for each channel indicating status of:
    • corresponding input device
    • output signal
  • Extreme environment (XT) versions of standard modules.
