I/O CARD

Look at picture of the I/O card.

This COMMANDER I/O function card interfaces 8 digital input signals to a companion Base/Expansion cardfile assembly.

Signals may be either logic common, +DC, or AC in nature, and are fully isolated. Signals greater than 24V require conditioning before presentation to the I/O card input terminal. These inputs can also be used to process low-speed pulsing signals as well as certain encoding signals.

SPECIFICATIONS

__________________________________________

Functional

• Inputs per card: 8 (sink or source signals; however, source signals required if optional LEDs are to illuminate as intended)
• Commons per card: 8 (isolated)
• ON voltage: >6.5V

__________________________________________

Operating power

• 10-14VDC input power, from Base assembly
• Typical logic current drain 6mA
• Optional LED indicators draws 3mA each when turned on

__________________________________________

Transient protection

• Meets or exceeds IEEE C37.90A-1987
  surge withstanding specification

__________________________________________

Operating environment (electronics)

• Standard -10 to +70°C temperature
• 0 to 95% relative humidity (non-condensing)

COMMON INPUT VALUES

Higher voltage levels may be found for indication signals. This is accommodated by adding an external voltage dropping resistor in series with the plus terminal of the card. The nominal resistor values for various voltage levels are:

SIGNAL       R-VAL        ADD'L.       

                          SPECS        



48VDC        6.8K         CC 5% 1/4W   



125VDC       22K          CC 5% 1W     



120VAC       22K          CC 5% 1W     



240VAC       44K          CC 5% 2W     

Use of the Universal Termination Assembly, or equivalent, is recommended when status signals exceed 48V.
