SCMD Series
Isolated Digital I/O Modules
ISOLATED SCMD DIGITAL I/O MODULES
Dataforth offers a broad line of digital input and output modules and accessories providing safe, reliable interfacing to industrial measurement and control applications. Installed near individual field loads, SCMD modules create a rugged protective isolation barrier, effective to 4kV, between the field and computer system.

Use of these modules can also reduce field wiring costs while establishing an economical, manageable approach for system expansion and repair.



THE SCMD SERIES
SCMD miniature digital I/O modules are solid-state devices which send ON and OFF electrical signals to and from a computer.
  • Input modules convert AC or DC voltages to DC logic signals and send them to the computer system
  • Output modules work in the opposite direction, switching either AC or DC circuits on or off in response to logic-level voltage commands from the computer
SCMD modules are available in miniature versions of four basic types: AC input, DC input, AC output, and DC output.

SCMD-MIAC and -MIDC
  • Miniature input modules used for sensing ON and OFF AC or DC voltage levels in the ranges 10-60, 90-140, and 180-280VAC and 3.3-32 and 10-60VDC
  • Low noise, fast switching, and other special features are available
SCMD-MOAC and -MODC
  • Miniature output modules accept 5VDC or 24VDC inputs and provide several different output ranges, including 12/24 to 140/280VAC and 0/3/5 to 50/60/200VDC
  • Fast switching and other special options are available
SCMD-MORO and -MORC
  • Miniature relay output modules used for switching AC and DC loads up to 125Vrms or 100VDC at maximum 30WDC or 62.5VA
