SCMD

Dataforth offers a broad line of digital input and output modules and accessories providing safe, reliable interfacing to industrial measurement and control applications. When installed near individual field loads, our SCMD series I/O 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.

SCMD miniature digital I/O modules are solid-state devices which send "ON" and "OFF" electrical signals to and from a computer. The input modules, depending on the type selected, 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 SCMD--MIDC miniature input modules are 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. Models with low noise, fast switching, and other special features are also available.

SCMD-MOAC and SCMD--MODC are miniature output modules accepting 5VDC or 24VDC inputs and providing 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 also available.

SCMD-MORO and SCMD--MORC are miniature relay output modules used for switching AC and DC loads up to 125Vrms or 100VDC at maximum 30WDC or 62.5VA.
