The Series 90-30 offers more than 100 different I/O modules, and new options keep coming.  New 48VDC I/O modules are now available.They are ideal for Utility substation automation, running on 48VDC control.

This 48 volt DC Positive/Negative Logic Input module (IC693MDL648) provides 16 input points in one group with a common power input terminal.  The on and off response times for this module are 1 mSec maximum.  This input module is designed to be used in either positive logic or negative logic applications.  Input characteristics are compatible with a wide range of user-supplied input devices, such as pushbuttons, limit switches, and electronic proximity  switches.

The 24/48 volt DC Positive Logic 0.5 Amp Output module (IC693MDL748) provides 8 output points in one group with a common power input terminal.  This output module is a positive logic type in that it sources current to the output devices from the user positive power bus.  The output characteristics are compatible with a wide range of user-supplied output devices, such as motor starters, solenoids, and indicators.  Power to operate output devices must come from an external power 48VDC source supplied by the user.  This module is rated for either 24 or 48 volt DC positive logic 0.5 Amp output applications.
