GE IC697MDL750E

  • Product Introduction: This is a 16-channel 24VDC relay output module for the GE Fanuc 90-70 PLC platform. The “E” suffix indicates an enhanced variant with improved features such as faster switching, higher current ratings, or additional diagnostics compared to the standard IC697MDL750. It uses electromechanical relays for output switching, allowing it to drive both AC and DC loads. Each channel provides a Form C (SPDT — Single Pole Double Throw) contact configuration with Normally Open (NO), Normally Closed (NC), and Common (COM) terminals.

  • Application Scenarios:
    • High-channel-count output switching in process plants
    • Motor starter control (small motors via contactor relay)
    • Solenoid valve actuation (pneumatic/hydraulic)
    • Alarm and indicator light control
    • Mixed AC/DC load switching (relay contacts are voltage-agnostic)
    • Legacy equipment interfacing where relay isolation is required

    • Relays: Sealed electromagnetic relays with silver-nickel alloy contacts
    • PCB: 4-layer FR-4, conformal coated
    • Snubber: RC network (100Ω + 0.1μF) per relay contact
    • Terminals: Screw-type, 18-22 AWG, tin-plated copper
  • Structural Features:
    • Wide IC697 module (approximately 2x standard width for 16 channels)
    • 16 LED indicators (red) on front panel
    • Screw terminals per channel: NO, COM, NC
    • Two isolation barrier zones visible on PCB
    • DIN-rail mountable
  • Working Principle:
    • The CPU writes to the output register via the Genius Bus backplane. The module’s internal logic energizes the relay coil for the selected channel. The electromagnetic relay mechanically switches the contact from NC to NO. The LED indicates when the relay is energized. The mechanical nature provides galvanic isolation (no electrical connection) between the PLC logic and the load circuit.
  • Installation Requirements:
    • Mount in IC697 chassis (90-70 compatible)
    • Wire loads to COM and NO (or NC) terminals per channel
    • For inductive loads (solenoids, relay coils), use external flyback diode or ensure snubber is active
    • Use 18-22 AWG wire for field connections
    • Connect common ground to PLC chassis ground
  • Usage Precautions:
    • Do not exceed 2A per channel — use external contactor for larger loads
    • Do not switch at maximum frequency — mechanical relays wear out
    • Add external suppression for highly inductive loads (large solenoids, motor coils)
    • Verify AC/DC rating matches your load voltage and current
    • Allow 8ms delay in logic for relay switching time
    • Do not mix AC and DC loads on the same channel — use separate channels
