GE IC693MDL940 Series 90-30 16-Point Normally Open Electromechanical Relay Discrete Output Module

In stock

Product Introduction:

The IC693MDL940 is a high-reliability electromechanical relay output module manufactured by GE Fanuc for Series 90-30 PLC control systems. It converts digital logic signals from PLC CPU into mechanical contact switching actions to drive AC and DC field loads simultaneously. The module adopts 4 independent isolated groups with 4 NO relay contacts per group, realizing complete electrical isolation between control logic and field equipment. It delivers stable long-cycle switching, strong load adaptability and safe fault isolation performance, matching diverse low-power industrial discrete control scenarios.
