The GE IC693MDL645E input module provides sixteen discrete input points for connecting field devices to Series 90-30 PLC systems. This module accommodates both sink and source wiring configurations for maximum application flexibility. The GE IC693MDL645E accepts input voltages ranging from 10 to 30 VDC, covering standard 24 VDC industrial sensors. Each input channel includes an optical isolator to protect the backplane from electrical noise and transients. The module filters out brief voltage spikes and contact bounce for reliable signal interpretation. This filtering reduces false triggers in noisy industrial environments.
Input Circuitry and Electrical Specifications
The GE IC693MDL645E employs a high-speed input filter with selectable response times of 1 or 10 milliseconds. This filter allows users to balance response speed against noise immunity for specific applications. Each input draws approximately 7 milliamps at 24 VDC, presenting a light load to field sensors. The IC693MDL645E provides two groups of eight inputs, each with its own common terminal. The module accommodates wiring from 14 to 22 AWG through removable terminal blocks. Its internal design incorporates a 16-bit shift register for sequential data transfer to the CPU. The module’s printed circuit board uses surface-mount components for reliable operation.
The GE IC693MDL645E measures 5.0 inches in height and 2.5 inches in width with a depth of 4.5 inches. This input module weighs approximately 1.1 pounds for easy installation and replacement. The front panel features sixteen green LED indicators, one for each active input channel. The IC693MDL645E draws 45 milliamps from the +5 VDC backplane supply for its internal logic. It also draws 30 milliamps from the +24 VDC field supply for the input circuitry.
Operational Characteristics and Application Suitability
The GE IC693MDL645E operates across a temperature range from 0 to 60 degrees Celsius without performance degradation. This module accommodates relative humidity from 5% to 95% without condensation for reliable service. The input filters maintain consistent performance throughout the module’s service life. Each channel withstands continuous overvoltage up to 35 VDC without damage to the circuitry. The IC693MDL645E also tolerates transient surges up to 500 watts for robust protection.
