GE IC693MDL646D Discrete DC Input Module

FAQ

Q1: What is the GE Fanuc IC693MDL646D used for?
The IC693MDL646D is used to collect 24 VDC digital input signals from field devices and transfer their ON/OFF status to a GE Fanuc Series 90-30 PLC CPU.

Q2: How many input channels does the IC693MDL646D provide?
The module provides 16 digital input channels arranged as one input group sharing a common terminal.

Q3: What voltage signals can the IC693MDL646D accept?
The module accepts 0 to 30 VDC input signals, with 24 VDC as the nominal operating voltage.

Q4: Does the IC693MDL646D support both positive and negative logic?
Yes. The module can be configured for either positive logic or negative logic input wiring, providing flexibility for different field device arrangements.

Q5: What types of devices can connect to the IC693MDL646D?
The module can interface with devices such as proximity switches, push buttons, selector switches, limit switches, and relay contacts.

Q6: Does the IC693MDL646D provide electrical isolation?
Yes. The module provides 1500 VAC isolation between the field input circuits and the PLC logic side to improve system protection.

Q7: What are the ON and OFF voltage thresholds of the IC693MDL646D?
The input turns ON when the voltage is between 11.5 and 30 VDC and remains OFF from 0 to +5 VDC.

Q8: What should be checked before replacing an IC693MDL646D module?
Before replacement, verify the Series 90-30 rack compatibility, input voltage level, field wiring configuration, common terminal connection, PLC hardware configuration, and replacement module revision to ensure proper operation.
