GE Fanuc IC655MDL575 / IC655MDL576 / IC655MDL577 Series Five AC Output Module
Grouped and isolated 115/230 VAC triac outputs in 16- and 32-point formats.
Shared Role, Then Model Differences
The three modules switch AC loads with triac outputs and require an external AC source. They differ by channel density, point current and isolation.
IC655MDL575 supplies 16 grouped outputs at 2 A. IC655MDL576 also supplies 16 outputs at 2 A, but isolates each circuit. IC655MDL577 provides 32 grouped outputs at 1 A and requires a separate hot connection for each eight-point group.
Common Specifications and Model-Specific Data
Isolation, Density and Leakage
Triac circuits have off-state leakage and minimum-load requirements. Select the isolated model only where that separation is part of the field design, and verify small loads accordingly.
IC655MDL575
Grouped 16-point AC load bank.
IC655MDL576
Per-circuit isolation for 16 loads.
IC655MDL577
Four separately fed eight-point groups for 32 loads.
Records to Preserve Before Removal
Step 1
Lock out every AC source; one module may contain multiple group feeds.
Step 2
Record isolation boundaries, hot connections, load current and address.
Step 3
Verify terminal keying and the exact 575/576/577 part number.
Technical Questions

They are Series Five triac AC output modules for 115/230 VAC-class loads.
Which of IC655MDL575 / IC655MDL576 / IC655MDL577 isolates each circuit?
IC655MDL576 provides 16 individually isolated 2 A output circuits.
Which of IC655MDL575 / IC655MDL576 / IC655MDL577 has 32 outputs?
IC655MDL577 has 32 one-amp outputs in four groups of eight.
Why should small loads be reviewed for IC655MDL575 / IC655MDL576 / IC655MDL577?
Triac off-state leakage and minimum load values can affect lamps, relays or high-impedance devices.
What must be isolated before servicing IC655MDL575 / IC655MDL576 / IC655MDL577?
All external AC feeds to every group or isolated circuit must be locked out and verified de-energized.
How should leakage-sensitive loads be checked with IC655MDL575 / IC655MDL576 / IC655MDL577?
Test the real de-energized load state and compare it with the documented off-state leakage and minimum-load requirements.
