More Information

Overview Manuals Environmental Ratings Status & Address Safety & Protection Field Wiring

Features:

  • Each of the sixteen isolated outputs has its own fast-blow protective fuse.
  • The removable front terminal block keeps the field conductors together during a module exchange.
  • A 10 A module ceiling supports distributed loading across the individual 2 A output circuits.
The permissible number of active channels depends on both current per point and ambient temperature. At heavier point loading, fewer circuits can remain energized as the cabinet approaches the top of the operating range.

Switching completes in less than one millisecond when turning on and in less than ten milliseconds when turning off at 60 Hz. This timing lets a technician separate expected triac response from slower field-device movement.

The field supply must remain within the supported AC window and frequency range, while the module also limits the peak voltage presented to its output stage. Source selection therefore belongs to the electrical design rather than the PLC backplane alone.

Series Five cabinet limits

  • Operating temperature: The surrounding air at the outside of the rack may range from 0 to 60°C without forced-air cooling.
  • Storage exposure: An unpowered module may be stored from -20 to 70°C.
  • Humidity control: Keep relative humidity between 5% and 95% and prevent condensation.
  • Atmosphere: Install the rack where corrosive gases are absent.

Using the dual-purpose front indicators

  • Point mapping: One LED corresponds to each of the sixteen output circuits.
  • Logic state: Every indicator follows the commanded ON or OFF condition of its associated point.
  • Address display: A program command changes the indicator function to show the module starting I/O address.
  • Commissioning check: Compare the displayed start address with the configured rack allocation before tracing an unexpected output point.

Electrical safeguards for isolated AC channels

  • Dielectric withstand: Series Five I/O circuits are rated for a 1500 VAC, one-minute dielectric test.
  • Insulation resistance: The common I/O requirement exceeds 10 megohms at 500 VDC between chassis and power source.
  • Arc performance: The I/O construction meets the NEMA ICS 2.230.40 showering-arc test.
  • Noise immunity: The Series Five I/O requirement covers 1 ms, 1 kV Sanki pulses.

Connecting individually powered output circuits

  • Terminal access: Field conductors land on the removable block at the front of the module.
  • Channel connection: Two terminals are assigned to every output circuit.
  • Source flexibility: Individual circuits may use different compatible AC supplies, including separate phases.
  • Load power: The user provides every AC source needed by the connected output loads.
  • Circuit separation: Maintain the source-relative isolation shown for each channel instead of introducing an unintended shared connection.
Description
The General Electric IC655MDL576 115/230 VAC Isolated Output Module, 2 Amp, 16 Circuits is a Series Five PLC rack module that controls externally powered AC loads through sixteen separate output paths.

Unlike a shared output bank, every channel on IC655MDL576 is isolated from the other circuits relative to its AC source. Two field terminals are assigned to each output, so a cabinet design can place individual loads on different compatible AC sources or phases without using a common module feed.

Sixteen front indicators give IC655MDL576 a direct point-by-point view of the commanded output state. A program-controlled display mode uses those indicators to present the module starting I/O address, helping technicians relate the rack allocation to the connected field circuits.

Because IC655MDL576 uses solid-state triac switching, load selection must consider startup demand, off-state behavior, and very light loads as well as steady current. Its output-points-versus-temperature curve makes simultaneous channel loading part of the cabinet thermal plan rather than a fixed assumption.

Technical notes
For IC655MDL576 rack power budgeting, include the 650 mA maximum base load and another 35 mA for every energized output; before replacing the module, also confirm the fuse and AC source assigned to every field circuit.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can an AC load connected to IC655MDL576 show voltage after the output is turned off?
IC655MDL576 uses triac outputs with finite off-state leakage, so a high-impedance meter or very light load can show residual voltage; verify the reading under a suitable test load.
What should be checked if an IC655MDL576 fuse opens again after replacement?
For IC655MDL576, isolate the field source and inspect the load and conductors for a short, then compare startup current with the circuit inrush envelope before fitting another 3 A fast-blow fuse.
How should IC655MDL576 be evaluated when many outputs operate in a warm cabinet?
Use the IC655MDL576 output-points-versus-temperature curve with the actual current per energized point; the permitted simultaneous count falls as ambient temperature and point loading rise.
Why might IC655MDL576 control the wrong field point after a rack replacement?
Command the IC655MDL576 address-display function, compare the indicated starting I/O address with the PLC allocation, and then trace the corresponding terminal before changing the program.
Can different IC655MDL576 circuits be connected to different AC phases?
IC655MDL576 provides two terminals and source-relative isolation for each output, allowing compatible separate AC sources or phases when the cabinet wiring keeps every circuit correctly segregated and identified.
What is the safe sequence for replacing IC655MDL576 while retaining field wiring?
Before removing IC655MDL576, switch off rack power and every user-supplied AC source, prove the terminals de-energized, label and detach the removable block, reinstall in the correct slot, and test the loads after restoration.
Why should the IC655MDL576 backplane load be recalculated during an upgrade?
IC655MDL576 draws rack 5 VDC current before field loading is considered and adds consumption for energized points, so the complete Series Five base power budget must be checked after other modules change.
