IC693MDL330 GE Fanuc Series 90-30 AC Output Datasheet & Manual

GE Fanuc IC693MDL330 Series 90-30 AC Output Module

The GE Fanuc IC693MDL330G, also cataloged as the IC693MDL330 Discrete Output Module, operates as a dedicated hardware component for digital switching and ON/OFF control of external AC loads within Series 90-30 PLC platforms.

Hardware Specifications

Backplane Bus Communication & Firmware Flash Compatibility

The IC693MDL330G interfaces directly with the Series 90-30 parallel backplane, receiving logical states from the main processor during the output update phase of the scan cycle. The digital filtering and optical isolation logic protect internal backplane bus communication velocity from being compromised by high-voltage field transients or inductive switching noise.

While this module consists of basic solid-state switching components without internal microprocessors, ensuring strict firmware flash compatibility across adjacent smart modules and the CPU on the same rack layout is required. This preventative measure limits the risk of phase-angle sync delays or timing drops during rapid periodic data exchange sequences under maximum resistive or inductive load limits.

Frequently Asked Questions

Q: Does the IC693MDL330G support hot-swapping or Run-Time Module Insertion and Removal (RIUP)?

A: No. The Series 90-30 chassis and backplane mechanics do not support hot-swapping or RIUP. The primary power distribution to the baseplate assembly and the field-side AC voltage rails must be entirely disconnected before inserting or removing the module to avoid hardware failures or contact arcing.

Q: What are the consequences of dropping below the minimum load current specification?

A: The solid-state switching circuits inside the module require a minimum continuous load current of 100 mA to maintain a fully latched and stable conduction state. If a connected device draws less than 100 mA, the output switch may fail to turn off or exhibit erratic voltage leakage across the field terminals.

Q: How are internal electronic overloads handled by this output module?

A: The IC693MDL330G relies on external fused protection for individual field circuits. If an external short circuit or an inrush event exceeding 20 A per cycle occurs, external quick-acting fuses must be deployed to isolate the channel before the thermal dissipation thresholds of the module are breached.

Field Installation Guidelines

• Chassis Securement: Verify that all incoming system and field electrical supplies are off. Slide the backplane connector into the chosen universal Series 90-30 baseplate slot, verify the upper hinge hooks lock onto the chassis frame, and snap the bottom retention catch into its seat.
• AC Output Terminations: Connect the 120/240 VAC field power lines to the output terminal block, matching wire cross-sections to the 2 A per point threshold. Ensure neutral and line conductors match the physical loop diagrams.
• Conduit Segregation: Route all high-voltage AC output wires through dedicated, isolated cable paths separate from low-voltage DC signals, instrumentation lines, and serial network loops to minimize cross-talk.
• Thermal Convection Clearances: Maintain horizontal orientation of the rack assembly with unhindered spacing boundaries above and below the module housing to allow rising air currents to clear internal heat from the switching components, keeping local temperatures under 60 deg C.
