GE IC693MDL930H Relay Output Module

Product Dimensions：

The GE Fanuc / Emerson Automation IC693MDL930H is an isolated Isolated Relay Output Module belonging to the widely used Series 90-30 PLC family. It acts as an interface between the PLC’s low-voltage logic control and higher-powered field devices.

Product Detailed Description

The IC693MDL930H provides 8 isolated output channels for controlling a variety of load devices, including motor starters, solenoids, and indicators. Because each channel is electrically isolated from the others, the module can control loads powered by different voltage sources or phases within the same system. The “H” suffix designates the specific hardware revision level, incorporating minor design updates while maintaining full backward compatibility.

Technical Parameters

Product Advantages

• Complete Channel Isolation: Every relay contact is electrically independent. This allows for mixing AC and DC circuits or different phases across adjacent points without interference.
• High Switching Capacity: Able to handle up to 2.0 Amps per point, removing the need for external interposing relays on medium-duty industrial loads.
• Clear Diagnostic Indicators: Equipped with a front-facing LED strip that gives immediate visual confirmation of the ON/OFF state of each logic-side circuit.
• Easy Field Maintenance: Features a removable terminal block, allowing for quick module replacement without having to disconnect individual field wires.

Important Considerations & Precautions

• Inductive Load Protection: Relay contacts can degrade quickly due to arcing when driving inductive loads (e.g., solenoids, contactors). External suppression circuits, such as an RC snubber for AC or a flyback diode for DC, are highly recommended.
• Fused Protection: The module does not feature internal fuses. To protect the module and your wiring from field short-circuits, install external fusing for each output channel.
• Inrush Current Limits: Ensure that the surge or inrush current of the load device does not exceed the maximum peak rating of the contacts, even if the steady-state current is well below 2.0 A.
• Hot Swapping: Do not insert or remove this module from the PLC backplane while the chassis power is turned on; doing so can cause data corruption or damage the backplane components.

Product Applications

The IC693MDL930H is widely used in legacy and modern retrofitted automation panels across multiple industries:

• Industrial Facilities: Direct control of large pilot lights, audible sirens, and small localized heating elements.
• Motor Control Centers (MCC): Acting as the pilot signal to trigger high-capacity motor starters and contactors.
• Water Treatment: Actuating pneumatic and hydraulic solenoids for valve control sequences.
• Infrastructure Panels: Interfacing with building management systems or HVAC dampers requiring voltage-free contact closure.
