Product Description

The IC693MAR590 (Revision B) is a 120V AC Input/Output Mixed Module. It features 8 Input points and 8 Relay Output points. As part of the Series 90-30 line, it is designed for modularity and is compatible with all standard 90-30 backplanes. The “B” version indicates a specific hardware revision that often includes updated components for better reliability over the original “A” version.

Product Parameters

Product Advantages

• Space Efficiency: By combining inputs and outputs into a single slot, it allows for smaller PLC racks and enclosures, reducing overall hardware costs.

• Versatile Switching: Because the outputs are Relays, they can switch both AC and DC loads and are not polarity sensitive, offering more flexibility than Triac or Transistor outputs.

• Individually Isolated Commons: The module typically provides multiple commons, allowing you to run different circuits or phases on the same module.

• Legacy Reliability: The Series 90-30 is legendary for its “bulletproof” durability in harsh industrial environments.

Key Considerations (Precautions)

• Relay Lifespan: Unlike solid-state outputs, mechanical relays have a finite number of cycles. Avoid using this module for high-speed PWM (Pulse Width Modulation) or extremely frequent switching.

• Inrush Current: When switching inductive loads (like large motor starters or solenoids), ensure the inrush current does not exceed the 2A rating, or use external suppression (RC snubbers).

• Fuse Protection: This module does not have internal fuses for the outputs. It is highly recommended to install external fuses to protect the module from field-side short circuits.

• Hot Swapping: Do not insert or remove this module while the PLC rack is powered up, as it can cause electrical arcing or damage the backplane interface.

Product Applications

The IC693MAR590B is ideal for general-purpose control where high-speed switching is not required:

• Motor Control Centers (MCC): Ideal for “Start/Stop” logic where 120V AC control signals are the standard.

• Lighting Systems: Controlling industrial lighting banks via the relay outputs.

• Pump Stations: Monitoring float switches (inputs) and triggering pump contactors (outputs).

• Material Handling: Detecting presence via limit switches and activating pneumatic valves or diverters.
