Product Dimensions：

The GE Fanuc IC693MAR590B is a Mixed I/O Module designed for the Series 90-30 Programmable Logic Controller (PLC) system. This specific module is unique because it combines both input and output capabilities within a single slot, making it an efficient choice for systems with limited space. Specifically, it provides 8 points of 24V DC Input and 8 points of Relay Output.

Product Specifications

Module Type: Mixed I/O Module (Discrete)
Series: Series 90-30 PLC
Input Points: 8 points, 24V DC, Positive/Negative Logic (Sink/Source)
Input Voltage Range: 0 to +30V DC
Input Current: $7 \text{ mA}$ per point (typical) at 24V DC
Output Points: 8 points, Relay Output (Normally Open)
Output Voltage Range: 5 to 240V AC or 5 to 30V DC
Maximum Output Current: 2 Amps per point (maximum) and 4 Amps maximum per common
Isolation: 1500V between field side and logic side
Power Consumption: $80 \text{ mA}$ from +5V bus; $125 \text{ mA}$ from relay +24V bus (when all relays are on)
External Power Required: +24V DC is required to operate the relay coils

Product Advantages

Space Efficiency: By combining inputs and outputs into a single module, it saves valuable backplane space, allowing for smaller enclosures or more compact system designs.
Versatile Relay Outputs: The relay outputs provide a high degree of flexibility, as they can switch both AC and DC loads with relatively high current capacities compared to solid-state outputs.
Cost-Effective: Utilizing a mixed module often reduces the total hardware cost by eliminating the need to purchase two separate 8-point modules.
Simplified Spares: Maintenance teams only need to stock one part number to cover both input and output needs for small-scale control loops.

Important Considerations and Precautions

Current Limits: Users must be careful not to exceed the 4 Amps per common limit. Exceeding this can lead to internal trace damage or overheating of the terminal block.
Relay Life: Unlike transistor outputs, mechanical relays have a finite lifespan based on the number of operations and the load type (inductive vs. resistive). Heavy inductive loads should use external suppression to prevent arcing.
External Power: The module requires an external 24V DC power supply to energize the internal relay coils. If this power is lost, the outputs will not function even if the PLC logic is active.
Mounting Restrictions: The module must be seated correctly in the Series 90-30 backplane and secured with the top and bottom screws to ensure consistent electrical contact and vibration resistance.
Logic Polarity: Ensure the field wiring matches the intended logic (Sink or Source) for the DC inputs to avoid incorrect signal readings.

Product Applications

The IC693MAR590B is ideal for small to medium-scale automation tasks where a few sensors and actuators need to be controlled.

Motor Starter Control: Using the DC inputs to monitor "Running" or "Fault" statuses while using the relay outputs to trigger the contactor coils.
Material Handling: Managing simple conveyor belts where inputs monitor photo-eye sensors and outputs control small motors or pneumatic diverters.
HVAC Systems: Controlling fans, dampers, and pumps while monitoring temperature switches or pressure sensors.
Packaging Machinery: Handling intermittent tasks like sealing or labeling where high-speed switching is not as critical as the ability to switch diverse voltage loads.
Lighting and Gate Control: Frequently used in facilities management for scheduled lighting or controlling gate entry systems due to the robustness of the relay contacts.
