GE A03B-0801-C117 Output Module | 8-Channel 24V DC 0.5A

Reliable Load Control for CNC Systems

The GE A03B-0801-C117 switches DC loads directly from CNC ladder logic. This module provides eight discrete output channels in a compact form factor. Each channel drives solenoid valves, relay coils, or indicator lamps. Consequently, machine builders integrate this unit into tool changers or coolant systems.

Physical and Electrical Specifications

This output module measures 180 mm in height by 40 mm in width. The GE has a depth of 150 mm. It weighs approximately 0.35 kg. The unit contains a single printed circuit board with eight surface-mount relays. A 20-pin ribbon cable connector handles all signal and power interfaces.

The module stores no user data or configuration parameters. It relies entirely on the CNC controller for output states. Furthermore, the GE A03B-0801-C117 uses no battery or capacitor for energy retention. This design eliminates any scheduled maintenance for power storage components.

Output Characteristics and Ratings

Each output channel on the GE A03B-0801-C117 handles 24V DC at 0.5 amps. The total module current does not exceed 4 amps across all channels. Each relay provides optical isolation between the logic and field sides. Therefore, electrical noise from loads does not affect the CNC controller. The module’s response time reaches 5 milliseconds from command to output change.

Status Indication and Diagnostics

Furthermore, this module includes eight red LED indicators on its face. Each LED lights up when the corresponding output channel activates. Technicians can see channel status without lifting cabinet doors. The GE A03B-0801-C117 also provides a power-good LED for the 24V supply. A blown fuse indicator warns users of internal circuit damage.

Installation and Compatibility

This module mounts directly inside GE CNC main racks. It occupies a single slot adjacent to input or CPU cards. The GE A03B-0801-C117 requires a clean 24V DC supply at 0.2 amps for logic. Always disconnect main power before removing or inserting this unit. The module operates reliably from 0°C to 55°C ambient temperature.
