GE WESDAC D10A Control Output Module

Configured for localized discrete command routing and actuator switching in Speedtronic Mark V control system platforms, the GE Fanuc WESDAC D10A (D10A Control Output Module) provides direct physical/electrical execution. It switches electromechanical arrays and solid-state configurations natively at the backplane tier to command external process field elements parallel to master control network platforms.

Hardware Specifications

Industrial Control & Drive Integration

• Backplane Bus Communication Velocity Licences and Relay Interlocking: The module handles state changes through synchronized internal bus links. This structure allows independent coil or gate switching loops to run without introducing transmission delays that could limit backplane bus communication velocity properties assigned to the main core processors.
• Profinet / EtherNet/IP Deterministic Networks Mapping: Channel states and circuit diagnostics are stored in local register addresses. These status registers map to supervisory Profinet / EtherNet/IP deterministic networks via protocol bridge modules, keeping remote SCADA databases synchronized with field output states.
• I/O Density Scaling and Channel Configuration: Providing multiple independent output points per unit reduces the total number of hardware slots needed for digital command execution. This density simplifies panel layout designs and improves overall I/O density scaling inside centralized termination cabinets.

Frequently Asked Questions

Q: What technical behavior manifests if the module experiences a loss of logic supply voltage during an active command sequence?

A: The internal monitoring watchdog drops the bias voltage instantly. This drop forces all output channels to return to their hardware-configured fail-safe de-energized states, preventing unintended field equipment operation during power interruptions.

Q: Can the selectable relay and transistor channels be adjusted or modified while the assembly is under load?

A: No. Modifying channel options requires changing physical jumpers or wire connections on the module circuit board. The main circuit breaker must be locked out before handling internal parts to avoid inductive arcing and component short circuits.
