Emerson 396358-02-0 ControlWave Digital Output

The Emerson 396358-02-0, also cataloged as the 396358020 ControlWave Digital Output Module, operates as a dedicated hardware component for high-density discrete command execution within ControlWave RTU and PLC platforms. The board-level sub-assembly drives 16 physical local termination points natively at the hardware tier to actuate external field relays, solenoids, and indicators.

Hardware Specifications

Process Control & Instrumentation Interface

• Channel-to-Channel Isolation and Commutation Protection The 16-point digital card incorporates dedicated internal optical and galvanic barriers that establish rigid channel-to-channel isolation parameters between the discrete output switches and the central logic tracks. This physical configuration prevents external ground loops or high-voltage inductive transients from back-propagating into the system architecture or disrupting adjacent node tracks.
• 4-20 mA HART Loop Protocol Coexistence The output switching paths are engineered to minimize high-frequency electromagnetic emissions during contact state transitions inside shared marshaling enclosures. The module suppresses localized electrical noise, allowing adjacent slots to run high-sensitivity analog signaling systems utilizing the 4-20 mA HART loop protocol without experiencing cross-talk or inductive signal degradation.

Frequently Asked Questions

Q: How does the local termination connector block design alter field wiring and module servicing?

A: The integrated local termination connector permits pre-wiring of the 16 discrete field loops directly onto the terminal assembly. This configuration decouples the physical field wiring harness from the active internal electronics, allowing the main card to be extracted or replaced without breaking down individual wire terminations or dropping adjacent loops.

Q: What actions are executed by the module if an external inductive load generates a reverse-voltage transient?

A: The module's internal circuitry incorporates dedicated solid-state clamping diodes natively at the hardware tier. When an inductive load (such as a field solenoid or relay coil) de-energizes, the clamping diodes channel the resulting reverse-voltage kickback safely away from the primary switching transistors, preventing chip-level dielectric breakdown.
