Emerson 396358-02-0 ControlWave Digital Output Module

Configured for discrete logic switching and digital payload routing in Emerson ControlWave architectures, the Emerson 396358-02-0 (396358-02-0 Digital Output Module) provides direct physical/electrical execution.

Hardware Specifications

Channel-to-Channel Isolation and Discrete Switching Control

The 396358-02-0 module incorporates channel-to-channel isolation across its 16 discrete output channels to isolate internal ControlWave backplane logic from field-side voltage transients and inductive switching spikes. Active noise suppression circuitry prevents inductive kickback from solenoid valves and interposing relays, maintaining signal integrity and preserving backplane voltage levels across the local bus structure.

Frequently Asked Questions

Q: Does replacing the 396358-02-0 module require shutting down the ControlWave backplane power supply?

A: Yes, system power to the backplane rack must be isolated prior to removing or inserting the module to prevent electrical arcing and logic corruption on the local bus.

Q: What protective measures should be applied when driving inductive field loads from the local termination connector?

A: Flyback diodes must be installed across external DC inductive loads (such as relay coils or solenoids) to clamp high-voltage spikes and enforce channel-to-channel isolation boundaries.

Field Installation Guidelines

1. Turn off backplane power and verify zero voltage across the rack connectors before inserting the module.
2. Align the module edge guide with the ControlWave rack chassis and slide the unit until the rear connector seats firmly into the backplane socket.
3. Wire field outputs to the local termination connector, ensuring discrete signal cabling is routed separately from high-voltage AC lines.
4. Ground all cable shields to the local Instrument Earth (IE) bus bar to minimize electromagnetic interference across field channels.
