Emerson 396358-02-0 ControlWave Digital Output Module

The Emerson 396358-02-0, also cataloged as the 396358-02-0 Digital Output Module, operates as a dedicated hardware component for discrete field device actuation within ControlWave PLC platforms. The module executes switching control commands across 16 independent open-collector digital output channels, driving external relays, solenoids, and field status indicators via local termination assemblies.

Hardware Specifications

FOUNDATION Fieldbus and Channel Isolation

The digital output architecture features channel-to-channel isolation to prevent field ground potential variances from coupling into the internal logic circuitry. When deployed alongside 4-20 mA HART loop protocol modules and FOUNDATION Fieldbus segments on a common backplane structure, the internal output drivers isolate switching transient spikes and inductive kickback voltages from sensitive analog communications. Cold junction compensation models and onboard hardware filtering maintain stable state execution across fluctuating operating ambient temperatures inside local control cabinets.

Frequently Asked Questions

Q: What is the maximum current rating per channel for the 396358-02-0 open-collector outputs?

A: Each of the 16 independent output channels supports a maximum continuous sink current capacity of 500 mA DC.

Q: Are flyback diodes required when driving inductive loads with this module?

A: External inductive loads such as solenoid coils and interposing relays require external surge suppression diodes installed directly across the load terminals to prevent high-voltage transients from damaging the open-collector output transistors.

Q: Can the 396358-02-0 module be hot-swapped while the ControlWave backplane is energized?

A: No. Power to the chassis backplane bus and field loop voltage power supply must be disconnected before removing or inserting the module card into the slot.

Field Installation Guidelines

1. De-energize backplane rack power and external load power supplies prior to hardware installation.
2. Align the module card edges with the targeted chassis slot guide rails inside the ControlWave base rack.
3. Slide the card into the slot until the backplane connectors seat completely, then lock the upper and lower housing latches.
4. Connect external DC field power and discrete load conductors to the 16-point local terminal block, observing correct output polarity.
5. Route low-voltage digital output wiring separate from high-voltage AC cables to prevent inductive noise coupling.
6. Verify that all field cable drain shields are tied to the primary enclosure single-point ground bar before applying system power.
