SE4302T02 Emerson DeltaV 24 VDC Isolated Digital Output CHARM

Product Description

The Emerson SE4302T02 is a 24 VDC Isolated Digital Output CHARM designed for the DeltaV Electronic Marshalling system. It switches DC output signals to control field devices such as solenoid valves, relays, and inductive loads. Furthermore, it provides galvanic isolation between control-side and field-side circuits, together with current-limiting and thermal shutdown protection for field circuit fault handling.

Technical Specifications

Output Function and Load Control

The SE4302T02 provides a discrete output channel for switching 24 VDC field devices. The output voltage range of 4 to 32 VDC defines its supported operating range, while the 1.0 A continuous current rating specifies the maximum sustained output load. Meanwhile, the module supports an inrush current of 2 A for less than 100 ms to accommodate short-duration load startup demands.

Its output behavior supports momentary and continuous pulse operation. These functions allow the control system to issue discrete switching commands according to the configured control strategy.

Electrical Isolation and Circuit Protection

The module provides galvanic isolation between the field output and control-side circuitry, with an isolation test voltage of 1000 VDC. This separation helps limit the transfer of electrical disturbances between the connected field circuit and the control system.

In addition, the SE4302T02 incorporates a 4 A current-limiting circuit and thermal shutdown with automatic reset. It also supports field wiring disconnect protection. These functions help manage overload and thermal fault conditions in connected output circuits.

Installation and System Integration

The SE4302T02 mounts on a CHARM Baseplate within the DeltaV Electronic Marshalling architecture. Its CHARM power requirement is specified as 22 mA maximum at 24 VDC, with power dissipation of 0.46 W. Therefore, these electrical requirements should be considered when checking the available CHARM power budget.

Frequently Asked Questions

Q: What field devices can the SE4302T02 control?

A: It is designed for 24 VDC inductive loads, including solenoid valves, relays, and similar DC field devices, subject to the specified output current limits.

Q: What is the difference between continuous output current and inrush current?

A: The continuous output current is rated at 1.0 A. The module also supports a short-duration inrush current of 2 A for less than 100 ms.

Q: What protection functions does this CHARM provide?

A: It includes galvanic isolation, a 4 A current-limiting circuit, thermal shutdown with automatic reset, and field wiring disconnect protection.
