Emerson DeltaV SE4302T02 Inductive Load Output CHARM

Configured for switching high-current DC field circuits in DeltaV Electronic Marshalling platforms, the Emerson DeltaV SE4302T02 (SE4302T02 Isolated 24 VDC Inductive Load Output CHARM) provides direct physical/electrical execution.

Hardware Specifications

Process Control and DCS Loop Execution

• Channel-to-Channel Isolation Control: Features dedicated galvanic physical layer separation, blocking electrical transient surges and loop feedback from spreading into adjacent logic components.
• 4-20 mA HART Loop Parallel Isolation: Eliminates signal crosstalk on nearby analog input or output channels by isolating high-amplitude discrete switched currents from sensitive HART communication loops.
• Inductive Load Suppression: Integrated solid-state output circuitry is designed to clamp inductive voltage spikes generated by switching 24 VDC solenoids, relays, or magnetic contactors without needing external flyback diodes.
• Low Heat Dissipation Design: Limits thermal generation to 0.46 W under worst-case operation, preventing internal cabinet heat build-up within high-density Electronic Marshalling baseplates.

Frequently Asked Questions

Q: Can the SE4302T02 module switch inductive loads directly without external suppression diodes? A: Yes. The SE4302T02 is designed to drive 24 VDC inductive loads directly and includes built-in voltage clamping circuitry to manage inductive kickback currents safely.

Q: What is the maximum continuous current rating for the output of the SE4302T02? A: The module supports a maximum continuous load current of 1.0 A over an output voltage range of 4 to 32 VDC.

Q: What is the off-state leakage current of this module? A: The off-state leakage current is restricted to a maximum of 1.0 mA, preventing low-power field relays from failing to drop out.

Field Installation Guidelines

• Baseplate Alignment: Align the rear terminal guides of the SE4302T02 with the designated slot on the CHARM baseplate. Press down firmly until the retention clips engage on both sides to establish a positive connection to the backplane power bus.
• Field Wiring and Shielding: Strip field conductor ends to the specified length before clamping them into the terminal block screw terminals. Route 24 VDC discrete power switching lines separately from low-voltage analog signal lines to minimize electromagnetic coupling.
• Thermal Venting: Keep a minimum vertical clearance of 100 mm above and below the horizontal baseplate assemblies to promote chimney-effect ventilation inside the enclosure, ensuring internal temperatures remain within the -40 to +70 deg C range.
