Product Overview

The SE4304T01 is a DeltaV Analog Output CHARM from Emerson. This CHARM supports 4-20 mA signals with or without HART communication. The SE4304T01 also supports a 0 to 20 mA option for broader compatibility. This device is part of Emerson's Electronic Marshalling solution for distributed I/O. Consequently, the SE4304T01 provides flexible analog output capabilities anywhere in your facility. The CHARM design eliminates traditional marshalling cabinets and reduces overall footprint.

Technical Specifications

Part Number: SE4304T01
Product type: DeltaV Analog Output 4-20 mA HART CHARM

Accuracy Over Temperature Range

The SE4304T01 delivers excellent accuracy across its operating range. Specifically, accuracy is 0.25% of span from 0 to 60°C. Furthermore, accuracy is 0.5% of span from -40 to 70°C. As a result, this CHARM maintains reliable performance in diverse environmental conditions. The SE4304T01 requires no field calibration, which reduces maintenance costs and simplifies commissioning.

Power and Protection Features

Available field power: 20 mA at 15V DC supply into 750 Ω load
Field circuit protection: 24 mA current limiting circuit with field wiring disconnect
CHARM power requirement: 42 mA maximum at 24V DC
CHARM heat dissipation: 0.48 W

The SE4304T01 includes built-in current limiting for output protection. The field wiring disconnect allows safe maintenance without powering down the entire system. Furthermore, the CHARM consumes only 42 mA at 24V DC. Therefore, the SE4304T01 is energy efficient and suitable for dense I/O installations.

HART Communication Support

The SE4304T01 supports HART v7 pass-through for AMS Device Manager. HART v7 variable and device status are available to control functions. HART data update rates are faster than every second. However, update rates depend on HART communication loading and device type. Consequently, the SE4304T01 delivers both analog control and digital device diagnostics over the same two wires.

System Compatibility Requirements

The SE4304T01 CHARM I/O hardware requires specific controller and software versions:

With DeltaV v11.3.1 or later software:
- SD Plus controllers
- SX Controllers
- SQ Controllers

With DeltaV v14.3 or later software:
- MD Plus Controllers
- MQ Controllers
- MX Controllers
- PK Controllers

When assigning CHARMs to MD Plus and SD Plus controllers, evaluate the Time Utilization Chart first. This ensures the additional communication load can be handled by the controller. Furthermore, S-series and M-series controllers can be installed on the same DeltaV Area Control Network in v11 and beyond. PK Controllers can be added in v14.3 and beyond. Control modules can be assigned to any controller. Inter-controller references are fully supported between different controller types.

Installation Guidelines

1. First, install a CHARM I/O carrier in your DeltaV system.
2. Then, insert the SE4304T01 CHARM into an available slot.
3. Ensure the controller meets the minimum software version requirements.
4. Next, connect the field device wiring to the CHARM terminals.
5. The SE4304T01 supports up to 750 Ω load at 20 mA.
6. After that, apply 24V DC CHARM power to the carrier.
