Description

Emerson SE4003S2B1

Technical Specifications: Rated power supply: 24 VDC Galvanic isolation between field side and system side Operating temperature range: 0 ℃ to 60 ℃ Storage temperature: -40 ℃ to 85 ℃ Relative humidity:5% to 95% non-condensing

Functional Features: Provide 24V loop power supply for two-wire field transmitters. Each channel has independent overcurrent protection circuit. LED indicators display power and channel fault status. Support hot plug and extraction of matched S-series I/O cards. Built-in EMI filter suppresses electromagnetic interference. Reserved test jacks for signal measurement during maintenance.

Application Scenarios: Chemical process control system, oil and gas pipeline monitoring, oil refining plant automation, pharmaceutical batch control, food and beverage production control, power plant auxiliary control.

Performance Parameters: Surge withstand capability: 2kV common mode surge Maximum per channel loop current: 20mA for analog signal loop Vibration resistance:10 Hz ~150 Hz,1g Shock resistance:15g peak,11ms MTBF: 235000 hours

Material Composition: Base housing: UL94-V0 flame retardant thermoplastic. Terminal screws: nickel-plated brass. PCB substrate: FR4 epoxy glass fiber board. Filter and protection components encapsulated with epoxy compound. Mounting spring clip: stainless steel.

Structural Features: 35mm DIN rail snap mounting design. Front panel equipped with LED indicator window and channel marking area. Card socket on top surface for I/O card insertion. Screw terminals arranged on front lower area. Built-in positioning structure prevents wrong card installation. Ventilation slots on shell for passive heat dissipation.

Working Principle: Field instrument signals connect to screw terminals. Signals pass through EMI filter and surge protection circuit, then transmit to DeltaV I/O card installed on the base. The I/O card converts field analog or digital signals into digital data and sends data to DeltaV controller. The terminal block provides 24V loop power supply for two-wire transmitters on site. Built-in fault detection circuit feeds back channel abnormal state to controller.

Installation Requirements: Mount on standard 35mm DIN rail inside control cabinet. Reserve 20mm space for ventilation. Separate analog signal cables and power cables in different wiring channels. Tighten terminal screws with torque 0.5 N·m to 0.7 N·m. Complete wiring work before powering on the system. Keep away from high-power frequency converter cables.

Precautions for Use: Do not use in explosive hazardous areas without corresponding explosion-proof certification. Do not apply voltage exceeding rated value to signal terminals. Wear anti-static wristband when handling the module. Regularly clean dust accumulated on terminal base surface. Replace the terminal block immediately if shell cracks or burn marks appear.
