Functional Features High‑efficiency AC‑DC conversion circuit delivers steady 24VDC power for all modules on DeltaV rack backplane.
EMI filter circuit eliminates high‑frequency noise from power grid and prevents interference from entering control backplane.
Multi‑dimensional hardware protection circuit cuts off DC output instantly once electrical parameters exceed safe thresholds.
Continuous sampling circuit monitors output voltage, load current and internal component temperature of the module.
Hot‑swap mechanical structure supports module replacement under non‑critical operating conditions without shutting down the whole control rack.
Redundant parallel operation realizes seamless power switching and maintains continuous operation of DeltaV control system.
Front panel LED lights directly display running status and fault alarm state of the power module.
Application Scenarios DeltaV DCS control cabinets deployed in chemical plants, oil refineries, natural gas processing stations, pulp and paper factories and thermal power plants.
It serves as power source for DeltaV main control rack to provide stable DC power supply for DeltaV controller, analog and digital I/O modules and communication modules.
Performance Parameters Power conversion circuit maintains stable DC output within full rated working temperature range.
Output voltage ripple stays within specified tolerance under full load working condition.
Protection circuit triggers protection action immediately once abnormal electrical parameters appear.
Diagnostic circuit captures power supply faults and uploads alarm events without delay.
EMI filter effectively suppresses high‑frequency electromagnetic interference from industrial power grid.
Material Composition Flame‑retardant black engineering plastic front housing.
Multi‑layer flame‑retardant glass‑fiber epoxy printed circuit board.
AC‑DC conversion power chips, sampling monitoring microprocessor, EMI filter components and LED status indicators.
Gold‑plated copper alloy backplane connector with anti‑oxidation coating.
High‑temperature resistant power capacitors and power semiconductor switching devices.
Metal heat sink for heat dissipation of high‑power components.
Structural Features Compact plug‑in card size matching standard DeltaV rack slot dimension.
Front panel integrates power normal indicator and fault alarm LED lamps.
Built‑in guide rails and spring mechanical latch fix the module firmly inside control rack and resist cabinet vibration.
Rear gold‑plated multi‑pin connector completes electrical connection with DeltaV rack backplane.
Internal metal heat sink absorbs heat generated by power conversion components.
Shell is equipped with large‑area heat dissipation slots to realize natural convection cooling inside closed control cabinet.
Working Principle AC mains power enters the module through internal wiring terminals. EMI filter circuit removes high‑frequency interference from power grid.
AC‑DC conversion circuit converts alternating current into stable 24VDC direct current.
DC power transmits to DeltaV rack backplane through rear gold‑plated connector and supplies power for controller and I/O modules on each slot.
On‑board sampling circuit continuously monitors output voltage, output current and internal temperature of module.
When overvoltage, undervoltage, overcurrent or overtemperature fault occurs, protection circuit cuts off DC output immediately. The module generates fault flag and uploads alarm message to DeltaV operator station through backplane bus.
Redundant power modules run in parallel. When one module fails, another redundant module takes over full load without power interruption.
Installation Requirements Insert the module along rack guide rail into designated DeltaV rack slot and fully lock mechanical latch.
Connect AC input power cable to module power terminals and tighten terminal screws to specified torque.
Separate AC power wiring from analog signal cables and low‑voltage communication cables to avoid electromagnetic coupling interference.
Reserve sufficient air circulation space around module, do not block heat dissipation slots on module shell.
Complete hardware identification and power threshold parameter configuration in DeltaV engineering workstation after hardware installation.
Precautions for Use Carry out anti‑static protective measures during module handling; bare hands shall not directly touch gold‑plated connector pins.
Cut off AC input power supply before performing wiring modification work.
Verify backplane voltage output after module replacement.
Check terminal screw tightening torque and cable insulation condition in regular cabinet maintenance cycles.
Do not connect AC input voltage exceeding rated range to module power terminals.
Do not disassemble module outer housing; internal high‑voltage power components have no on‑site maintainable spare parts.
