GE-IC698PSA100 PACSystems RX7i 100W Rack Power‑Supply Module

Description

Core performance features

‑ Input range: auto‑ranging 85‑264 VAC (47‑63 Hz); also accepts 100‑150 VDC DC power source, supports dual‑type field power access. ‑ Rated output power: total 100 W output power. Output rails: +5 VDC @ max 20 A; +12 VDC @ max 2 A; ‑12 VDC @ max 1 A. ‑ Cooling mode: natural convection cooling, no fan required for 0‑60 ℃ full‑range operation, reducing fan‑related failure riskKongJiang …. ‑ Power‑hold‑up performance: minimum 15 ms line‑ride‑through capability, short‑term input power fluctuation will not trigger rack power‑down fault. ‑ Built‑in multi‑layer protection: over‑voltage protection, over‑current protection, over‑temperature shutdown protection. Front‑panel LED indicators reflect input status, output health and overtemperature alarm status. ‑ Front‑panel logic on/off switch: can disable back‑plane DC output without cutting off field AC/DC input power, convenient for on‑site module hot‑swap maintenance work. ‑ Mechanical rule: strictly occupies slot 0 of RX7i rack, cannot be placed in ordinary VME working slots. Supports hot‑swap under redundant system architecture. ‑ Environmental parameters: operating temperature 0‑60 ℃; storage temperature‑40 ~ +85 ℃; humidity 5‑95 % non‑condensing; IP20 protection grade, cabinet‑internal installation only. ‑ Compatibility note: matches all RX7i series CPU and VME modules, including CPE, CRE redundant CPU and ETM communication boards. When adding many high‑power VME boards, calculate total back‑plane power consumption; if total load exceeds 100 W, upgrade to high‑power IC698PSA350 power supply instead.

Physical appearance

Standard 6U VME plug‑in power‑supply unit, fits RX7i rack slot 0 position. ‑ Front metal faceplate: power status LED indicators, logic on‑off toggle switch; power input terminal block for field AC/DC wiring; model label printed IC698PSA100. Equipped with metal ejector latches for inserting and extracting. ‑ Rear side: large‑size VME golden‑finger contacts, transmits multi‑rail DC power and power‑sequencing signals to chassis back‑plane. ‑ Internal passive convection cooling structure, ventilation holes distributed on upper and lower housing surfaces for heat dissipation. ‑ All field power wiring terminates on front‑panel terminals; no process signal wiring terminals.

On‑site application scenarios

Installed on the far‑left slot of RX7i control rack inside power‑plant and petrochemical cabinets. It provides stable multi‑voltage power for the whole VME back‑plane, supporting CPU, communication boards and various VME‑format I/O modules to run normally. If this power‑supply module fails, the whole RX7i rack will lose back‑plane power, all controllers and I/O boards stop working, which may trigger unit safety interlock actions. After replacement, check field input voltage value and wiring tightness, observe front‑panel LED status, measure each back‑plane DC output rail voltage, verify whole rack modules can be normally identified before putting online.

Installation & operating notes

‑ Even though hot‑swap is supported under redundant configuration, power‑off replacement is strongly recommended in most field‑site maintenance to avoid scratch and oxidation damage to VME golden‑finger contacts. ‑ Field power input wiring shall adopt suitable‑gauge wire, keep proper distance from high‑power heavy‑current cables to reduce conducted interference. Ensure cabinet grounding is reliable. ‑ Keep ventilation holes of power‑supply module unblocked. Do not stack cables or components around ventilation slots; poor heat dissipation will trigger overtemperature protection and shorten service life. ‑ Calculate total power consumption of all VME modules before adding new boards, avoid over‑loading IC698PSA100 100 W power rating. ‑ Do not open metal housing for component‑level repairing. Replace whole power‑supply unit for permanent hardware damage.

Common field phenomena & troubleshooting

1. All front‑panel status indicators stay dark: Check field AC/DC input power and terminal block locking; confirm front‑panel logic switch is at ON position; re‑seat module firmly in slot.
2. Overtemperature alarm LED lights up: Check cabinet ambient temperature, confirm ventilation holes are not blocked, eliminate surrounding heat‑source influence.
3. Rack partial modules cannot start normally: Measure each DC output rail voltage; judge whether total back‑plane load exceeds 100 W rated output power.
4. System random power‑down and restart: Inspect field input power quality, check for large‑load equipment surge interference; verify power‑supply terminal wiring is not loose.
5. Hot‑swap causes whole rack power‑off: Confirm system is full redundant configuration; check VME golden‑finger contacts for dust and oxidation contamination.
