Description
‑ Power Supply：AC input 120‑240VAC auto‑ranging, DC compatible input 125VDC; active power factor correction PF＞0.95
‑ Mechanical Structure：Plug‑in power module for Symphony power rack；overall weight approx 2.10kg
‑ On‑board Resources：AC‑DC conversion circuit, current‑sharing parallel control circuit, output over‑voltage / over‑current / over‑temperature protection circuit, power monitoring and fault reporting circuit.
‑ Communication Interface：Internal power back‑plane bus, realize current‑sharing and fault signal reporting to power monitor module.
‑ Galvanic Isolation：Galvanic isolation between input AC side and field DC output side.
‑ Core Function：AC‑DC power conversion, output stable 25.5VDC field power for I/O modules, multi‑module parallel current‑sharing, over‑voltage / over‑current / over‑temperature protection, power fault signal upload.
‑ Protection：Over‑voltage protection, over‑current limiting, over‑temperature shutdown, input surge protection.

‑ Weight：approx 2.10kg
‑ IPFLD24 outputs rated 25.5VDC, total output power 286W, provides field excitation power for rack I/O termination units and I/O slave modules. It is strictly distinguished from IPSYS01 system power module, IPSYS01 is for processor, communication card and back‑plane logic power, IPFLD24 is only for field I/O power supply。
‑ Support multiple modules parallel current‑sharing, realize N+1 or 2N hot‑redundant configuration. When one power module fails, remaining modules automatically share full load without power interruption for field I/O loop.
‑ Built‑in complete protection mechanism: output over‑voltage lockout, over‑current current‑limiting, over‑temperature automatic shutdown. Fault status can be reported to DCS through power monitoring module.
‑ Installed on Symphony dedicated power rack, cannot work independently, must match IPSYS01 system power module and power monitoring unit.
Difference compared with IPFLD01：IPFLD01 is 143W low‑power field power; IPFLD24 is 286W high‑power upgraded version, double output capacity for large‑quantity I/O racks。
‑ Complete AC‑DC conversion, stable 25.5VDC field power output for I/O hardware.
‑ Monitor module internal temperature, output voltage, output current, report power failure alarm signal.
‑ No process control logic function, only undertake power conversion task.
‑ Back‑plane：Power rack internal power back‑plane, realize power output, parallel current‑sharing and fault signal transmission.
‑ External interfaces：AC power input terminal.
‑ Mounting：Plug‑in installation on Symphony dedicated power rack
‑ Operating Temperature：‑20 ℃ ~ +60 ℃
‑ Storage Temperature：‑40 ℃ ~ +85 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Pollution degree：Degree 2
‑ Protection Class：IP20, cabinet‑internal installation.

Complementary parts: Symphony power rack, IPSYS01 system power module, power monitor unit, Harmony I/O modules and terminal units, AC input breaker.
‑ Insert module into power rack dedicated slot, tighten front‑panel locking handle to guarantee reliable back‑plane contact.
‑ For redundant parallel configuration, strictly follow installation manual for current‑sharing setting; load calculation shall reserve sufficient margin.
‑ Module replacement recommends power‑off operation. After replacement, verify power‑good indicator light, measure 25.5VDC output voltage, confirm I/O field power supply normal.
‑ Do not mix‑use IPFLD24 and IPFLD01 in parallel, power mismatch will cause current‑sharing abnormality.
