ABB FER615E-D Replacement for 615 Series Relion IED

Product Overview

ABB FER615E-D Replacement for 615 Series Relion IED: Seamless Migration & Compatibility Upgrade

When your existing feeder and motor protection relay reaches end-of-life or becomes obsolete within your substation or industrial control panel, the ABB FER615E-D offers a proven, drop-in-compatible upgrade path within the ABB 615 Series Relion platform. Designed for engineers and procurement teams managing legacy protection schemes, this IED (Intelligent Electronic Device) is engineered to minimize engineering rework, reduce panel downtime, and preserve your existing wiring infrastructure wherever possible.

The FER615E-D is a dual-function feeder and motor protection IED that consolidates overcurrent, earth fault, thermal overload, and motor start supervision into a single compact unit. For facilities currently operating older ABB SPAJ 140 C, SPAM 150 C, or SPAS 114 C relay generations, the FER615E-D represents a direct functional upgrade with modern IEC 61850 GOOSE messaging and IEC 60870-5-103 protocol support — eliminating the need for costly protocol converters or gateway hardware in most retrofit scenarios.

A successful migration from legacy protection relays to the FER615E-D typically involves more than a one-for-one relay swap. In practice, field engineers will also evaluate the surrounding system components to ensure full compatibility across the protection chain.

For sites using older SPA Bus or LON-based communication backbones, the transition to IEC 61850 GOOSE messaging may require updating the substation automation gateway — commonly an ABB COM600 series station automation unit or an equivalent RTU. The FER615E-D integrates natively with COM600 without additional protocol mapping, significantly reducing commissioning time.

On the I/O side, engineers migrating from REF 541 or REF 543 platforms often find that the FER615E-D’s onboard binary I/O count is sufficient for standard feeder applications, but motor protection schemes with extensive interlocking may benefit from adding an REX 610 I/O extension module to the same panel section. This preserves the existing wiring scheme while expanding the relay’s digital input and output capacity.

Power supply compatibility is a common concern during retrofit projects. The FER615E-D’s wide-range auxiliary supply (24–250 VDC / 100–240 VAC) means it can operate directly from existing 110 VDC or 220 VDC station batteries without requiring a dedicated DC/DC converter — a significant advantage over some earlier Relion generations that required fixed-voltage supplies. If the panel also houses an ABB REC670 or REL670 bay controller, the shared DC bus arrangement remains fully compatible.

For programming and configuration, the FER615E-D is managed through ABB’s PCM600 software, replacing the older CAP 505 or CAP 531 toolchain. Engineers familiar with the legacy tools will find the migration straightforward, particularly for standard overcurrent and earth fault schemes. The PCM600 application library includes pre-built function blocks for feeder and motor protection that map directly to the FER615E-D’s hardware, reducing configuration time on site.

Wiring adaptation is often the most time-sensitive aspect of a relay replacement. The FER615E-D uses the standard 615 Series rear terminal layout, which is compatible with the existing panel cutout dimensions used by the REF 615 and REM 615 families. For panels originally wired to SPAJ or SPAM series relays, a terminal adapter plate is recommended to bridge the legacy wiring harness to the 615 Series connector pattern — this eliminates the need to re-terminate individual CT, VT, and binary I/O cables at the panel rear.

Sites that include ABB ACS880 or ACS580 variable frequency drives in the same motor control center will find that the FER615E-D’s motor start supervision and thermal overload functions integrate cleanly with the drive’s fault output signals via standard binary inputs, maintaining the existing interlock logic without PLC reprogramming.

Retrofit Guidance FAQ

Q: Can the FER615E-D reuse existing CT and VT wiring from a SPAJ 140 C installation?
A: In most cases, yes. The FER615E-D accepts 1A or 5A CT inputs (selectable) and standard VT secondary voltages. A wiring audit is recommended to confirm terminal mapping before energizing. A terminal adapter plate may be required for legacy connector formats.

Q: Is the IEC 61850 configuration compatible with our existing substation automation system?
A: The FER615E-D supports IEC 61850 Ed.2 and is compatible with most modern substation automation platforms including ABB COM600, MicroSCADA Pro, and third-party IEC 61850 clients. For legacy SPA Bus or LON systems, a protocol gateway will be required.

Q: How much panel space does the FER615E-D require compared to the relay it replaces?
A: The FER615E-D occupies a standard 4U flush-panel cutout consistent with the 615 Series form factor. For panels originally housing 6U or larger legacy relays, the remaining space can be used for terminal blocks or I/O extension modules.

Q: Do we need to reprogram our PLC or DCS after installing the FER615E-D?
A: Typically no, provided the binary I/O signal mapping is preserved. The FER615E-D’s configurable output relay assignments allow engineers to replicate the existing trip, alarm, and indication signal scheme without changes to the upstream PLC or DCS logic.

Q: What engineering software is required for commissioning?
A: ABB PCM600 (Protection and Control IED Manager) is required for full configuration and testing. A standard PC with a USB or Ethernet connection to the relay front port is sufficient for on-site commissioning.
