The ABB REF601 is a dedicated feeder protection and control relay belonging to the Relion 605 Series. Designed for primary and secondary distribution networks, the REF601 provides protection, monitoring, and control functionality for utility and industrial power system overhead lines, cable feeders, and distribution transformers. It features an integrated local human-machine interface (LHMI) with built-in control buttons for single circuit breaker operation, support for conventional CTs or Rogowski current sensors, and serial communication capabilities.

Replacing a 1756-L73 does not automatically mean upgrading its firmware. This guide compares v19.013, v21.011 and v31.011, focusing on project compatibility, HMI communications, legacy networks and...
Implement a 3-SPST switch XOR light circuit in LogixPro or RSLogix 500 using an internal relay bit. Includes truth tables, boolean equations, and verified.
Integrate Allen-Bradley CompactLogix, Caterpillar ATS, and generators into DeltaV DCS over Modbus RTU. Covers ProSoft MVI69-MCM, Miille DIN266 gateways.
ONS instruction fires but the OTE coil never latches in Studio 5000 because the one-shot is only true for one scan. Use OTL/OTU or seal-in logic instead.
Configure Allen-Bradley Kinetix 5500 servo drives on EtherNet/IP. Covers CIP Sync, IEEE 1588 V2 timing, Stratix selection, DLR topology, and HMI.
A moving-average filter is the sliding-window smoother most instrument engineers drop into DCS and PLC analog paths. Here is how the window works, how N and sample time set lag, and when a...
