Tagging relays are designed with a serial communications capability that can be used to optimize automated breaker control schemes in new or existing power distribution systems. The relays can also be used to control remote reclosure cutoff and facilitate the expansion of a SCADA system beyond a substation to distribution feeders. They provide a mechanical or mechanical and electrical means for a remote operator to automatically place and remove eye-catching orange warning tags, ensuring personnel safety in compliance with worker-safety tag-out rules. Two-position models offer ‘normal’ and ‘tagged’ positions, while three-position models have ‘closed,’ ‘open’ and ‘tagged’ positions. All models allow bi-directional operation and have two N/O and two N/C contacts per deck. Standard operating voltages are 48 Vdc and 125 Vdc; other operating voltages are available.
