Electroswitch闭锁继电器Series 24 Lock-Out Relay产品介绍：
The Electroswitch Series 24 Lock-Out Relay, the Utility Industry Standard for Quality and Reliability, is now available with:
• Integral Coil Monitoring with LED Display and SCADA Feedback.
• LED Indication of Existing Fault Signal.
The Lock-Out Relay fills one of the most critical needs in the utility industry protection scheme.
A fast, reliable Lock-Out Relay can mean the difference between a routine fault clearance and a
disastrous loss of service, maintenance time and expensive equipment damage.
To assure that this crucial device is functioning and ready to operate, many utilities install pilot
lamps on the panel to monitor the integrity of the LOR coil. This can involve expensive interwiring
and use precious panel space. Because of this, Electroswitch has integrated these monitoring
functions and more on a new electronic nameplate for the LOR.

• Saves Panel Space.
• Reduces Purchase and Installation Cost.
• Easy to Use…No Special Operator Training.
How it Works
When the LOR is in the RESET position, one high visibility LED on the nameplate glows a continuous
GREEN, giving local indication that coil continuity is intact and the Lock-Out Relay is ready
to respond to a trip signal. Should the coil fail, the LED extinguishes and a built-in solid state
contact closes, sending a warning signal to SCADA.
In the TRIP position, the red LED functions as a Trip Signal Monitor. As long as the Trip Signal is
present on the LOR coil, the LED glows a continuous RED as a warning against resetting into a
fault and possibly damaging the LOR coil. Other LED colors available (Amber, Blue and White).
The new design also retains the proven mechanical orange/black flag to indicate a trip.

can put the Electroswitch tradition of value and innovation to work for you.
Ordering Information
Part Numbers for the Series 24 LORs with Lighted Target Nameplate are fairly simple. Find the part number
of the product you wish to order in the Electroswitch catalog, then simply add a two letter code after the second
digit in its part number. The first letter of the two letter code will always be “ P “ indicating a Lighted
Target Nameplate. The second letter of the code will change depending on the other options as follows.
A = One LED, 48/125VDC B = Two LEDs, 48/125VDC K = Two LEDs, 24VDC
Please Specify LED Colors. Color Options - Red, Green, Amber, Blue and White.
A Series 24 Manual Reset Lock-Out Relay with one deck and Trip Coil 'D' is part number 7801D. The same
Lock-Out Relay with a Lighted Target Nameplate, Two LEDs, and 48/125VDC LED voltage would become part
number 78PB01D.
