next one: 
Last one: OMRON K3NR-NB2A
Control power supply voltage: 48 VDC.
Input: DC, Input voltage range, 0.2 to 12 V.
Overvoltage/Undervoltage Monitoring.
Relay for AC and DC Input.
Detect overvoltages or undervoltages (switch select,
able) from 4 mV to 300 V.
Detect undercurrent, reverse current, or overcurrent in,
DC circuits using shunt (SDV-FL) .
Detect three-phase AC current for under and/or overcur,
rent using current converter K3NR-NB2A
Available in 7 supply voltage configurations.
Single-function model with ON-delay, OFF-delay, or star,
tup lock settings (SDV-FH@T).
Select either AC or DC voltage input.
Polarity can be specified (SDV-FL) to enable easy re,
verse current detection.
Selectable reset value range from 2% to 30% of operat,
ing value (SDV-F) K3NR-NB2A.
LED operation indicator.
UL/CSA approval (SDV-F@). Shape: rectangle.
Protection structure: IP40.
Action: alternate.
Operation Department color: red.
Column length 18mm, circular F8 series.
High brightness and with uniform light.
Round type easy opening.
Small and operation feel good. Mounting method: Embedded with no screw threads K3NR-NB2A.

Water- and Environment-resistive FA.
Connectors Save Wiring and Maintenance Effort.
Compact FA connectors meet IP67 requirements and ensure a,
94V-0 fire retardant rating.
A wide array of connectors makes a wiring system more modular,
simplifies maintenance, and reduces downtime.
Connectors with Cables and Connector Assemblies are available.
Three types of Connector Assembly: Crimping, soldering, and screw-on.
Connectors with Cables are UL certified.
