Voltage Sensor LG2 CSM LG2 DS E 4 2 Compact, Economical Plug-in Type Voltage Sensing Relay DPDT output contacts expand the application of the Sensor to wide-ranging fields including control, alarms, and indication. Voltage control is possible in the same easy manner as electro- magnetic relays, as the output relay of the sensor can be driven directly with a detection signal. Wide voltage setting range with fine setting capability. Model Number Structure Model Number Legend LG2- 132 1. Voltage sensor 2, 3.
