Page 7: Product Description
Principle of operation Application area The VEGATOR 121 is a single channel controller for level detection of limit switches with 8/16 mA interface. Via the integrated relay simple control tasks can be solved. Typical applications are monitoring func- tions such as overfill or dry run protection, Optionally an additional second relay can be ordered. -

Page 9: Mounting
Mounting General instructions Mounting options VEGATOR 121 is designed for carrier rail mounting (top hat rail 35 x 7.5 according to DIN EN 50022/60715). Due to its protection rating of IP20, the instrument is suitable for mounting in switching cabinets. It can be mounted horizontally and vertically. -
Page 10: Connecting To Power Supply
Voltage supply The data for power supply are specified in chapter " Technical data". Connection cable The voltage supply of VEGATOR 121 is connected with standard cable according to the national installation standards. The sensors are connected with standard two-wire cable without shielding. If electromagnetic interference is expected which is above the test values of EN 61326 for industrial areas, shielded cable should be used. -
