| Product Name: |
96 x 96 mm limit controller |
| Description: |
The limit control LIMITROL L41 is an over temperature or a high limit safety device with a latching output that could remove the power while the process is in abnormal condition, for example the process higher than high limit set point or lower than the low limit set point.
