Features

The EM20-FPSI 1010 is a ready-to-use panel mounted SMART indicator. This compact LED module indicates green when the input voltage is between two easily programmable levels and red when the input voltage is higher or lower. The levels are easily set and stored in Flash memory. They can be changed as often as desired. This unit can be used in countless applications where a GO / NO GO indicator is required. The module incorporates one output, allowing the user to drive an external alarm or to control the process being monitored. The module uses a metal bezel providing IP67/NEMA 4X protection and screw terminal connectors for easy installation. A 20.5mm (0.81?) diameter panel cut-out is required to mount the unit.
