The Lascar EM20-FPSI1010 is a 2-color voltage level indicator which is designed to be easily panel mounted in most applications. The module compares an input voltage to a defined voltage window. The color of the display shows whether the input voltage is below, within or above this window. The indicator provides a red-green-red bright LED indication over 0 to 30V measurement range. The module operates from a 7 to 24Vd.c. supply. The user can easily set the color switching thresholds. Hysteresis is built-in to avoid chattering at the colour switching thresholds. The module incorporates 1 alarm output, allowing the user to drive an external alarm or control a process being monitored. A low power mode is also available, whereby the module indicates the voltage level by flashing the relevant color, instead of indicating solid colors. Connection is via screw terminals. The module features a round metal bezel,requiring a 20.5mm (0.81") diameter cut-out. It is secured with the nut provided. Protection from the front to IP 67 / NEMA 4X standards is achieved by placing the compressible silicone seal between the module and panel during assembly. The rear of the module is potted to prevent ingress of water. (5F)
