EM20-FPSI 1010 is a 2 colour voltage level indicator, which can be used as voltage meter or voltage indicator. It provides 0-30V measurement range and meet the demand of various applications.
The EM20-FPSI 1010 is a two‑colour voltage level indicator designed for panel mounting. It compares an input voltage to a programmable window and shows red, green, or red‑green‑red LEDs to indicate whether the voltage is below, within, or above the window. The module operates from a 7 V to 24 V DC supply, offers two user‑programmable thresholds, a control output, low‑power flashing mode, and is housed in a metal bezel with IP67/NEMA 4X protection.
Installation is done via screw terminals with a 20.5 mm cut‑out. The indicator can be configured by storing threshold voltages using a jumper link, and the alarm output goes low when the measured voltage is outside the set range. The datasheet provides full electrical specifications, circuit diagrams, and wiring examples for driving relays, opto‑isolators, and triacs.

It measures input voltages from 0 V to 30 V dc.
The module provides two user‑programmable thresholds.
The alarm output goes low (0 V) when the measured voltage is below V1 or above V2.
The indicator is protected to IP67 / NEMA 4X standards.
