Simpson Electric M135-0-0-24-0 LCD Digital Panel Meter

This pre-owned Simpson Electric M135-0-0-24-0 LCD Digital Panel Meter is a compact 3-1/2‑digit DC current indicator designed for panel mounting, powered from a 5 VDC supply and reading currents from 0 to 200 mA. It uses a 0.5" high LCD readout for clear visibility and fits a panel cutout of 0.874" x 2.677" with a shallow depth of 0.473" (12 mm). The basic configuration provides a no-backlight display, with an optional negative-image red backlight available on some variants, making it suitable for instrumentation that requires a straightforward current readout without illumination. The M135 series is Simpson Electric’s Mini line of digital panel meters, and the M135-0-0-24-0 variant specifically offers DC current indication in a compact package that can be mounted in electrical panels or instrument enclosures where space is at a premium. This combination delivers a simple, verified DC current readout for monitoring 0–200 mA in a tight footprint, backed by the standard M135 family specifications.
