Product Overview

DL230 is loop‑powered digital process indicator. It draws operating power directly from 4‑20 mA instrument loop, displays scaled engineering value and provides two‑point relay alarm output for high/low process‑value interlock. Ideal for local on‑site value read‑out for pressure, flow, temperature transmitters. Surplus and refurbished tested spare loop‑indicator unit for process‑plant instrument‑system maintenance projects.

Application Notes

‑ Configure engineering range and alarm set‑points via front‑panel push‑buttons. ‑ Ensure sufficient loop driving current for indicator operation. ‑ Typical deployment: Loop‑powered process‑indicator spare‑part stocking.
