JTPLC DDM5A1 Digital Display Table Datasheet
The DDM5A1 digital display table is designed for use with programmable logic controllers (PLC), DCS, computers and other control and acquisition systems to show parameters such as temperature, pressure, flow, speed, angle, position, quantity, frequency, voltage, current, time and fault codes. It supports RS‑485 communication (up to 32 devices) and optional RS‑232 via a converter.
The module features a 5‑digit 0.8" LED display with optional sign, 15 special symbols, 10‑segment bar‑graph display, programmable decimal point, and polarity protection. It operates from a 4.8‑5.5 V DC supply, consumes up to 300 nW, and can be mounted in any orientation. This manual is written in Chinese.
