The SUNSTAR SSD600A is a digital temperature and humidity controller with watchdog circuit, power‑loss protection, four‑window LED display and relay alarm…
The SSD600A temperature‑humidity controller is designed for precise measurement and control in a wide range of industrial applications. It features a three‑row 4‑digit LED display that shows humidity, temperature and set‑point values simultaneously, and offers selectable input voltage ranges, watchdog protection, software traps, redundancy and digital filtering for high reliability.
The instrument can be powered from 220 V AC ±10 % or 24 V DC or 12 V DC, accepts standard voltage inputs (0‑5 V or 0‑10 V), and provides alarm relay output (AC 250 V/3 A) as well as a 12 V DC power‑out port. Various models and sizes are available, with dimensions from 48 mm to 160 mm and optional RS‑485/RS‑232 communication or printing interfaces. This manual is written in Chinese.
