This document is the user manual for DAM-3000 Data Acquisition Modules, which includes terminal distribution diagram, main indicators, input/output modules, power supply and power consumption, wiring diagram, structure diagram, and code configuration table.
The DAM-3026D module provides 8 isolated digital inputs and 3 relay outputs. Input high level ranges from +4 V to +30 V, low level from 0 V to +1 V, and the relay contacts are rated at 240 VAC @ 1 A with a 6 ms closing time and 3 ms release time. Isolation voltage is 3750 V and the module supports a dual watchdog.
Power is supplied from an unregulated +10 V to +30 V DC source, with a consumption of 1.3 W at 24 V DC. LEDs indicate input and output status. Configuration is performed via UART with selectable baud rates from 1200 to 115200 bps, as listed in the baud‑rate table. This manual is written in Chinese.
