The ADS-DM318 multi-channel signal acquisition digital control module has 1 to 8 optional channels, which can be selected from AO (analog output), DO (switch output), or DI (switch input). The total number of channels for AO, DO, and DI cannot exceed 8.
This module achieves isolation between various channels, with each channel isolated from communication and module power supply.
The module uses RS485 communication protocol and Modbus RTU protocol (slave mode).

The IO module only has a maximum of 8 channels, so the total number of channels for relay output, switch input, and analog output cannot exceed 8 channels. For example: Example 1: When 8 analog outputs are selected and the analog output type is 4-20mA, the model is ADS-DM318-0T0K8A1. Example 2: Select 4 relay outputs and 4 analog outputs. If the analog output type is 4-20mA, the model is ADS-DM318-4T0K4A1. Example 3: Select 2-point relay output, 2-point switch input, and 4-way analog output. If the analog output type is 0-5V, the model is ADS-DM318-2T2K4A2. |
