This is a 4A load per channel relay output module capable of up to AC 240V.
If a high switching frequency is needed, using the DC Output Modules is recommended.
After prolonged used, the relay's mechanical contacts may become worn and will need to be replaced. (Individual relays are not available, so the entire module wil need to be replaed.)

On the front of the module, there is a rotary switch used to select the Modbus slave address for the module. When installing multiple modules of the same type, the Modbus slave address for each module should be unique.
Rotary switch position 0 corresponds to Modbus slave address 10. if the ID is changed after the power is applied, be sure to turn the Modport power OFF and then ON again.
