This is a 4A load per port 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 will need to be replaced).
General Digital I/O (DIO) modules can be installed in the 6 slots directly to the right of the CPU module in the slots labeled “DIO”. The slot in which the DIO module is installed determines its I/O port number.
When a general DIO module is installed in position “+0” its ports will be assigned numbers 0 through 7. When installed in position “+30” its ports will be assigned numbers 30 through 37.
