Applications
- Digital signal acquisition: The 8 digital inputs acquire 24 V DC Sink/Source signals.
- Relay output control: The 8 relay outputs control loads through rated AC and DC output voltages, with switching capacity up to 2 A.
Key Features
- Digital I/O configuration: 8 digital inputs and 8 relay outputs, with inputs in groups of 2 and outputs in groups of 2.
- 24 V DC inputs: Input rated value is 24 V DC; signal 0 is 5 V DC at 1 mA and signal 1 is 15 V DC at 2.5 mA.
- Relay output switching: Relay outputs support 5 V DC to 30 V DC and 5 V AC to 250 V AC, with a maximum switching capacity of 2 A for resistive loads.
- Diagnostics and protection: The module has diagnostic alarms and LED indications for input and output status. Short-circuit protection is not provided and must be provided externally.
- Installation and isolation: IP20 protection is provided. Digital outputs have relay isolation between channels, and isolation from the backplane bus is 1 500 V AC for 1 minute.
