Performance Curves

Derating Curves:

Embedded Digital Inputs (No Cartridge): Shows the relationship between ambient temperature and the input simultaneous ON ratio. At 45°C (113°F), 100% ON ratio is supported. This decreases to 80% at 55°C (131°F).

Embedded Digital Inputs (with Cartridge): Similar to the above, but with a cartridge installed. 100% ON ratio is supported up to 45°C (113°F), decreasing to 50% at 55°C (131°F).

Embedded Digital Outputs (No Cartridge): Illustrates the derating for digital outputs. 100% ON ratio is supported up to 45°C (113°F), decreasing to 80% at 55°C (131°F).

Embedded Digital Outputs (with Cartridge): Shows the derating for digital outputs with a cartridge. 100% ON ratio is supported up to 45°C (113°F), decreasing to 50% at 55°C (131°F).
