Table 337: C450SPN-4C and C450SQN-4C Expansion Modules with Analog Output Technical Specifications Specification Description Ambient operating conditions Temperature: -40 to 66°C (-40 to 150°F) when using 0 to 10 VDC outputs;-40 to 40°C (-40 to 104°F) when using 4 to 20 mA outputs Humidity: Up to 95% RH noncondensing; maximum dew point 29°C (85°F) Ambient shipping and storage conditions Temperature: -40 to 80°C (-40 to 176°F) Humidity: Up to 95% RH noncondensing; maximum dew point 29°C (85°F) Voltage Mode (0 to 10 VDC): 10 VDC maximum output voltage 10 mA maximum output current Requires an external load of 1,000 ohms or more The AO operates in Voltage Mode when connected to devices with impedance greater than 1,000 ohms. Devices that drop below 1,000 ohms may not operate as intended with Voltage Mode applications. Analog output Current Mode (4 to 20 mA): Requires an external load between 0 to 300 ohms The AO operates in Current Mode when connected to devices with impedances less than 300 ohm. Devices that exceed 300 ohms may not operate as intended with Current Mode applications. Control construction Independently mounted control, surface mounted with Lexan ® 950 enclosure suitable for DIN rail mounting or direct mounting to a hard, even surface.
