The base power required for the F4-08NE3S AC/DC Input Module at 5V is 90 mA maximum. The weight is 9 oz. (256 g). The operating temperature is 32° F to 140° F (0° C to 60° C). The operating humidity is 5% to 95% relative humidity (non-condensing).
Each point on the module has a logic side indicator.The On or Off status of the indicator reflects the status of the point with respect to the CPU. If the indicator LED is On, the input circuitry is operating properly. Verify the LED goes off when the input signal is removed. If you suspect that the module has failed, replace it, if you have a spare. This is an effective method of troubleshooting. If you suspect another device to have caused the failure in the module, that device might cause the same failure in the replacement module as well.
The F4-08NE3S AC/DC Input Module contains 8 (sink/source) inputs. The input voltage is 90-150 VAC/VDC The module contains 8 commons (isolated) and 1 point per common. The peak voltage is 350 peak < 1ms. The module contains a removable terminal block.
