D4-16NA

About the D4-16NA

The D4-16NA 110VAC Input Module contains 16 inputs. The D4-16NA is a 110VAC input module. The input voltage range is 80-132VAC 47-63 Hz and the input current is 14.5 mA at 120VAC. The module contains 2 commons (isolated) and 8 points per common. The peak voltage is 132VAC. The module contains a removable terminal block. The base power required for 5V is 150 mA maximum. The weight is 9.5 oz. (270 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.
