Hi,
Recently a NCD.io Contact Closure Push Notification for MQTT over WiFi module was put upon my desk with a note to make it work. No manuals, no cables, no power supply.
The sticker on the rear of the device states the input voltage to be 4 - 12 Vdc, but it seems to need at least 6Vdc to power up properly.
I visited the NCD website, and the relevant pages provided me with an additional 2 sets of voltage input figures:
- “Externally Powered Using a 6-32VDC Power Supply” ( https://store.ncd.io/product/contact-closure-push-notification-for-mqtt-over-wifi/ )
- “Input voltage range: 5-24VDC(12VDC nominal)” ( WiFi MQTT Push Notification Sensor User Guide - NCD.io )
So my question to you is which set of figures for the input voltage range is correct?
For our application a 24Vdc rail already exists, so being able to run off 24Vdc would be optimal.
(my fingers are crossed that you say that the 6-32VDC input figure is correct)
Thanks.
