1. DESCRIPTION
MCF-LW06424B is a class A LoRaWAN interface, ables to read 4 analog inputs 4-20mA with a resolution of
12 bit. Inputs have an insulation of 1000Vdc with respect to the power supply, and are protected against
polarity inversion. It has a protected digital output to drive a load 24Vac/dc up to 500mA, useful for power
the connected sensors only when making the measurement, and save energy.
MCF-LW06424B is available with an optional DIN rail mount board (MCF-DIN105) as follow:

3. LORAWAN™ ACTIVATION
The device supports the following activations on a LoRaWAN ™ network:
NONE: sensor not activated
OTAA: needs settings of appkey and appEUI
OTAA MCF88: Over the air activation according to enginko specifications
ABP: needs settings of NwkSkey, AppSkey, DevAddr
The device exits factory activated with NONE mode. The devEUI of the device is shown on the product
label. MCF-LW06424B is a Class A LoRaWAN ™ device.

5. INSTALLATION
The magnetic antenna must be positioned on a metal body. It should preferably be vertical and at least 30
cm away from other metal bodies.
The installation must take place in a place where the LoRaWAN ™ signal coverage is good (SF=7 optimal,
SF=12 weak).
