4.1.2 Models with Power Relay 220V/6A (5-way plug-in 5.00mm pitch terminal
block)
A 5-way plug-in terminal block connector shared with a 220VAC/6A relay, as shown and described
below, supplies the D.C. power to the modem.
The supply voltage, VCC, required by the modem is in the range of 7 to 50VDC. We recommend a
12VDC power supply. The power supply has to be a single voltage source capable of providing a peak
during an active transmission. The uplink burst causes strong ripples (drop) on the power lines.
By default, the MTX-IoT will automatically switch on when power supply is applied between PIN 2 and
PIN 1.
