Connections And Leds - Conrad Electronic GX106 Operating Instructions Manual

Connections and LEDs

INPUTS
There are inputs for the operating voltage on one side (no. 1), for two
temperature sensors (no. 2), an analog connection (no. 3) and for both
optocouplers (no. 4). Observe the maximum input voltage of 2V at the
two temperature inputs and the ADC and the maximum input voltage of
12V DC at the optocoupler inputs!
OUTPUTS
There are outputs on the other side to which a red LED is connected for
status display with exception of the PWM. A relay is already connected
to the call output INCALL (no. 5) and the first SMS output SMS1 (no. 6).
Observe the maximum current of the relays (5A/30VDC or 8A/250VAC).
You can directly connect relays to the three other SMS outputs (no. 7)
and the four temperature outputs (no. 8, Conrad order no. 502892). At
the PMW output (no. 9) and with a refresh rate of approx. 1.5kHz, the
maximum voltage of approx. 4V DC can be output with a pulse width of
255 steps.
ANTENNA
The antenna is connected on the circuit board to the left of the TELIT
module. You should first check the receiver quality at the intended
application site with a mobile phone. An adhesive strip is located at the
end of the antenna on the back. Pull off the adhesive strip and attach
the module as far away as possible from the module.
SIM CARD
The SIM card is inserted on the back of the circuit board in the support.
