1 ANALOG PWM OUTPUT (PWM)
This is the analog output PWM, whose pulse width can be set via SMS
(with a fixed refresh rate of approx. 1.5kHz). The pulse width can be set
in 255 steps. If the output is to be set to e.g. 50%, you have to send the
text PWM=128.
means that anyone may change the
„Always switch with password"
pulse width who knows and sends the password, or you select the
people in your list at SMS who may switch this output.
2 OPTO COUPLER INPUTS (IN1 - IN2)
These are the two digital optocoupler inputs IN1 and IN2 for e.g. smoke
detectors or burglary detectors (circuits that are interrupted). A voltage
of 0 to 12V can be connected to the input of the optocoupler. Observe
the polarity! The negative pole is connected on the left, the positive pole
on the right.
Without external voltage (meaning open), this input is HIGH. If an exter-
nal voltage is connected, the input becomes LOW and when the circuit
is interrupted, HIGH again. If you now set „Message when input
HIGH" is set for the optocoupler input, and the input becomes HIGH
due to an interruption of the circuit, the module can automatically return
an SMS, a fax or an e-mail with the entered message text. (ALARM
IN1: DIGITAL1). Only an SMS is sent; when the input returns to LOW
and then to HIGH again, another SMS is sent. This also applies anlaog
in the reverse case, if „Message when input LOW" is set.
No output is switched.
1 ANALOG ADC INPUT (ADC)
This is another analog ADC input similar to the T1 and T2 input for the
temperature sensors. In case a set limit value (in mV) is exceeded or
undercut, the module may automatically return an SMS, a FAX or am e-
mail with the entered message text. This input can measure a voltage
of 0V to 2V. If the limit value is to be set to e.g. 1.2 V, you must enter
1200 at limit value.
This is intended e.g. for an analog fill level indicator; the module can
issue a warning message before the storage container runs empty or
