Operating Conditions; Input Function Overview - Conrad GX106 Bedienungsanleitung

6. Operating Conditions

• The GSM module must be operated at direct voltage between 5 - 30 V/DC.
• For operation free of defects, the power source must be able to deliver a current of at least
1000 mA without voltage drop. It is not important whether supply is provided by a
rechargeable battery (e.g. solar rechargeable battery) or a suitable mains adapter with
stabilised output.
• When installing the GSM module, ensure a sufficient cable cross-section of the connection
lines.
• The GSM module should be installed in an area protected from splashing water. It can be
installed in any position.
• Reception for the provider whose SIM card you want to use in the GSM module must be free
of interferences at the mounting site of the GSM module or the GSM aerial; its field strength
must be as high as possible.

7. Input Function Overview

This GSM module has 5 inputs. Every input can send an SMS, fax or email as information upon
a previously defined input signal. The following inputs are available:
• Two digital inputs "IN1" and "IN2" that recognise and indicate pre-defined digital switching
conditions (high or low) at input voltages between 0 - 12 V/DC. These inputs are used, e.g.
for smoke detectors, burglary alarms (current loops that are interrupted) or outputs of an
alarm system.
• An analogue input ("ADC") can record and indicate measurement results. The input
measurement range is 0 - 2 V/DC. If this voltage range is not sufficient for your applications,
voltage separators can be used for corresponding adjustment. For this, observe the
additional notes in chapter "Analogue Input (ADC)" in these operating instructions. The
analogue input is used, e.g. for fill level indicators (with slowly changing analogue voltages
of 0 to 2 V).
• Two temperature inputs "T1" and "T2" are used for temperature measurement and control.
One temperature sensor each (e.g. Conrad item no. 198896) can be connected to the two
temperature inputs. These inputs are used, e.g. to monitor room temperatures and for
targeted control of heating systems.
