2 Operating Conditions
Operate the STD35 only with a supply voltage between 7-32V DC and have in mind the polarity! (see
Figure 1) Use a stabilized power supply with minimum 1A output current. (We recommend using only
the original CEP power supply). If you use a mains adapter for power supply it has to conform to the
VDE regulations.
Devices operating at a voltage level > 35V and which are connected to relays must be
installed only by professional technicians according to the local regulatory
requirements for safety!
Loads connected to the device are not allowed to exceed 30 W per relay.
The maximum output voltage is 250 V AC for output 1 and 2 and 30V DC for outputs 3-5
The maximum switching current for output 1 and 2 is 5A and for outputs 3-5 it is 1A
When installing the device make sure that the supply cable has a sufficient diameter
During operation the temperature must be in the range -30° to +75° Celsius.
Protect the PCB (board) of the device from humidity, spray water and heat.
In case of condensation allow a period of about 2 hours for acclimatisation.
Do not operate the device in areas where inflammable gas, vapours, or dust are or could be present.
Do not expose the device to heavy vibrations.
The unit may only be repaired by a specialist.
Only original parts have to be used when repairing the unit. The use of differing spare parts can
cause serious material loss or personal injury.
No special positioning is required to operate the device.
3 Application Areas
The device is designed for the remote switching of devices via the GSM network as well as the remote
retrieval of status information of the inputs and the generation of SMS messages or E-Mails after status
has changed at the inputs. A different utilization of the device other than the ones described here is not
allowed.
4 STD35 Product Overview
The STD35 is a telemetry module which is easy to install and simple to use. It can be configured using
any GSM mobile phone, SMS capable software, or the CEP STD35 configuration tool (sold separately).
With the STD35 you can control five relays and monitor the status of three digital and two analog inputs
with one or several standard mobile phones.
Apart from the STD35 you only need a valid SIM Card from any network provider (GSM850 / 900 / 1800
or 1900 MHz).
Please note: Only use standard [1.8V / 3V] SIM Cards!
