2 Operating Conditions
Operate the STD32 only with a supply voltage between 7-32V DC and have in mind the polarity! (see
picture1) 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
 The maximum switching current for output 1 and 2 is 5A
 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 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 STD32 Product Overview
The STD32 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 STD32 configuration tool (sold separately).
With the STD32 you can control two 5A relays and monitor the status of two digital inputs with one or
several standard mobile phones.
Apart from the STD32 you only need a valid SIM Card from any network provider (GSM850 / 900 / 1800
or 1900 MHz)
While using prepaid SIM-cards, always keep aware of the amount of remaining budget left on the card,
so that in case of alarms a message still can be transmitted.
Please note: Only use standard [1.8V / 3V] SIM Cards!
