INSTALLATION AND BUILDING AUTOMATION FROM ZAMEL
UNIVERSAL MODULES FOR CONTROLLING LIGHTING, HVAC COMPONENTS, AND OTHERS.
Automation has long ceased to be limited to industry – today it extends much further, reaching offices, apartment buildings, and single-family homes. Zamel modules make it possible to automate many installation elements at a relatively low cost: outdoor and indoor lighting, heating systems, and more.
Below, we present an overview of the Zamel range in the field of installation automation. Most of the modules presented here are designed for DIN rail( TH35) mounting and can perform a variety of functions – although the offer also includes products intended for specific applications( e. g. lighting controllers). The presented solutions can be purchased directly from the TME catalog.
This article covers the following topics:
• Relays used for load control
• Applications and capabilities of time relays
• Electrical and environmental protection devices
• Monitoring energy consumption and quality
• Key building automation control elements
• Sensors used in architectural automation
Installation Automation
First, it is worth focusing on universal components that can be used for a variety of purposes in diverse applications, both in homes and in industry.
Relays and Contactors
Zamel relays are available in bistable, impulse, monostable, and priority versions, meaning they can be controlled by pushbuttons, switches, pulses from monitoring devices, and other signals commonly used in electrical installations. They support maximum currents ranging from 5A to 100A. In most cases, the control voltage is 24V AC / DC or 230V AC, while the rated coil voltage ranges from 12V to 230V. Some models incorporate a relay state memory system, ensuring automatic restoration of the state prior to a power failure.
PBM-01 Installation Relays STM-25-40 Contactors SPM-05-11 Auxiliary Contacts
The supplier’ s contactors offer similar parameters. They support currents of 25 … 100A and are available in 2-, 3-, and 4-pole configurations( mostly NO contacts). Complementary products include auxiliary contacts – slim-profile modules that extend the functionality of Zamel contactors to additional circuits.
Time Relays
Zamel time relays are available in digital and analog versions. Digital models offer extensive functionality, with up to 25 independent operating modes( delays, hold functions, cyclic operation, or bistable counting ranges from 0.1s to 100h, and even up to 1 year). The modules feature a configuration interface( buttons and LCD display) located on the front panel, simplifying installation and adjustment. Alternatively, for example in the case of the ZCM-42 model, programming can be carried out remotely via WiFi.
ZCM-11 Digital PCM-10 Analog
A more economical alternative to digital models is analog time relays. These also offer multiple operating modes and support long timing periods( from 0.1s to 100 days). This product group also includes flushmounted versions, enabling functions such as timed lighting control( e. g. in corridors or stairwells) without requiring additional modules in the distribution board.
Monitoring Relays
Monitoring relays are devices used in automation and electrical installations for continuous monitoring of selected operating parameters. Their purpose is to detect abnormalities and trigger an appropriate response, such as activating an alarm, switching on equipment, or disconnecting the power supply. Zamel offers several types of such protection devices:
PNM-31 Voltage Monitoring Relays PZM-10 Liquid Level Monitoring Relays PRM-10 Temperature Monitoring Relay RTM-02 Temperature Controllers
The product range includes relays that monitor electrical network parameters( voltage), liquid levels in tanks( boilers, reservoirs), and temperature.
It is also worth mentioning that for more advanced control applications related to thermal conditions, Zamel manufactures precise and multifunctional temperature controllers, where the device can be used
