The Bus Controller MOD BUS Creator is designed to structuring (chopping) an entire system into small portions with an isolated local data bus in each portion. Such local sections of the data transmission bus can operate, depending on the device option, according to the RS-485 standard interface (PW-120-485 unit) or Teta interface (PW-120-T unit -  Atest Gaz standard).

EcoAlpa is a two-channel control unit designed to work with gas detectors with a 4 - 20 mA interface - it is responsible for visualizing the operation of the entire Gas Safety System and for developing appropriate output signals.

The EcoAlpa5 Control Unit enables visualization of the entire Gas Safety System and provides appropriate output signals for the system control.

The Alpa MOD LED8 Control Unit Module is a device designed to reads the signals in 4 – 20 mA standard, reads signals exceeding the warning alarm thresholds, indicates gas detectors damage (e. g., breaking a wire) and works with optical – acoustic signaller.

The Control Unit Module Alpa MOD LED1 is a single-channel control device designed for operation at
facilities with a risk of hazardous gases presence.

MOD CNV PK420 enables extension of an existing Gas Safety System and is meant to convert an On/Off signals received from relay outputs of the Control Unit into a discrete signal 4..20 mA.

Industrial systems widely use communication systems based on the RS-485 transmission standard. The serial nature of the RS-485 bus networks is the reason that a critical failure at any location of the network may disable communication within the entire system. Since Gas Safety Systems are very sensitive to perfect efficiency of communication, even potential, critical or probable failures of data bus lines may be really hazardous to safe operation of the system. It is why application of devices capable of isolating any defective fragment of the network, such as MOD SEP 2 modules, is beneficial and efficient.

The Control Unit Module Sigma  MOD DO is designed to present the status of relay outputs.

The Control Unit Module Sigma MOD LCD is a component of the Gas Safety System Sigma Gas. The module’s functions include i.a.: communication with gas detectors, control of visual and sound indicators and display of system status to the operator. This device is designed to work with Sigma MOD LED.

The Control Unit Module Sigma MOD LED is a component of the Gas Safety System Sigma Gas. The module’s functions include i.a.: communication with gas detectors, control of visual and sound indicators and display of system status to the operator. Cooperate with Control Unit Module Sigma MOD DRV and Sigma MOD LCD it is possible to create a system dedicated for several alarm zones with a configuration dedicated to the customer's needs.
