rm Ha Controllers and PLC based systems a Al Gas Alarm Systems g li n nd Complete control at the right time and place Every gas detector consist of a gas sensor and a signal transmitter. In case of a gas leak, the signal from the detector has to be processed into an alarm event. There are various options to handle this part of the safety process adequately. It is a question of site policy, design and space, sound recommendation and the customer’s choice. Bionics Instrument • Rack, panel and wall mount alarm units. • Local and centralized alarm systems. • RS-485 output signals for connection to data acquisition and monitoring systems. • Systems which provide maximum exibility towards the future.

PLC Alarm System PLC-system As technology moves on, more sophisticated alarm systems are widely used. When implementing systems with more than twenty five detectors, the use of a PLC-system is worth to consider. Such a compact, software-driven system is simple to expand and allows for quick modifications. User specific functions can easily be programmed. For example functions, which enable the communication with other systems in the facility. Reliable Bionics Instrument uses PLC-systems made by Siemens, which feature the fail-safe redundant configuration with two parallel operating...

Software for PLC Alarm System SIMS-NX Software Sensor Information Management System A PLC-system has lots of advantages. But on its own, it fails to have the possibility of visualisation; it is a ‘blind box’. SIMS-NX is designed to monitor and display the signals of a large variety of sensors on pc screens. That makes SIMS-NX the natural partner for a PLC-configuration. The combination is hard to beat when it comes to flexibility, reliability and functionality. PACT Software PACT is used to program the alarm handling procedures of the PLC-system. An user friendly, well structured, interface...

Single channel controller cards and housings RX-1G Single channel alarm card with a direct indication of the gas concentration. With a 4-20mA input signal and an RS-485 output signal (SIMS). Each card has integrated relay contacts for Alarm1, Alarm2 and Error. When placed in one of the belonging housing the cards can be used to create both small and large alarm systems. Specifications RX-1G Available Housings Model RX-1G Input signal 1x 4-20 mA; inp. impedance 100Ω. 154 15 RX-1G Optional plug in module PC-1192. Output: 4-20 mA (500 Ω Imp.) Output relay contacts Alarm-1: RX-1G RX-1G 4-20 mA,...

Alarm handling explained Alarm controller Alarm handling within the detector A controller is used to convert a signal from a gas detector into an actual alarm. It displays the level of the gas monitored and indicates a possible alarm status with red LEDs. In case of an alarm, a buzzer alerts the operator. Free programmable potential free dry output contacts are available for each alarm level. Next to the conventional centralised set up it is more and more common practice to use systems which have the controller functions integrated inside the detectors. With this type of system event...
