Statox 503 SIL 2 module contrôle
Compur Statox 503 Control – and Common Alarm Module
The All – Rounder in Gas Detection
No matter if you want to detect toxic or combustible gases: This control module works with any sensor head. It provides the power supply and processes the signal. Three relays rated 8 A and a 4 – 20 mA output interface with peripheral instrumentation.
Potential front ends may be the Statox 501 or Statox 505 transmitters with electrochemical or infrared sensors, or sensor heads with a Wheatstone bridge signal such as Statox 501 PID, catalytic sensors or the Statox 501 LC and MC series with infrared sensors. Just by the push of a button you can program the module to handle 4 – 20 mA sink or source. Even the bridge voltage can be set to any value between 2 and 5.2 V, i.e. it would even work with sensor heads of other manufacturers. So there is no restriction at all when selecting the appropriate sensor head for your application. With its two “sense” lines it can even compensate the voltage drop in the cable for very remote sensor heads, or if there are extreme temperature variations.
For maximum flexibility the measuring range is user – programmable. You can also select the unit, no matter if it is ppb, ppm, % LEL or % volume.
Easy installation and removal
The control module is mounted on a standard DIN rail. With an optional power rail you can interface the 24 V DC power and the alarm signals. The modules can easily be added or removed from the rail, without an impact to the neighboured modules. You can program one of the modules to operate as a common alarm module. Even this function can be programmed just by push button. The application of a control module as a common alarm module is a very useful feature. It displays when any of the modules goes into Alarm 1, 2 or system alarm, and controls peripheral alarm devices.
All electrical contacts are located easily accessible on the front side. The terminals for alarm signals, analog output, sensor head connection run into 6 pluggable terminal blocks. This makes not only the first installation quick and easy, but also any service event or system modificatiA module can easily beon.
Intuitive User Interface
You want a gas detection system that needs little or no attention. No matter if setting the initial parameters or performing scheduled calibrations or proof tests: The handling shall be safe, quick and easy. The password – protected Statox 503 software structure is so clear, that most menu items are self – explanatory. The “Reset” button brings you back into the measuring mode at any time. Even if you have to interrupt your work and forget to reset, the watchdog function returns the system into the measuring mode, if no button has been pushed for a while. An additional switch allows you to trigger an out of schedule Statox 560 self – test
Functional safety paired with utmost system flexibility
The Statox 503 complies with the standards DIN EN 61508 and 61511 functional safety, level SIL 2. In connection with any SIL 2 sensor head you can create a complete gas detection system for combustible or toxic gases complying with SIL 2 standard. In larger installations signals of gas detectors often run into SIL certified process control systems, in smaller plants there is a need for a control module complying with SIL requirements. As any combination sensor head / control module forms a complete gas detection system, this system closes the gap. It is expandable without limits, and there is no restriction to the mix of sensor heads connected.
Connecting other front ends
The versatility of the Statox 503 does not end with gas detection. You can connect any front end providing a 4 – 20 mA analog signal or a Wheatstone bridge signal. So you can create your own compact control system for a variety of sensors with just one type control device.
Useful accessories such as calibration adapters, intrinsically safe repeaters, Power supplies etc. complete the system.
