SAFETY SHUTDOWN & CONTROL SYSTEM
Protection for Equipment, Fields, Environment

Safety and reliability are critical factors in designing Emergency Shutdown Systems (ESD) and the fire and gas detection and protection systems These systems bring production facilities and refinery units to a safe state after an unpredictable hazardous event, and maintain that state until other-wise commanded. Whatever the cause for operating abnormalities. This  system is designed to consistently and automatically protect personnel, environment and equipment. We  do not take false or unnecessary actions, rather the system accelerates the process in which the plant will return to its normal operating state.

We conduct a hazard analysis to determine the required level of safety integrity for your plant. The analysis also determines which type of safety protection is required, such as an Emergency Shutdown system. The next task is to decide the appropriate Safety Integrity Level (SIL) the system must meet. This safety system has many features that make it suitable for use in advanced safety applications, including safety I/O boards, programming elements and highly advanced diagnostics. It is also suitable for use in smaller applications where it can handle both process control and safety.  The safety controller is designed to meet any application requirements in safety. It has two control branches that work in parallel, yet independent of each other. Each control branch is able to set field output signals when its extensive diagnostic control gives an active permissive signal. Also, the safety controller has fully triplicated architecture, from input modules to output modules. It uses a 2 out of 3 voting principle, and is designed for maximum safety and availability, maximizing uptime for the plant. The ABB TMR system offers fault-tolerant and fail-safe operation, and has the fastest scan time of any TMR system with `availabilities exceeding 99,999%.

 

 Bender - Safe and secure power supply and everything runs perfectly.
Modern technology has an important influence on both our lives and our work - whether in the automated industry, public transportation, building services systems or in hospitals. Could we do without electrical power in today’s modern technology?

Secure power supply is the be-all and end-all of high tech. particularly in critical areas. Initially in areas subject to explosion hazards, such as mining, later on in hospitals and today in many applications.

Medical engineering
In hospitals patient care is of paramount importance. So it is the medical staff`s task to ensure that patients are treated effectively and receive the highest level of care. But even a short power interruption may expose patients to hazards or impair a successful therapy or diagnosis. The patient deserves the best possible protection using the latest technology. Also costs and deadlines have to be taken into account when planning electrical installations in hospitals.
Considering this, BENDER together with experienced planning engineers developed the MEDICS system for these critical care areas.
A new system offering a maximum of safety through the monitoring of electrical installations in hospitals, operating theatres and locations for medical use. In this way, time and cost-saving planning, installation and operation can be achieved.
In this category there are the following subcategories and products:
International standards Isolating transformers
Switchover and monitoring module Monitoring devices
Remote alarm indicators and operator's panels Switchgear cabinets
Measuring and monitoring relays:
Thanks to sophisticated technology and perfected conception Bender measuring and monitoring relays are ideally suited for monitoring electrical installations in various application fields. That ensures early detection of possible faults and potential sources of danger and helps to reduce cost and production downtimes to a minimum.
In this category there are the following subcategories and products:
Voltage relays AC/UC Phase sequence relays
Voltage relays DC Frequency relays
Current relays AC Automatic restart relays
Current relays DC Other measuring and monitoring relays
Asymmetry relays Accessories
Residual current monitoring:
Residual current monitors detect residual currents at an early stage and provide alarm indication when the threshold is exceeded. This helps to reduce cost-intensive interruptions to operation and effectively supports maintenance.
In this category there are the following subcategories and products:
RCM for AC TN/TT systems Residual current location system
RCM directionally for AC IT systems Portable residual current location system
RCM for AC/DC sensitive TN/TT systems Accessories
