The SafeC 200 safety relay takes over the evaluation of all standard safety components such as e.g. light curtains, emergency STOP buttons, safety edges or interlock switches.
Thanks to the high-performance integrated safety circuits of the SafeC 200, for the majority of applications no supplementary relay is needed. Additionally multiple status outputs ensure a simple communication with every standard SPS and guarantee a reliable and faultless controlling. Even the most demanding of applications relating to Safety Category 2 of EN 954-1 are fulfilled by the SafeC 200 safety relay.
The configuration of a SafeC 200 module to meet the requirements of your own machine is accomplished by using the OptiLink interface. The corresponding “Safety Configurator” software, is available and can be downloaded free of charge at www.cedes.com. With the help of the software, no special programming knowledge is needed, and functions like start mode, stop delay times, “Blanking” and “Safety Prevention” can be easily configured.

Safety-implemented circuits must be control reliable as mandated in U.S. and European standards. Control reliability is not provided by simple redundancy. There must also be monitoring of the safety circuitry to assure that redundancy is maintained. Monitoring may be achieved by using Omron STI safety monitoring relays that range in function from two-hand palm button control to dual channel input units with time-delayed outputs that conform to ANSI B11.19-2003, Section 6.1 for Performance of the Safety Related Function(s). All safety relays carry the CE mark and are designed to incorporate three points of safety in their operation to meet both European and U.S. requirements. All safety relays are UL and C-UL listed.

MIB High Impedance Busbar Differential Relay
MIB High Impedance Busbar Differential Relay
The MIB, a member of the M II family of economical and highly functional digital protection relays, is a microprocessor based relay that provides three phase high impedance differential protection for Substation Bus-bars of any voltage level.
Use the MIB also to protect electrical machines like transformers, generators or motors against restricted earth faults.
Basic protection functions features include a high impedance differential protection unit with a tripping time of 1 1/2 cycles. Stability against external faults is guaranteed thanks to the use of a stabilizing resistor. The unit includes a set of MOVs (Metal Oxide Varistors) provided to clamp the secondary peak voltage below 2kV during fault conditions.
The relay includes open CT detection which provides an alarm when it detects sustained current unbalance conditions, issuing a warning signal and blocking the operation of the unit.

The Current Protection Relay (IPR-A) has been designed to measure the line and ground RMS currents under normal conditions or under disturbances. The current signals are sensed throughout current transformers (CT) from each line. This information is internally processed by the microprocessor, to take the current protection actions defined under ANSI, IAC or IEC standard. The different functions provided by the IPR-A may be classified into the following groups:
Applications:
* Primary and backup protection for power plants, utility and industrial distribution systems.
* Protection of transformers, overhead lines, cables and generators.
* Permits the opening of the switch/disconnector within the limits of its capacity, those identifying the excess (e.g. straight short-circuits), leaving the circuit interruption to the back-up fuses.
Protection:
* CT primary ratio selectable in 5 amp steps (10 A to 5000 A).
* Inverse time phase overcurrent (ANSI 51) and inverse time ground overcurrent (ANSI 51N/51G), with selection of curves according to ANSI, IAC or IEC/BS142, as follows:
Moderately inverse.
Standard inverse.
Very inverse.
Extremely inverse.
Definite time.
* Instantaneous overcurrent (ANSI 50).
* Instantaneous ground overcurrent (ANSI 50N/50G).
* Overload alarm adjustment to one level.
* Accumulated KA per phase on breaker interruption.
* 1 trip relay and 1 alarm relay.
* Loss of control volts relay.

SIPROTEC 7RW600 is a numerical, multifunction relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If it detects any deviation from the permitted voltage, frequency or overexcitation values, it responds according to the values set.
SIPROTEC 7RW600 can be used for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops. Voltage and frequency thresholds can also be monitored.
This voltage, frequency and overexcitation relay can be used to protect generators and transformers in the event of defective voltage control, of defective frequency control, or of full load rejection, or furthermore islanding generation systems.
