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.

The Rational Solution: Bernstein safety relays for all applications
Bernstein AG offers a complete range of products to suit your particular application, from the safety switch to the safety relay. Our SCR safety relays (safety gate monitoring devices) are designed to reliably monitor input signals, e. g. those generated by Bernstein limit switches, safety-switches, -interlocking switches, -rope pull switches, -sensors or two-hand controls.
Bernstein SCR relays are housed in slim-line DIN rail housings, but despite their compact dimensions they have a huge range of applications right through to control category 4 in accordance with EN 945-1.
As defined by this standard, the SCR relays monitor the correct position and reliable operation of inputs from the safety sensors or safety switch contacts. Evaluation of this information is made and the safety outputs controlling the power elements such as power contactors or frequency converters will either stop the machine in an emergency or allow re-start when safe to do so. A further check of ‘power elements’ correct stop function is made via the feedback loop.

RET615 is a dedicated transformer protection and control IED for power transformers, unit and step-up transformers including power generator-transformer blocks in utility and industry power distribution systems. RET615 is a member of ABB’s Relion® product family and part of its 615 protection and control product series. The 615 series IEDs are characterized by their compactness and withdrawable design. Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability between substation automation devices.
RET615 is the ultimate protection and control IED for two-winding power transformers and power generator-transformer blocks. RET615 is available in four standard configurations to match the applied transformer neutral earthing principles with either high impedance or numerical low impedance restricted earth-fault protection schemes. CT ratio differences and phase shifts of all commonly employed power transformer vector groups are numerically compensated for. The standard RET615 configurations feature also local or remote control of the transformer HV side circuit breaker.
Due to the standard configurations of RET615 for the transformer protection, the IED can be rapidly set up and commissioned, once it has been given the application-specific settings.
RET615 genuinely supports the new IEC 61850 standard for inter-device communication in substations. It also supports the industry standard Modbus® protocol, and the well-established DNP3 and IEC 60870-5-103 protocols.

RED615, member of ABB's 615 product series, is a phase-segregated two-end line differential protection and control IED perfectly harmonized for utility and industrial power systems, including looped and meshed distribution networks with or without decentralized power generation. Re-engineered from the ground up, the new 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation equipment.
RED615 provides phase-segregated high speed, longitudinal differential protection for overhead line and cable feeders in distribution networks. Two RED615s interconnected over a communication link form an absolutely selective unit protection scheme. Protection of ring-type and meshed distribution networks generally requires unit protection solutions, also applied in radial networks containing distributed power generation.
Due to the ready-made adaptation of RED615 for the line differential protection, the IED can be rapidly set up and commissioned, once it has been given the application-specific IED settings. If the IED needs to be adapted to the special requirements of the intended application, the flexibility of the RED615 allows the IED's standard signal configuration to be adjusted.
