Contact protection relays are used in type 821 contact devices. They increase the switching reliability and switching capacity of electromechanical contact devices and lower their contact voltage. Undesired switching operations of contact devices caused by vibrations are significantly reduced by a drop-out delay of 0.5 sec. On the side of the contact they operate with a lower control voltage, however, on the output side they can be highly loaded. Contact protection relays consist of a power supply unit, control unit, switching amplifier and relay output. The contacts are supplied by a control unit with 35 to 40 V clocked DC (i.e. only every hundredth switching occurs under voltage). This enables the optimum contact protection and switching reliability for millions of switching cycles.

      NHP offers a range of control relays and timers that can be used in conjunction with a conventional automation system to switch higher loads or in stand alone applications where the only basic single function control is required.

the 6md66 high-voltage bay control unit is the control unit for high voltage bays from the siprotec 4 relay series. Because of its integrated functions, it is an optimum, low-cost solution for high-voltage switch bays. The 6md66 high-voltage bay controller unit also has the same design (look and feel) as the other protection and combined units of the siprotec 4 relay series. Configuration is performed in a standardised way with the easy-to-use digsi 4 configuration tool.for operation, a large graphic display with a keyboard is available. The important operating actions are performed in a simple and intuitive way, e.g. Alarm list display or switch gear control. The operator panel can be mounted separately from the unit, if required. Thus, flexibility with regard to the mounting position of the unit is ensured. Integrated key-operated switches control the switching authority and authorisation for switching without interlocking. High-accuracy measurement ( 0.5 %) for voltage, current and calculated values p and q are another feature of the unit.   application integrated synchro-check for synchronized closing of the circuit-breaker breaker-related protection functions (breaker failure 50bf, auto-reclosure 79) automation can be configured easily by graphic means with cfc flexible, powerful measured-value processing connection for 4 voltage transformers, 3 current transformers, two 20 ma transducers volume of signals for high voltage up to 14 1 ½-pole circuit-breakers can be operated up to 11 2-pole switching devices can be operated up to 65 indication inputs, up to 45 command relays

Electrical device control ESIM252 allows to expand existing security panels and systems with GSM capabilities. Adds SMS and auto dial alerts a call is dialled and an SMS message is sent to the programed phone numbers. ESIM252 allows prerecord 10 different voice messages up to 15 sec. length each for different user and situation. It is possible to remotely control electric equipment by a call too. Easy configuration ESIM252 supports configuration through USB and SMS. There is an Eldes configuration tool for quick and easy setup. Possibility to add users and change settings later with simple short messages too. Comfortably access event logs through the Internet. Supports non GSM control panels ESIM252 can add GSM and GPRS functionality to almost any security control panel. Expand system’s capabilities with SMS alerts, automatic phone calls and Internet event logs. ESIM252 GSM has 5 inputs and 2 outputs. Business flexibility Up to 5 users can use one ESIM252 GSM system. It is possible to prerecord up to 10 auto dial messages. Configure ESIM252 so that different users would get alerts only important to them or about devices they are responsible for. Choose between auto call or SMS, maybe some will prefer to receive both + status alerts about auto reboots and device faults. For example: get informed when food vending machine is full of coins by getting an SMS, this will help to avoid unnecessary checking, or monitor ventilation system in your shopping center with accuracy. The system reports about electronic devices failures too.
