Timer relay a-collection
a-collection
Timer relay a-collection
Art. no.: 4098560
Function Op, operation delayed: Time calculation starts when the contact on the active input is closed. After the set time the relay switches on regardless of whether the contact on the active input is closed or open. If the contact is closed again after the time calculation has been switched off, the relay turns off and the time calculation starts again.
Function in, delayed disconnection: Time calculation starts and the relay opens when the contact on the active input is closed. After the set time the relay switches off regardless of whether the contact on the active input is closed or open. If the contact is closed again after the time calculation has been completed, the relay turns on and the time calculation starts again.
Function Dr, drop out delayed: The relay opens when the contact on the activation input is closed. When the contact is broken the time calculation starts. After the set time, the relay turns off. If the contact on the active input is closed while the time calculation is being made, the time calculation is reset while the relay is still turned on.
Flashing Function - Function R: (ON time first), (Function, Rb, OFF time first). When the control voltage is connected, the time starts to be calculated, when the period has expired the relay disengages. When the time for the disengaged relay has expired, the relay opens. This process continues as long as the control voltage is connected. The time for the rest and running time is equal. All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.
Indication: 2 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is closed and flashes during the time calculation
Transmitter Sesam 800
Åkerströms
Transmitter Sesam 800
Art. no.: 3775303
Sesam 800 transmitters are very robust and user-friendly and are available in six models, where Sesam 800 Large 99 is the most advanced transmitter with the option to control up to 1000 receivers. In Large 99, there is also the option to protect the installation with a four-digit PIN code, which means that only authorised people can unlock and use the functions. Large 99 also has support for group-IDcoding and can be used together with our in-house developed configuration tool Sesam MC Manager which simplifies installation, configuration, testing and maintenance of large-scale plants. The receivers are equipped with a vibration absorbing edge and have distinct, easily manoeuvred buttons of high quality, which can manage over 1 million presses.

Industrial relay IRC C12 2-pole
Releco
Industrial relay IRC C12 2-pole
Art. no.: 4016983
2-pole switching contacts, 5A (AC1). The relay has a colour-coded test button that is both locking and non-locking. Function indication with both flag and LED by default. Coil voltage is marked on the relay front. Nameplate for individual marking is on the relay and socket. The relay has robust connection pins (2.5 mm).
The pedestal has I/O configuration with connection and output on each side. The pedestal is suitable for breakable yoke (S12BB), which makes it possible to block mount multiple sockets, and thereby facilitate the wiring. The bases have robust connections and connection screws. The clamp that secures the relay in the socket is standard. All this makes the IRC one of the most flexible interface relay systems on the market.
CPUs Standard Simatic S7-300
Siemens
CPUs Standard Simatic S7-300
Art. no.: 4500369
Modular expandable PLC for smaller or medium system solutions with extensive range of modules for optimisation and adaptation to different types of applications. Fully integrated in Totally Integrated Automation:
- Configuration and programming with STEP 7
- Network structure with MPI, PROFIBUS and PROFINET.
Complete family with CPUs from start CPUs to powerful CPUs with high processing speed which allow short machine cycle times. Depending on the application there are CPU communications interfaces for industrial Ethernet and Profibus. Even available in designs for outdoor applications with extreme conditions, and a Fail-safe design. All Profinet CPUs (PN) have an integrated Web-Server with amongst others access to the CPU’s diagnostic information and variable tables.

Safety switch plastic encased SA 16-25 A
Norwesco
Safety switch plastic encased SA 16-25 A
Art. no.: 3164310
Enclosed load switch/disconnectors in accordance with IEC 60947-3, e.g. for use as safety switch where required. In accordance with applicable regulations, a safety switch must be connected in a main circuit to disconnect the plant section during mechanical or electrical work and to prevent unintentional reconnection of the plant while work is in progress. Since a safety switch is only to be used to disconnect a plant section, the plant’s electrical circuit must have both a switching device for start and stop, and a separate switching device as a safety switch.

• modern dirt-repellent form
• strong connection terminals with screws in screwed position
• generous connection space with plenty of room to run cables
• earth and neutral rail as standard, 4-pole with earth rail only
• necessary throttling nipples and standards-compliant
• signs are included as standard
