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
Voltage measurement relay 3-phase for over and under voltage
Carlo Gavazzi
Voltage measurement relay 3-phase for over and under voltage
Art. no.: 3864692
3-phase monitoring relays for phase sequence/Phase break and Over-/Under Voltage for mounting on DIN rails or 11-pin base.
Functional description
The relay is pulled when the phases or the phases + 0 are within the set limits, the relay falls if the limit values are passed after the set time delay (0.1-30s). The relay also monitors phase breaks and phase sequence, at the wrong phase sequence or phase break the relay falls without time delay.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.3 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is on and Red flashes during the time, and is lit with a steady light in alarm.
Miniature relay C7 and C9 QRCplus
Releco
Miniature relay C7 and C9 QRCplus
Art. no.: 4016417
A real compact relay with base, when you are looking for a small relay with the big relay's contact data. With touch-protected test button which is non-locking with pressing and remaining in extracted mode. Accessories include test buttons using only the non-locking function or blind plug (if the test function is not desired). The test button is colour-coded, red for AC and DC blue, as well as the most common voltages 230VAC, 24VAC and 24VDC has its own colour shades. The coil input voltage is clearly marked on the relay front and on the coil. CE certified.
Types C7A ... and C9A.. have mechanical indication of actuated contacts.
Types C7A..X and C9A..X.. have mechanical indication of activated contacts and LED indication of actuated relay coil

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.

Industrial relay IRC C12 2-pole
Releco
Industrial relay IRC C12 2-pole
Art. no.: 4016984
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.
