Since the pressure is insufficient to actuate the pressure switch, its contact remains in the “normal” state (closed). This sends power to relay coil CR1, thus actuating contact CR1-1 and holding it in the open state. With CR1-1 contact open, thealarmlamp receives no power. In this ex...
thus actuating contact CR1-1 and holding it in the open state. With CR1-1 contact open, the alarm lamp receives no power. In this example we see the pressure switch in its “normal” state but the relay in the actuated
Each relay A to E has four contacts, but additional contacts may be provided for holding circuits if storage is required. A complete circuit diagram of the relay contacts is given, Fig. 2a (not shown). The circuit is described as completely safe in that no conditions of operation either ...

The output signal e.sub.2 of the peak value holding circuit 15 is supplied to a detecting means, such as the level detector 16 having an operational amplifier IC.sub.1 and a zener diode ZD.sub.1, which is connected between the input and output terminals of the operational amplifier IC....
Since being founded, the company has been insisting on the theoretic guideline of "science&technology is the first productive force" and holding up brand strategy as the guide, relying on forward understanding about power supply technology, perfect craft and unwearied pursuing to qual...
MRL1 Lock-out Relay Manual MRL1 – Lock-out Relay Manual MRL1 (Revision A)
In the wiring configuration below, the universal fuel pump controller PURPLE wires are set up as a ground switch circuit. One of the PURPLE wires goes to ground and the other becomes an output and gets connected to the respective relay circuit to trigger the relay "ON." Using this diagram,...
A drive circuit responsive to an applied electrical signal for generating a voltage to control the actuation of an electromagnetic relay is disclosed. The voltage has a first and a second level for picking-up and holding-in, respectively, the relay. The first voltage level has a peak value wh...
said unit having a two-leveled construction in which the terminal block is disposed on a lower level of the construction and the relays are disposed on an upper level of the construction such that the relays are located approximately above the terminal block, and wherein the two holding members...
