Purpose:
JC-13、 The 14 type impact relay (hereinafter referred to as the relay) is mainly used for alarm starting sound in various faults of relay protection and safety automatic device circuits. It is a repetitive action component of the central sound alarm circuit in power stations, substations, and related projects.

Relay model name:



Working Principle:
JC-13、 The 14 type relay consists of a transformer, measurement sampling pulse width detection, trigger memory, automatic reset, delayed action and delayed return, and voltage stabilization circuit. The logic diagram is shown in Figure 1.
When a certain circuit light sign lights up, current flows through the primary winding of the inverter of the relay, inducing a pulse voltage on the secondary winding of the inverter. This voltage is sent to the action measurement and return measurement circuits respectively. Since the action measurement only judges the output when the light is on, there is no output when the light is off, and the return measurement only judges the output when the light is off and there is no output when the light is on, the action measurement and return measurement will not have outputs at the same time. The measurement output is sent to the pulse width detector to avoid relay misoperation caused by induced voltage in the circuit. After determining the pulse width, it is sent to the trigger memory circuit, and the output of the trigger memory circuit is sent to the action delay and return delay circuits. After meeting the set time, it is output to the outlet relay.
Due to the memory function of the triggering circuit, when the light sign lights up for the first time, the relay will act. If the light sign lights up again, the circuit will no longer detect pulses until one of the light signs goes out. After the predetermined return time, the relay will return or be reset externally. The relay enters the loop state again.
The relay has a delay circuit for both action and return, aiming to ensure the interoperability of accident and warning signals in the starting audio system. At the same time, the relay is also equipped with an external reset interface. This relay can replace any current impact relay and save users the time relay used in the original equipment.

Application extension:
Due to the delay action and delay return time circuit in JC-13 and 14 relays, with delay action setting t1 and delay return setting t2, there are multiple applications that can be extended.
6.1 Signal triggered automatic reset
No reset button: After signal start t1, the relay starts, and after signal reset t2, the relay returns.
6.2 Manual Reset
After the signal starts t1, the relay starts, and after the hand returns, the relay returns.
6.3 Relay self resetting
The relay contacts are connected in series to the reset circuit. After the signal is activated t1, the relay starts, and after the relay acts t2, it returns.
