PNOZ s5 C 48-240VACDC 2 n/o 2 n/o t

Introduction:

Safety relays typically adopt a dual channel signal design to ensure that they can only function properly when both channel signals are normal. Once any channel signal is disconnected during the working process, the safety relay will immediately stop outputting until both channel signals return to normal and the safety contacts, namely 13-14 and 23-24, are completed. These two contacts are normally open and suitable for the requirements of the safety circuit. In addition, a transistor output contact Y36-Y37 is provided. The PNOZ X2P also has six safety circuit wiring terminals starting with "S" (Safe), including S11, S12, S21, S22, S33, and S34. These terminals can only resume operation after two safety reset operations are connected internally. Taking PNOZ X2P as an example, it is equipped with two channels (INPUT) and one start/reset channel. It is worth noting that the Y36 and Y37 contacts are also important components of the reset circuit, and a series of conditions need to be met to achieve reset startup.

Working Principle:

1. Signal input: The safety relay is connected to a sensor or switch in the circuit,

Received control signals from the circuit.

2. Signal detection: Safety relays detect and analyze input signals, and make judgments

Is there any abnormal condition in the circuit. These abnormal situations may include overload, short circuit

Grounding faults, etc.

3. Output control: If the safety relay detects an abnormal circuit, it will quickly cut off

Power supply to prevent the circuit from continuing to operate. Usually, the output of a safety relay is a

The switch that disconnects the circuit can cut off the power supply.

4. Feedback signal: Once the safety relay cuts off the circuit, it will send a feedback signal

Notify the operator that there is a problem with the circuit and trigger the corresponding alarm system.
