FAQ
Q1：What is the relationship between IS200SAMBH1ABA and IS200VAMB?A1：IS200SAMBH1ABA is an acoustic monitoring terminal board, responsible for the conversion and filtering of on-site sensor signals; IS200VAMB is an acoustic monitoring input board. The two are used in combination. Signals collected by SAMBH1ABA are transmitted to VAMB for analog-to-digital conversion and processing, forming a complete acoustic monitoring link.
Q2：Is this terminal board hot-swappable?A2：Yes, it supports hot swapping. Its modular design complies with the hot-swap specifications of Mark VI/VIe system. It can be replaced without system shutdown, reducing maintenance risks and downtime.
Q3：What are the requirements for operating ambient humidity?A3：Relative humidity: 5%–95% (non-condensing). Condensation shall be avoided to prevent circuit short circuit or corrosion. Cabinet moisture protection is required in long-term high-humidity environments.
Q4：What types of sensors can be directly connected?A4：It is compatible with 2-wire acoustic sensors, vibration sensors, microphones and other devices. The output voltage signal range shall match the board input specification (10Hz–20kHz), and direct connection of IEPE-type sensors is supported.
Q5：How to troubleshoot quickly in case of failure?
A5：
1. Check whether the 24VDC power supply is normal;
2. Verify terminal wiring and sensor status;3. Use the built-in system diagnosis function to check channel status;4. Detect whether the EMI filter is damaged;5. Conduct replacement test with a spare part of the same model to locate faults on the board card or external link.
