Advantageous Features
Modular hot-swappable design
The XM-940 1440-TB-A module can be replaced by plugging in and unplugging, without the need for rewiring. The maintenance time is shortened from hourly to a minute level, reducing downtime losses.
Signal conditioning and anti-interference
Built-in constant current source excitation circuit (4mA), supporting ICP/IEPE type accelerometers. EMI/RFI shielding design ensures accurate transmission of vibration signals in industrial electromagnetic environments.
Terminal types available
Spring cage type terminals: tool-free quick connection, anti-vibration loosening
Screw terminals: firmly pressed, low contact resistance
Choose flexibly according to the on-site environment.
Integrated multi-signal interfaces
Single base supports:
2 channels of dynamic vibration signals (acceleration/velocity)
1 channel of rotational speed/key signal
1 channel of temperature signal (RTD/thermocouple)
1 channel of 4-20mA process input
Original signal buffer output
BNC interface outputs the original vibration signal, which can be directly connected to portable analyzers or third-party acquisition systems, facilitating on-site diagnosis and system expansion.
Hard-wired relay output
Independent relay dry contacts, vibration over-limit directly trigger interlock protection. Not dependent on communication networks, meeting high safety level application requirements
Installation and Usage Tips
Installation Steps
DIN Rail Installation: Align the base snap-in with the DIN rail and press it in place for fixation
Grounding Connection: Connect the grounding terminal of the base to the system grounding busbar securely
Sensor Wiring: Connect the sensor cable according to the terminal markings, with the shielding layer grounded at one end
Power Wiring: Connect to a 24V DC power supply. Pay attention to the correct polarity.
Module Insertion: Align the XM-940 module with the rail slot and push it in to the locking position
Usage Precautions
Sensor Cable: It is recommended to use a double-shielded cable. The outer shield should be grounded, and the inner shield should be left unconnected or grounded for a signal
Terminal Torque: For screw terminals, the recommended torque is 0.5-0.6 N·m. Over-tightening may damage the terminals
Module Insertion and Removal: Before plugging or unplugging, ensure the power supply is normal.
