1440-TB-H 是一个标准的动态测量模块

Allen-Bradley 1440-TB-A 模块是一个标准的动态测量模块，是 Allen-Bradley XM 系列的一部分。该模块属于一组分布式机器状态保护和监控设备。1440-TB-A 模块是一个 2 通道通用监视器，用于测量动态输入，如压力、振动、位置和应变测量。该模块主要监测旋转设备中的外壳、轴和基座振动。可接受的输入包括非接触式涡流探头、速度传感器、标准集成电子压电 （IEPE） 加速度计以及直流或交流电压输出测量设备。此外，1440-TB-A 模块还支持转速计输入，提供速度测量以及阶次分析功能。

1440-TB-A 模块与大多数转速计信号源兼容，如无源磁探头、涡流探头和其他转速计传感器（有源和无源）。输出包括可通过 DeviceNet 网络进行通信的数字测量、两个 4 至 20 mA 模拟输出和一个板载继电器。每个振动输出通道和转速计输入都带有一个输出缓冲器。1440-TB-A 模块支持高 级报警继电器逻辑以及关键振动参数的板载处理。

此外，1440-TB-A 模块可以独立运行，也可以将数据分发到集成控制和自动化系统。这些系统可在机器发生故障时保护机器，或者通知操作员异常情况或故障。1440-TB-A 模块的操作需要一个 XM-940 动态测量模块终端单元，该单元未包含在包装中。XM-940模块基础单元是安装在DIN导轨上的基础单元，为XM振动模块所需的现场接线提供端接，其中包括1440-TB-A标准动态测量模块。

The Allen-Bradley 1440-TB-A module is a standard dynamic measurement module that is part of the Allen-Bradley XM series. The module belongs to a set of distributed machine condition protection and monitoring devices. The 1440-TB-A module is a 2-channel universal monitor for measuring dynamic inputs such as pressure, vibration, position and strain measurements. The module monitors shell, shaft and base vibrations in rotating equipment. Acceptable inputs include non-contact eddy current probes, speed sensors, standard integrated electronic piezoelectric (IEPE) accelerometers, and DC or AC voltage output measurement devices. In addition, the 1440-TB-A module also supports tachometer input, providing speed measurement and order analysis functions.

The 1440-TB-A module is compatible with most tachometer signal sources, such as passive magnetic probes, eddy current probes and other tachometer sensors (active and passive). Outputs include digital measurements that can be communicated over the DeviceNet network, two 4 to 20 mA analog outputs, and an onboard relay. Each vibration output channel and tachometer input has an output buffer. The 1440-TB-A module supports advanced alarm relay logic and on-board processing of critical vibration parameters.

In addition, the 1440-TB-A module can operate independently or distribute data to integrated control and automation systems. These systems protect machines in the event of machine failure, or notify operators of anomalies or failures. The operation of the 1440-TB-A module requires an XM-940 Dynamic Measurement module terminal unit, which is not included in the package. The XM-940 Module base unit is a base unit mounted on a DIN rail that provides terminations for the field wiring required for XM vibration modules, including the 1440-TB-A standard dynamic measurement module.
