Description:

The Allen-Bradley 1440-TB-A Terminal Base Unit is designed specifically for the XM-124 Standard Dynamic Measurement Module (catalog number 1440-SDM02-01RA). It provides all necessary field wiring terminations, including 24V DC power input, two dynamic transducer inputs with buffered outputs, one tachometer input with buffer, two isolated 4…20 mA outputs, one onboard relay (SPST, Form A) contacts, DeviceNet communication ports (CAN_H, CAN_L, DNet V+, DNet V–, shield), a serial port (TxD, RxD, RTN) for local configuration, and switch inputs for setpoint multiplication and remote relay reset. The base unit mounts on a standard 35 mm DIN rail or directly onto a panel/wall. It features a side connector that allows interconnection with adjacent XM modules, simplifying external wiring by sharing power (24V DC, up to 3 A) and DeviceNet signals (300 mA max). The 1440-TB-A is conformally coated and certified for use in Class I Division 2 hazardous locations and ATEX Zone 2 environments.

Key capabilities

  • Designed exclusively for the XM-124 Standard Dynamic Measurement Module

  • DIN rail (35 × 7.5 mm) or panel/wall mounting options

  • Side connector for daisy-chaining power (24V DC, up to 3 A) and DeviceNet signals to adjacent XM modules

  • Terminal block assignments include:

    • 24V DC power input (terminals 43, 44, 45)

    • Two dynamic transducer inputs with buffered outputs (Xducer 1/2, Buffer 1/2)

    • One tachometer input with buffered output (Tach/Signal In, TACH Buffer)

    • Two isolated 4…20 mA outputs (300 Ω max load)

    • One onboard relay (Normally Open contact) with common

    • DeviceNet connections (CAN_H, CAN_L, DNet V+, DNet V–, shield)

    • Serial port (TxD, RxD, RTN)

    • Setpoint multiplier and remote relay reset switch inputs

    • Chassis ground terminals

  • Operating temperature range: –20…+65 °C (–4…+149 °F)

  • Storage temperature: –40…+85 °C (–40…+185 °F)

  • Humidity: 5…95% noncondensing

  • Conformally coated circuit boards (IPC-A-610C)

  • UL, c-UL, ATEX, IECEx, CE, RCM, KC, CCC certifications for hazardous locations

  • Terminal screw torque: 0.8 N·m (7 lb·in)

Applications

  • Mounting and wiring the XM-124 Standard Dynamic Measurement Module in machine condition monitoring systems

  • Vibration, pressure, strain, and position monitoring for rotating machinery (turbines, compressors, pumps, fans, generators)

  • Thrust position and eccentricity monitoring

  • Spike energy (gSE) measurements for bearing and lubrication fault detection

  • Integration into DeviceNet networks via the terminal base’s communication ports

  • Use in hazardous locations (Class I Division 2, ATEX Zone 2) with proper enclosure

Quality Assurance

100% brand new original. 1-year warranty. In stock for fast delivery (1-3 days).

Frequently Asked Questions:

Q1: Which XM module is compatible with the 1440-TB-A terminal base?
A1: The 1440-TB-A is designed specifically for the XM-124 Standard Dynamic Measurement Module (catalog number 1440-SDM02-01RA). It is not compatible with other XM modules.

Q2: Can the 1440-TB-A be mounted on a DIN rail?
A2: Yes. It mounts on a standard 35 mm × 7.5 mm DIN rail (e.g., Allen-Bradley 199-DR1 or 199-DR4). It can also be mounted directly to a panel or wall using #6 self-tapping screws.

Q3: Does the terminal base provide power to adjacent modules?
A3: Yes. The side connector passes 24V DC power (up to 3 A total) and DeviceNet signals to neighboring XM modules, allowing daisy-chaining without separate wiring for each module.

Q4: What is the operating temperature range?
A4: –20 °C to +65 °C (–4 °F to +149 °F). Storage temperature: –40 °C to +85 °C (–40 °F to +185 °F).

Q5: Is the 1440-TB-A approved for hazardous locations?
A5: Yes. It carries UL/c-UL Class I Division 2, ATEX Zone 2 (Ex ec IIC T4 Gc), IECEx, and CCC Ex certifications. It must be installed in an appropriate enclosure (minimum IP54 for ATEX).

Q6: What wire sizes are supported?
A6: 22…14 AWG (0.34…2.1 mm²) solid or stranded copper wire, rated at 75 °C or higher. Recommended strip length: 8 mm (0.31 in.). Soldering is not permitted. Signal connections should use shielded wire.
