Power Supply

Nominal supply voltage: 24 V DC

Allowable operating voltage range: 18 V DC to 30 V DC

Typical operating current: 140 mA

Maximum operating current: 180 mA

Maximum power consumption: 4.3 W

The power supply circuit features galvanic isolation from all sensor signal circuits to enhance anti-interference performance.

Sensor Input Channels (Proximity Probe Interface)

Probe excitation voltage for 3300 series eddy current probe: -24 V DC

Nominal probe bias current: 4 mA DC

Valid probe gap signal input range: 0 ~ -24 V DC

Input impedance: Greater than 100 kΩ

Fully compatible with standard Bently Nevada eddy current transducer systems.

Analog Output

Isolated 4–20 mA DC signal output for vibration measurement

4 mA: Corresponding to the minimum measuring range limit

20 mA: Corresponding to the maximum measuring range limit

Maximum permissible load resistance: 600 Ω

Relay Alarm Outputs

Contact capacity: 3 A resistive load at 250 V AC; 3 A resistive load at 30 V DC

Adopts electrically isolated Form-C SPDT dry contact design for alarm output.

Digital Communication Interface

Supports internal backplane bus communication with bus-powered transmission mode. No additional external power supply is required for data communication.

1. Backplane Power Connection

The A6210 is a hot-swappable plug-in module designed for the AMS 6500 rack system. Both operating power and internal bus communication are automatically supplied through the rear rack backplane connector, eliminating the need for external power and communication wiring. Hot-swap operation is available under normal system operating conditions.

2. Eddy Current Probe Input Wiring (Channel 1 & Channel 2)

Connect Bently Nevada 3300-series proximity probes and matching extension preamplifiers to the module rear terminal blocks. Route the preamplifier signal output to the module’s sensor signal input terminals.

Signal specification: 0 ~ -24 V DC gap voltage signal

Wiring requirements: Adopt dedicated low-capacitance transducer cables; ordinary shielded wires are not allowed. The cable shield shall be single-point grounded at the rack cabinet side only. Dual-end grounding is prohibited to prevent ground loop interference.

3. Isolated 4–20 mA Analog Output Wiring (Per Channel)

Each measurement channel provides an independent electrically isolated 4–20 mA proportional analog output for transmission to DCS or PLC analog input modules.

Terminal definition: 4–20 mA (+) for positive signal, 4–20 mA (-) for negative signal

Wiring requirements: Use twisted shielded pair cables with the shield grounded only at the DCS cabinet terminal. The maximum allowable load resistance of the analog loop is 600 Ω.

4. SPDT Form-C Relay Alarm Contact Wiring

The module is equipped with two sets of Form-C SPDT dry contacts, corresponding to Alert and Danger alarm signals respectively. Each relay includes Common (COM), Normally Open (NO) and Normally Closed (NC) terminals.

Contact rating: 3 A resistive load at 250 V AC; 3 A resistive load at 30 V DC

Note: The relay contacts are passive with no internal power supply, requiring external user-provided control voltage. Signal cables must be separated from high-power motor cables to reduce electromagnetic interference.

5. Front Panel Auxiliary Interfaces

Buffered Sensor Output (BNC Socket)

Reserved for temporary oscilloscope signal measurement, applicable for high-impedance loads (>100 kΩ). Not applicable for long-term formal signal transmission.

Configuration Mini-DIN Port

Used for connecting a PC configuration cable to complete module parameter setup via dedicated software. It does not support continuous data transmission during system operation.

6. General Wiring Specifications & Rules

All wiring operations must be performed with the rack power off to avoid module burnout. Classify and lay sensor cables, analog signal cables and relay power cables in separate cable trays. Ensure complete and continuous shielding of all shielded cables without damage or breakage.

After wiring, calibrate the probe gap voltage and adjust the installation gap to the midpoint of the linear measurement range. Check and fasten all terminals with standard torque to prevent intermittent faults caused by loose connections. Do not apply AC voltage exceeding the rated specification to relay contact terminals.

7. Grounding Requirements

The module internal circuit is electrically isolated from field external wiring. The cabinet protective earth must be connected reliably. All transducer cable shields are strictly single-point grounded at the rack cabinet ground bar, and multi-point grounding is forbidden.
