ABB Terminal Board NTDI01

ABB terminal board NTDI01 is the core electrical connection component of ABB frequency converter and transmission system, specially designed for ACS880, ACS580 and other series, providing safe and reliable signal transmission and power distribution interface. The terminal board integrates insulation protection and modular structure to simplify equipment wiring and reduce installation error rate.

Core functions and technical advantages

Secure connection:

Rated voltage 690V AC/DC, impulse voltage 6kV (in accordance with IEC 60664)

Flameproof and Flame Retardant (UL 94 V-0), finger-tight design for safe operation

Flexible expansion:

Supporting multi-channel expansion of 24V DC control signal, analog I/O and relay output

Plug-in terminal blocks support quick change (tool-free buckle design)

Anti-interference design:

Built-in EMC shielding layer to reduce electromagnetic interference of frequency converter on control signal

Partition isolation layout to avoid high and low voltage line crosstalk

Typical application scenarios

Frequency converter control circuit: PLC signal access, start/stop/fault feedback, speed setting

Sensor interface: PT100 temperature, pressure transmitter, encoder power supply

Linkage of external equipment: relay extension, brake unit control, safety chain circuit
