HESG447388R0001 70AA02B-E Contact Card  

Product Details Introduction

HESG4477388R0001 70AA02B-E Contact Card (Contactor Interface Control Card) Core Points

This model is a dedicated interface control card for ABB industrial contactors, adapted to contactor on-off logic and status feedback, focusing on precise control and safety protection of industrial electrical circuits. The 15 differentiated core points are as follows:

Compatible with ABB 70AA series contactors, serving as the interface core between contactors and control systems, to achieve signal conversion and drive control

Integrated contactor coil drive circuit, compatible with industrial standard control voltage, stable output current, ensuring reliable contactor engagement

Built in coil back electromotive force suppression module effectively absorbs the reverse voltage when the coil is powered off, avoiding component damage

Configure a contact state detection circuit to real-time collect the disconnection status of the main contact point of the contactor, and achieve closed-loop feedback control

The main circuit and control circuit are electrically isolated, and the isolation voltage meets industrial standards to resist surges and electromagnetic interference

Supports overcurrent and overload protection, quickly cuts off the drive signal in case of abnormal load, protects the contactor and control circuit

Equipped with LED status indicator lights, displaying information such as coil power supply, contact status, fault alarms, etc., for easy on-site inspection

Standard DIN rail installation, snap on fixation, suitable for compact deployment next to contactors in control cabinets, easy to install

The wiring terminal adopts anti loosening design, adapted to the vibration environment of industrial sites, and reduces the risk of faults caused by loose wiring

Compatible with mainstream PLC systems such as ABB AC31, supporting Freelance Control software for parameter configuration and debugging

Suitable for motor control categories such as AC-3, meeting the control requirements for start stop, forward and reverse rotation of small and medium-sized asynchronous motors

Industrial grade wide temperature design, with a working temperature range covering -25 ℃ to+70 ℃, suitable for harsh high and low temperature conditions

Using flame-retardant materials and components that comply with IEC/EN safety standards to enhance the operational safety of electrical systems

Support hot swapping function, no need to shut down the entire system during replacement, reducing maintenance downtime

Low power design, no need for additional cooling devices, can operate stably for a long time, suitable for long-term continuous production scenarios
