ABB 216NG62A HESG441634R1/K
ABB 216NG62A (Order No.: HESG441634R1/K, mating fuse module: HESG216876) is an industrial‑grade 16‑channel relay digital output (DO) module. It belongs to the ABB Advant Controller 31 and REG216 relay protection system series. As an output module in the same family as 216VC62a, it is positioned for highly reliable switching in mature and general‑purpose applications. It provides safely isolated and individually protected digital outputs for industrial control systems, suitable for standard control loops in heavy industries such as power, metallurgy and chemical engineering.
I. Product Positioning
ABB 216NG62A (HESG441634R1/K) is an industrial‑grade 16‑channel normally open (NO) relay digital output module, mainly used for switching actuation in industrial control loops (driving contactors, indicator lamps, valves, alarm circuits).
The module features a classic design of fully isolated relay outputs plus individual plug‑in fuses, strictly compliant with IEC industrial safety and EMC standards. It is seamlessly compatible with ABB DCS, PLC and REG216 relay protection systems, delivering highly reliable, strongly isolated and quickly maintainable on/off control for field actuators. It is especially suitable for stable operation in proven mature production lines and power plant/substation protection systems, ensuring safe and trouble‑free system performance.

III. Core Functions
16 Standard Isolated Relay Outputs
16 independent normally open contacts, each capable of directly driving contactors, solenoid valves, indicator lamps and alarm circuits at 2A/250V AC (resistive) without additional intermediate relays, simplifying standard system design and reducing cost. Ideal for large‑scale, mature control loops.
2 kV Full Galvanic Isolation and EMC Noise Immunity
2 kV electrical isolation between channels and between channels and logic side, compliant with industrial EMC standards. Effectively blocks strong on‑site electrical interference and ground potential differences, preventing false triggering and module burnout. Suitable for strong electromagnetic environments such as power plants and metallurgical workshops.
Dedicated Fuse Module Protection (HESG216876)
Each channel is equipped with an individual plug‑in fuse integrated into the dedicated HESG216876 module. In case of short circuit or overload on one channel, only that fuse blows without affecting the other 15 channels or the entire module. Fuses can be replaced directly by plugging/unplugging without removing the module, greatly reducing downtime for maintenance.
Stable Response and General Sequential Control
Response time: turn‑on ≤ 10 ms, turn‑off ≤ 12 ms, meeting the general sequential requirements of most industrial motor start/stop, valve control and alarm triggering. Suitable for mature production lines without extreme speed demands.
Industrial‑Grade Reliability and System Compatibility
Wide operating temperature (-20℃ ~ +70℃), IP20 protection, suitable for standard 19‑inch racks. Modular design ensures full compatibility with ABB Advant Controller 31, REG216 relay protection systems and mainstream DCS/PLC platforms. It can directly replace legacy modules of the same type with low upgrade cost.
IV. Applications
As a classic DO module for ABB REG216 and Advant series, renowned for maturity, stability and easy maintenance, it is widely used in:
Power industry: Circuit breaker control, disconnector operation, protection system trip outputs, alarm circuits in thermal power plants, hydropower plants and substations; especially matched with REG216 generator/transformer protection systems for fault tripping and signal feedback.
Metallurgy industry: Motor start/stop, valve interlocking, equipment status indication for blast furnaces and converters in steel plants, resistant to high temperature and electromagnetic interference in workshops.
Chemical industry: Reactor auxiliary control, material transfer pump/fan switching, general safety alarm circuits, isolating strong electricity and corrosive environments.
Other general applications: Pump/valve control in water treatment plants, safety interlocking for large mining equipment, process switching control in paper production lines.
