ABB 216VC62A HESG324442R13/B – Compact Industrial Safety Relay for Critical Control Applications

You might notice that not all safety relays handle dual-channel monitoring with the same reliability—this one does. The ABB 216VC62A (HESG324442R13/B) is a compact, plug-in safety relay designed to monitor emergency stops, safety gates, and two-hand control systems in machinery where functional safety can’t be compromised. From my experience, it’s typically found in packaging lines, automated assembly stations, and material handling systems where space is tight but redundancy matters.

Key Features

• Dual-channel safety monitoring – Supports category 4 compliance per ISO 13849-1, making it suitable for high-risk applications.
• Plug-in design with test button – One thing I appreciate is how quickly you can replace or verify operation without rewiring the entire cabinet.
• LED status indication – Clear visual feedback on power, coil activation, and fault conditions reduces troubleshooting time.
• For use with ABB’s S-series base sockets – Typically paired with HESG324441R1xxx series bases, offering flexibility in panel layout.
• Low power consumption – Draws less than 5W, which helps keep thermal load down in densely packed control panels.

Technical Specifications

Application Fields

This relay tends to show up in environments where machine safety circuits must meet PL e or SIL 2 standards without integrating full safety PLCs. In many cases, we’ve seen it used in robotic workcells with light-to-medium guarding requirements, conveyor interlock systems, and automated door controls in industrial ovens. It’s also common in retrofits where legacy equipment needs updated safety compliance without a complete control overhaul.

Advantages & Value

Procurement teams often favor this model because it balances cost and compliance. While not programmable, its simplicity means fewer points of failure—and faster approvals during safety audits. Compatibility with standard DIN bases makes spare stocking easier across multiple sites. And since ABB maintains long-term availability for these components, you’re less likely to face obsolescence issues down the road.

Installation & Maintenance

Mounting is straightforward—just clip it onto a TS35 rail using a compatible base. Make sure the control cabinet meets IP54 standards if deployed in dusty or humid areas. Ventilation should allow airflow around the unit, especially when operating near max ambient temperature. Wire connections are screw-terminal type; torque to 0.5–0.6 Nm to prevent loosening over time. For maintenance, visually inspect LEDs quarterly, clean dust buildup annually, and consider replacing every 7–10 years depending on cycle count. Firmware updates aren’t applicable here—it’s a hardwired device—but always check for mechanical wear on contacts if switching high loads frequently.

Quality & Certifications

It appears that ABB has maintained consistent certification alignment across this product line. The 216VC62A carries CE, UL Listed (File No. E101387), and complies with RoHS directives. It meets EN 60947-5-1 and EN ISO 13849-1 standards for safety-related parts of control systems. Units come with a standard 365-day warranty covering defects in materials and workmanship.

Order Placement & Delivery

Most orders ship within one week if in stock. For out-of-stock units, lead time won’t exceed four weeks. We require 50% advance payment to confirm the order, with the remaining 50% due before shipment. All deliveries are handled via FedEx, UPS, or DHL—your choice based on urgency and regional coverage.
