Safety relays

Quanta series: from standard relays to a small-PLC replacement

All models support single or dual channel with automatic or manual reset. The whole range features input debouncing, and inputs stay stable over runs up to 300 m.

2nd-gen patented

Quanta · CN series

Second-generation patented safety relay with positive-guided outputs and DIP-switch configurability for different safety functions; redundant supply terminals simplify 24 V DC distribution.

  • Multi-function input via function DIP switches
  • Redundant supply terminals — 33% more efficient 24 V DC wiring
  • Auto / manual reset lever, independent per-channel LEDs
  • Dual-channel monitoring circuit; input filtering for 300 m runs
CNSC31SCNUG31SCNTC22S-99CNTC31S-99
Standard

Quanta · DN series

First-generation standard safety relay with conventional positive-guided output — the most widely applied and most cost-effective baseline model.

  • Conventional positive-guided output
  • Redundant supply terminals — 33% more efficient 24 V DC wiring
  • Auto / manual reset lever, independent per-channel LEDs
  • Dual-channel monitoring circuit; input filtering for 300 m runs
DNSC31SDNSD31SDNTC22S-99DNTC31S-99
Configurable

Quanta · HN series

High-performance configurable safety relay — one unit does the work of two conventional relays, and three units linked together can replace a small safety PLC.

  • 4 configurable fail-safe inputs (4SI)
  • 2 configurable fail-safe NO safety relay outputs (2SO)
  • 2 self-monitored safety sources (2SS) and 2 configurable general inputs (2DI)
  • 2-digit 8-segment display; Type-C USB and NFC configuration
HNUG20S-99HNUG20P-99
Extension

Extension modules

For output extension of safety relays, safety PLC expansion and safety coupling — including SIL-rated industries such as petrochemical SIS.

  • Standard structure, or power and dual-channel synchronous structure

Safety switches & interlocks

Four product lines, chosen by guard type and cycle rate

Non-contact switches suit high-frequency operation, washdown and easy-cleaning areas; solenoid interlocks suit guards that must stay locked until the machine has stopped; mechanical interlocks suit conventional guards where cost matters most.

Guardian EN series — non-contact safety switch

Coded magnetic and RFID non-contact safety switches for monitoring safety doors and windows. Up to 30 units can be daisy-chained without degrading the safety level.

  • IP69K across the range; -25°C to 90°C (high-temperature range) or -25°C to 70°C (active range)
  • Outputs up to 2+2: two safety contact outputs plus two PNP transistor outputs
  • Compact, 360° mounting; high-brightness LEDs give rich diagnostics

Typical applications: food packaging, 3C semiconductor, injection moulding, pharmaceutical equipment, glass machinery.

Coding: C = passive magnetic, M = active magnetic, F = active RFID, MT / FT = cascaded-input variants; 30 = 3NO, 11 = 1NO+1NC, 20 = 2PNP, 22 = 2PNP+2NO; L = with LED; 3M = 3 m cable, M12-8 = M12 8-pin plug.

Bodyguard T3 (Oxon-T3) — solenoid interlock

Full-size solenoid safety interlock with 1,000,000 mechanical operations and 2000 N holding force, for heavy guards and fencing.

  • Electrical and mechanical interlock signals together
  • Stainless steel and engineering plastic hybrid structure, all-metal head
  • Rotatable head (4 × 90°); optional emergency escape device

Coding: A = mechanically locked / solenoid released; G = solenoid locked / released on power loss.

Bodyguard M1 (Guard-M1) — compact solenoid interlock

Compact solenoid interlock, smaller than the T3, for space-restricted machine guards.

  • Very small footprint, electrical + mechanical interlock signals

  • Fencing: ISO 14120 (1600 J impact resistance)

Two points to check when selecting

  • Match the curtain type to the risk assessment: GM1 is a type 2 light curtain while GM2 / GM3 are type 4. They suit different applications — choose according to your ISO 13849 risk assessment.
  • UL coverage is partial: not every model is UL certified (certain relay models, DNB41S and others). Verify per model before shipping to North America.
Specifications on this page come from the manufacturer's 2026 product catalogue. Before tendering or public promotion, please obtain certificate copies and current datasheets from the manufacturer for verification.
Manufacturer service capability

Safety assessment and upgrade — turnkey

Duoen Technology provides professional safety assessment and retrofit services that help customers quickly identify mechanical safety risks in production equipment.

Scope of service

  • Estimate the probability and severity of accident injury
  • Stop accidents at the source and avoid the downstream business impact
  • Professional machine-safety risk assessment reports issued by TUV- and CMRE-certified assessors
  • Keep the existing production line intact while establishing new safety function circuits and human-machine safeguarding
  • Design based on third-party assessment and site survey results, isolating each risk point with safety devices
  • Short downtime and fast implementation; standardised installation, commissioning and training with easy maintenance

Why a safety assessment pays off

In the manufacturer's analysis of mechanical risk sources, incorrect specifications account for 44%, adjustments after trial runs 20%, operation and maintenance issues 15%, design issues 15% and installation issues 6%. The overwhelming majority of risk originates in early design and parameter selection rather than the machine itself — exactly what an assessment can catch in advance.
