HD2000
HD2000 series safety relays constitute a primary component within safety control circuits, receiving safety control signals as input and outputting relay switching signals which are integrated into the equipment's control circuitry. They accept wide-range voltage (16–35) VDC control switching signals, employing triple redundancy technology, automatic protection technology, and contact welding protection to achieve safe and reliable isolation circuits.
Product Advantage
1. Triple redundancy protection
2. Compatible with DIN35 rail and baseplate mounting
3. Supports wide voltage control power supply and non- polarity input
4. Relay output switch channel with limited capacity protection design
5. Compact, space-saving housing
6. Supports top port and baseplate control power input
7. Plug-and-play terminals with hot-swappable capability for easy installation and maintenance
8. Multiple options available, including normally open (NO), normally closed (NC), and a combination of NO and NC contacts
9. The product meets the requirements of IEC61508 standard and has obtained SIL3 certification from the authoritative organization TUV
Technical Parameters

Product Uses
1.Triple redundant 5 Amp high power contacts, 2ms filtering for SIS pointing diagnostic signals
2.Wide power input range: voltage input range (16-35) V, and can support bipolar input, output Max.250VAC

Q: What safety integrity level can the safety relay achieve? Does it comply with international standards?
A: Safety relays achieve SIL2/SIL3 per IEC61508/ISO13849-1 through positively guided contacts (EN50205), ensuring safety functions remain intact even if contacts weld.
Q: How complex is installation and commissioning? Can downtime be minimized?
A: HD2000 safety relays minimize downtime through plug-and-play design. Self-evaluating types require zero programming—typical commissioning under 2 hours.
