Operating on a nominal 24 VDC control voltage, the pre-wired hardware assembly manages discrete safety signals to actuate final elements in safety-instrumented loops. Integrated galvanic isolation separates control logic from field-side electrical noise, maintaining signal integrity without introducing backplane cross-talk or logic interference.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eVR-H 4135\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHIMA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e51 x 127 x 51 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003eStandard Industrial Range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eStandard Loop Draw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eMonitors safety circuits and triggers shutdowns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHIMatrix, HIQuad\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign Assembly\u003c\/td\u003e\n\u003ctd\u003ePre-wired compact module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompliance\u003c\/td\u003e\n\u003ctd\u003eCE, FCC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eSIL3 Certification \u0026amp; Fail-Safe State Execution\u003c\/h3\u003e\n\u003cp\u003eCertified to strict SIL3 safety requirements, the hardware incorporates internal redundant switching paths to enforce deterministic fail-safe state execution during signal loss or power disruption. Complete galvanic isolation decouples field-side switching transients from sensitive safety logic circuits, suppressing common-mode electrical noise. When a trip threshold is breached or control loop power drops below operational limits, internal mechanical springs force the contact pathways into a de-energized fail-safe open position, isolating downstream equipment within millisecond timeframes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the pre-wired design influence installation and circuit integrity?\u003c\/p\u003e\n\u003cp\u003eA: Factory pre-wiring establishes standardized contact terminations that minimize field-side wiring errors while preserving low-impedance connection points for critical trip circuits.\u003c\/p\u003e\n\u003cp\u003eQ: What mechanisms prevent field electrical surges from affecting host HIMatrix or HIQuad controllers?\u003c\/p\u003e\n\u003cp\u003eA: Integrated galvanic isolation establishes a physical barrier that blocks voltage surges, ground loops, and inductive feedback from propagating back to the safety processor bus.\u003c\/p\u003e\n\u003cp\u003eQ: What fail-safe position do the output contacts assume during a loss of 24 VDC control power?\u003c\/p\u003e\n\u003cp\u003eA: Upon power interruption, the internal armature immediately transitions the switching contacts into a de-energized open state to trigger an emergency shutdown sequence.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the module directly into standard enclosure chassis or DIN rail assemblies inside IP20-rated control cabinets.

Route 24 VDC safety signal wiring in dedicated grounded cable conduits separated from high-voltage AC motor drives and switching power lines to prevent inductive noise coupling. Maintain clear physical spacing around the module perimeter to allow unimpeded passive convective cooling during standard operation.\u003c\/p\u003e","brand":"HIMA","offers":[{"title":"Default Title","offer_id":43823299035235,"sku":"VR-H 4135","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/136_e28724e8-09e9-49f5-bb00-fe1245b00b60.jpg?v=1762499358","url":"https:\/\/www.autocontrolglobal.com\/products\/hima-vr-h-4135-himatrix-hiquad-safety-relay-module","provider":"AutoControl Global","version":"1.0","type":"link"}
