This high-density module features eight 24 VDC sinking or sourcing discrete inputs and eight isolated normally-open (NO) relay outputs housed within a single slot form factor. The module interfaces directly with standard industrial input sensors, switches, and field actuation components, processing steady-state digital logic data while providing dynamic electrical isolation between the backplane bus logic and field circuits.\u003c\/p\u003e\n\n\u003ch3\u003eCore Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e IC694MDR390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e GE Fanuc (Emerson)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Mixed Discrete Input\/Output Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e PACSystems RX3i\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.36 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 34 mm x 145 mm x 140 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inputs:\u003c\/strong\u003e 8 points (1 group with shared common)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e -30 to +32 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Current:\u003c\/strong\u003e 7.5 mA typical at 24 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Outputs:\u003c\/strong\u003e 8 points (normally open relay, 2 groups of 4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage Range:\u003c\/strong\u003e 5–30 VDC or 5–250 VAC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Current Rating:\u003c\/strong\u003e 2 A maximum per point; 4 A maximum per common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInrush Rating:\u003c\/strong\u003e 5.0 A maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic Isolation:\u003c\/strong\u003e 1500 Vrms field-to-logic; 500 Vrms between output groups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Response Time:\u003c\/strong\u003e 7 ms typical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Response Time:\u003c\/strong\u003e ≤ 15 ms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Power Consumption:\u003c\/strong\u003e 80 mA @ 5 VDC (logic); 70 mA @ 24 VDC (relay)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0 to +60 deg C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFunctional Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCombines discrete DC sensing and mechanical relay actuation into a compact single backplane slot allocation.\u003c\/li\u003e\n\u003cli\u003eSupports bidirectional logic configuration, operating as either a sinking or sourcing input layout via the user-common connection.\u003c\/li\u003e\n\u003cli\u003eIntegrates firmware-driven I\/O data scaling to accommodate high-velocity backplane bus communication across the RX3i chassis.\u003c\/li\u003e\n\u003cli\u003eProvides individual optical and galvanic status barriers to shield vulnerable core processor architectures from electromagnetic line noise.\u003c\/li\u003e\n\u003cli\u003eEquipped with 16 dedicated front-panel LED indicators displaying discrete real-time logic states for each independent input and output point.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInsert the module into any available I\/O slot of an RX3i Universal Backplane.\u003c\/li\u003e\n\u003cli\u003eThis component does not support hot-swap capabilities; the entire host RX3i backplane must be de-energized prior to structural insertion or physical module removal.\u003c\/li\u003e\n\u003cli\u003eExternal AC or DC power sources must be wired independently by the system installer to drive all connected field equipment, as the module contains no internal fusing.\u003c\/li\u003e\n\u003cli\u003eMaintain structured separation between low-voltage DC input signal runs and high-voltage AC inductive load wiring inside the routing conduits to maintain optimal signal integrity.\u003c\/li\u003e\n\u003cli\u003eEnsure field terminals are securely locked down to minimize electrical arc resistance and noise cross-talk over high-density deployments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes the IC694MDR390 support hot-swapping or live insertion?\u003c\/strong\u003e\u003cbr\u003eNo. The module does not support insertion into or removal from an RX3i Universal Backplane while the system is under power.
