It supports two digital input supply models—B for 24 VDC and D for 120 VAC—allowing you to match the card to field wiring. Addressing is configured via four dip switches (SB3) to create a 4‑bit card address from 0 to 15; A0 is the least significant bit, and when a switch is ON it contributes 0 to the address, while OFF contributes 1, 2, 4, or 8 (A0–A3). This scheme lets you install multiple CA403 cards in the same rack with unique addresses. The combination of analog I\/O and digital I\/O makes the CA403‑3 suitable for mixed‑signal monitoring and control in industrial automation, enabling 3 channels of analog sensing, 2 channels of analog actuation, digital input signals, and relay‑driven switching via Form C outputs. The unit’s compact PC‑board form factor is designed for modular expansion in control cabinets, and it weighs about 2.0 lb. Together with the +10 V fixed output, the CA403‑3 supports straightforward integration of sensor networks and control signals within Saftronics’ automation ecosystem.\u003c\/p\u003e\u003c\/div\u003e","brand":"Saftronics","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46284096766186,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-022.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/saftronics-ca403-3-multiple-input-output-card","provider":"GTG Hardware","version":"1.0","type":"link"}
