Model Selection Tips

• 5463-581 = 8-channel isolated 4–20 mA input + relay output
• For 0–5V analog inputs, use 5463-582
• For 0–10V analog inputs, use 5463-583
• For analog outputs, use 5463-786 (8-channel analog output)
• For discrete outputs only, use 5463-873
• Verify transmitter signal type (4–20 mA vs. voltage) before ordering
• Confirm RS-485 network master module compatibility
• Check relay contact voltage/current ratings against load requirements
