Product Details:

SIEMENS 16416-1 is a marshalled termination unit designed for Moore APACS+ and QUADLOG DCS I/O systems, acting as the intermediate signal wiring terminal assembly between field instrument cables and backplane I/O modules. It centrally arranges, distributes and marshals multi-channel analog and discrete field signals, simplifying on-site cable routing, wiring inspection and loop troubleshooting work. The terminal unit adopts industrial reinforced base and reliable screw-type terminal blocks, with stable contact performance and anti-loose structure to avoid poor contact caused by equipment vibration in the cabinet. It is equipped with internal signal routing traces and basic isolation layout, reducing the risk of signal crosstalk between adjacent channels and protecting I/O module front ends from transient voltage surges introduced by field wiring.

It is designed for standard cabinet mounting, easy installation and rearrangement during system expansion, loop modification and module replacement. Each signal terminal has clear marking for channel identification, which greatly shortens the time required for engineers to trace wiring and locate faulty loops during maintenance. The terminal assembly supports matching with various QUADLOG analog and discrete I/O cards, and can be combined to form a complete signal marshalling solution for the control rack. Every spare unit will pass continuity inspection, contact stability test and compatibility verification before shipment to ensure reliable connection with original I/O modules. It is widely stocked as replacement spare parts and wiring accessories for legacy process control DCS systems.

Industry Applications: Applied in petrochemical auxiliary skids, gas flow control systems, boiler closed-loop control rooms and water treatment facilities for conventional analog signal acquisition and valve regulating output.

Note: Confirm SAM combined I/O feature and hardware revision before ordering
