Product Details:

SIEMENS 16436-1-03 is a fused SDM/CDM marshalled termination assembly designed for QUADLOG and APACS+ DCS systems, matched with SDM and CDM discrete I/O modules for 24VDC field signal transition and loop wiring distribution. It integrates organized screw terminal blocks, built-in fuse protection and internal signal routing traces, centrally arranging multi-channel 24VDC discrete signals from field solenoid valves and limit switches to the corresponding I/O modules. The terminal assembly adopts flame-retardant insulating base and anti-vibration terminal locking structure, which prevents poor contact caused by long-term cabinet vibration. Each channel is equipped with dedicated fuse to provide overcurrent protection, limiting surge current from field wiring and avoiding damage to the matched SDM or CDM module. The internal signal layout reduces adjacent channel crosstalk and electromagnetic coupling interference to maintain stable switching signal transmission.

It adopts standard panel mounting structure for installation inside control cabinets. Each terminal position has clear channel marking, which greatly simplifies cable arrangement, loop inspection and fault locating work during commissioning and maintenance. The -03 suffix stands for this specific hardware revision version, defining fuse rating and channel definition of this termination unit. Every spare unit will pass continuity check, fuse fit test and compatibility verification before shipment to ensure reliable matching with QUADLOG SDM and CDM discrete output modules. It is widely stocked as replacement wiring accessories for legacy 24VDC safety interlock control 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
