The Siemens 505-6660B is a rack power supply module designed for the SIMATIC TI‑505 and Series 505 programmable logic controllers. This 505‑6660B selects either 110 V AC or 220 V AC input and outputs +5 V DC and –5 V DC. The 505‑6660B supplies logic power to all modules within a Series 505 chassis. For the PPX:505‑6511 base, the 505‑6660B supports N+1 or 1+1 redundant configurations, ensuring high‑availability operation. Although discontinued, the 505‑6660B remains a crucial spare part for legacy system maintenance.
The Siemens 505‑6108 is an 8‑channel analog input module for SIMATIC 505 systems. The 505‑6108 digitizes voltage (±5V/±10V) or 0–20mA signals with 12‑bit (‑A) or 13‑bit (‑B) resolution. Requiring no external power, the 505‑6108 includes a green Module Good LED. Discontinued, it is directly replaceable by the CTI 2558.
Process control (pressure, flow, temperature)
Factory automation & machine monitoring
Water/wastewater treatment
Power & energy monitoring
HVAC building automation
8 single‑ended inputs, per‑channel voltage/current selectable
12‑bit (A) or 13‑bit (B) resolution
Asynchronous operation, no external 24V needed
1500Vrms optical isolation
Green LED for power/self‑test
Built‑in 250Ω resistor for 0–20mA
Converts analog field signals to digital words for the PLC.
Operates asynchronously – reads pre‑stored buffer values, not live conversion.
Rejects 50/60Hz noise (dual‑slope integration on A‑version).
Isolates inputs optically to protect the CPU.
Detects overrange and sets a dedicated bit in the digital word.
Indicates status via front‑panel LED.
