Product Details Introduction

Siemens 505-6660 power module

Belonging to the Siemens SIMATIC 505 (formerly TI 505) series PLC system, it provides * *+5V DC and -5V DC dual stable power supply * * for the CPU, I/O modules, and backplane bus in the rack.

Input supports a wide voltage range: 85-132 VAC or 170-264 VAC (nominal 110/220 VAC), compatible with 47-63 Hz industrial power grids.

Core output parameters:+5V DC 11A (55W), -5V DC 0.75A (3.75W), with a total output power of approximately 58.75W, meeting the system's full configuration requirements.

Built in 3.0A/250V slow melting fuse (3AG specification), with input overcurrent and surge suppression capabilities, enhancing power supply safety.

Adopting a backplane installation method, it can be directly connected to the 505 system rack without the need for additional external fixation and is compatible with models of the 505-6660A series.

The maximum input surge current is 50A (continuous for 100ms), and it adapts to the impact of the power grid at the moment of startup to avoid the influence of power grid fluctuations on startup.

The electrical characteristics comply with industrial standards such as IEC 1131-2, adapt to complex on-site environments such as workshop dust and temperature changes, and have strong stability.

Supporting system redundancy and hot standby configuration, it can be used in conjunction with 505 series redundant systems to enhance power continuity in critical production scenarios.

Wiring specifications: It is recommended to use 14AWG copper wire for the input power cord, with a stripping length of approximately 10mm, to ensure a secure connection and proper grounding treatment.

The product has been discontinued, and the current market mainly consists of second-hand, refurbished, and original spare parts, suitable for the maintenance, replacement, and upgrading of old 505 systems.

In summary, Siemens 505-6660 is an industrial PLC power module with wide voltage input and dual stable output. With high compatibility and strong reliability, it has become a core spare part for power supply and maintenance of old SIMATIC 505 control systems, effectively ensuring long-term stable operation of the system.
