SIEMENS Power supplies IM 360/361/365 interface modules
IM 360/361/365 interface modules
Overview
- For connecting mounting racks in multi-tier SIMATIC S7-300 configurations
- IM 365: For design of central controller and max. 1 expansion unit.
Limited use of modules in the expansion unit (e.g. no CPs or FMs) - IM 360/IM 361: For design of central controller and max. 3 expansion units.
No limitation in selection of modules in the expansion unit
IM 360/361/365 interface modules Application
IM 360/IM 361 and IM 365 modules support a multitier configuration of the S7-300 automation system (CPU 313C, CPU 314 or later), consisting of a central controller (CC)and up to three expansion racks (ERs).
The individual racks are interconnected via the interface modules.
- IM 365:
Central controller and 1 expansion rack each with max. 8 modules; Distance: 1 m - IM 360/IM 361:
Central controller and max. 3 expansion racks each with max. 8 modules; Distance between two adjacent racks: 4 cm to 10 m
IM 360/361/365 interface modules Design
General features
All interfaces have the following common features:
- Compact configuration:
The rugged plastics housing contains the interfaces for the connecting cables. - Simple mounting:
The interface modules are mounted on the DIN rail (slot 3) and connected to the I/O modules via a bus connector just like any other module. - Problem-free configuration:
The interface modules are self-configuring. Address assignment is not required. - Status and fault LEDs
IM 365
The IM 365 is the low-cost expansion for an ER. It contains the following features:
- One of the two IM 365 modules is inserted in the CC, the other into the ER. The modules are connected by a fixed cable 1 m in length.
- Limited use of modules:
The ER is not connected to the C bus (communication bus). Therefore, no C bus nodes (e.g., CPs and FMs, see configuring aids) may be inserted into the ER. - No separate power supply:
The modules in the ER are powered by the CPU power supply.
IM 360/IM 361
IM 360 and IM 361 are the ideal solution for comprehensive expansions. They contain the following features:
- IM 360 plugs into CC
- IM 361 plugs into each ER
- Separate power supply
Each IM 361 requires an external 24 V DC power supply. This then powers all modules of the respective ER. A PS 307 load power supply can be connected using a power connector. - No module selection restrictions:
All S7-300 modules can be used in the ER.
