Hello Willies; In this discussion (from another forum) you will find assumptions on the calculation of heat dissipation in relation to Power Loss (inWatts). http://www.plctalk.net/qanda/showthread.php?t=40030 This last information you can find in the technical data of CPUs and I/O modules of all PLC manufacturers. For example, look at the attachment, which shows the typical Power Loss for a CPU 312C (From the Technical data manual for S7-300 CPUs). Here are manauls for S7 CPUs and I/O modules that should give you the required information. SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Automation System S7-400 CPU Specifications SIMATIC S7-300 S7-300 Automation System Module Data SIMATIC S7-400 S7-400 Automation System Module Data Hope this helps, Daniel Chartier |
