FAQ What is the difference between the EMD-SL-PTC and its successor, the EMD-FL-PTC-280?The EMD-FL-PTC-280 is a more modern design, featuring a narrower housing (only 17.5 mm wide), enhanced diagnostics via LEDs, and a wider temperature range. However, the core function of monitoring PTC thermistors is identical. Can I use a different power supply module with the EMD-SL-PTC base unit?Yes, the EMD-SL-PTC base is compatible with various plug-in power modules from the Phoenix Contact EMD-SL-PS… series. This allows you to adapt the unit for different supply voltages, such as 24V DC or 120V AC, simply by swapping the module. How do I correctly connect PTC thermistors to this relay and what does ‘Max. 6 PTCs’ mean?The PTC sensors must be connected in series across terminals T1 and T2. The ‘Max. 6 PTCs’ specification means that the total cold resistance of all series-connected thermistors should not exceed the standard limit, which is typically under 1.5 kOhm.
