Note: Max Reset frequency is 150Hz for AC models. **Notes:** 1. All modules are supplied with critical components exposed. If the module is being used in an environment other than specified, the user must take precautions to package the module to provide adequate protection. 2. For proper mechanical support, all module pins should be soldered to the PC-board. 3. To prevent heat damage to components, module face should be 10-20mm minimum away from PC-board when flow soldered.
