Introduction

Moxa’s ioPAC 8500 Series 85M Modules can be installed in both ioPAC 8500 and ioPAC 8600 Series devices. Modules are available with DI/Os, AIs, Fast AIs, and serial interfaces, giving users a wide variety of options to choose from and allowing them to select the I/O combination that best fits their target application. All 85M modules are designed for railway industry applications, and as such, are compliant with EN 50121-3-2, EN 50121-4, and a portion of the EN 50155 specifications. In addition, these modules all support a wide operating temperature range of -40 to 75°C for reliable operation even in harsh environments.
