INTRODUCTION

The ET-7245/PET-7245 provides 16 source-type digital output channels. It features optical isolation for 3750 VDC of transient overvoltage protection and doesn’t have channel-to-channel isolation. The power-on value and safe value of digital output channelare programmable. In some industrial applications, the user can connect the output channel of ET-7245/PET-7245 to the RM series relay module to switch inductive loads.
