Schneider Electric 8030HIM-151 TTL Input Module

Schneider Electric's SY/MAX Class 8030 HIM-151 TTL Input Module is an eight-channel TTL input module for Square D SY/MAX 8030 PLC systems, delivering eight optically isolated inputs that accept TTL-level signals (5 V DC) from sensors or switches. It mounts to the 8030 backplane and reports input states to the SY/MAX controller, enabling reliable digital signaling in industrial environments. Typical applications include reading digital sensors, limit switches, and pushbuttons on manufacturing lines, conveyors, and packaging equipment where 5 V logic devices are used. As part of the 8030 family, the HIM-151 expands discrete I/O for SY/MAX controllers without extra conversion hardware, and is commonly cataloged as 8030HIM-151 (also listed in various suffix variants such as 8030-HIM151) across reseller inventories.
