Siemens SIMATIC S7-200 SMART Relay Output Module About

The Siemens 6ES7288-2DR08-0AA0 is an active, compact SIMATIC S7-200 SMART digital output expansion module (SM DR08). It is engineered to scale up the payload capacity of small-to-medium industrial automation networks. This module integrates eight digital relay outputs, each supporting a substantial thermal continuous current rating of 2A per channel.Featuring dry-contact mechanics divided into two isolated circuit groups, it acts as a reliable electrical isolation layer between core logic and high-energy machinery. It safely drives mixed-voltage field applications, switching loads from 530V DC or up to 250V AC for components like contactors, lamps, and solenoid valves. Housed in a dense, IP20-protected shell designed for standard DIN rail installations, the expansion block operates with a low typical coil current of 80mA. It includes individual front-facing LEDs for real-time channel status verification.
