Siemens 6ES5454-7LA11 Digital Output Module

Product Overview

The Siemens 6ES5454-7LA11 is a SIMATIC S5 454-series digital output module with 16 outputs for 24 V DC field circuits. Each output is rated at 2 A, giving the controller a way to switch multiple discrete loads from one module. The outputs are arranged in four groups of four, with optocoupler-based galvanic isolation. Siemens also specifies electronic short-circuit protection. This combination of output capacity, current rating and grouped isolation makes the module suited to S5-based control tasks involving devices such as solenoid valves, contactors and indicator lamps.
