Siemens 6ES5451-7LA12 is a SIMATIC S5 digital output module that delivers 32 isolated 24 V DC outputs rated at 0.5 A each for legacy S5 control systems. Designed as a spare part in the SIMATIC S5 family, it supports 24 V DC actuator loads such as solenoids, contactors, and indicator lamps, while providing galvanic isolation between the backplane and the switched loads to minimize interference. The module measures about 195 mm in height, 310 mm in length, and 42 mm in width, with a weight around 0.64 kg, aligning with standard DIN rail or rack mounting footprints used in S5 installations.
