Siemens 6ES7222-1EF22-0XA0 Output Module

This digital output module provides reliable control for Siemens S7-200 PLC systems. It drives solenoids, contactors, indicator lights, and other 120 VAC field devices. The module’s compact design saves valuable space in control cabinets and expansion chassis.

Output Configuration and Electrical Ratings

The Siemens 6ES7222-1EF22-0XA0 features eight discrete output points, each rated for 120 VAC operation. Each point handles 1.0A of continuous current with a surge rating of 5.0A per point. The total load current per group is 8.0A for the first L1 group and 5.0A for the second L2 group. The module delivers an output delay of 1.0ms from off to on and 2.5ms from on to off. It draws a backplane current of 77mA at 5VDC and 50mA at 24VDC from the system.

Output Protection and Diagnostic Features

The module features short-circuit and overcurrent protection on each output channel. An electronic protection mechanism trips the output in overcurrent conditions. The controller resets tripped outputs automatically after a time delay when the fault clears. LED indicators assist in troubleshooting by showing the current status of each output. These indicators allow operators to verify output states without a programming terminal.

System Integration and Application Use

This module mounts directly onto the S7-200 expansion bus for quick installation. It supports up to seven expansion modules per CPU for flexible system expansion. The module suits machine control, conveyor systems, packaging lines, and material handling applications. Its rapid response times make it suitable for applications requiring quick output switching. The module’s cost-effective design provides reliable control for small to medium discrete applications.
