16 Isolated Relay Outputs Wide Voltage Range (5-230V AC) High Current Rating (5A) SIMATIC S7-400 Compatibility Suitable for Higher Power Loads

Product description

The Siemens 6ES7422-1HH00-0AA0 is a digital output module within the SIMATIC S7-400 series. This SM 422 module is equipped with 16 isolated relay outputs, capable of switching a wide voltage range from 5V to 230V AC, with a significant current capacity of 5A per output. The use of relay outputs provides robust isolation and the ability to switch higher power AC loads.

This module is ideal for applications requiring the switching of diverse AC loads, including motor control, high-power solenoid valves, and general AC power distribution. The 5A rating makes it suitable for more demanding applications than standard transistor outputs.

Stanlo Automation, a veteran-owned surplus parts distributor, is your trusted source for the Siemens 6ES7422-1HH00-0AA0. We provide quality industrial automation components to meet your project needs.
