In a chemical plant, it reliably controls actuator banks and process valves. Its fast switching capability (up to 100 Hz with resistive load) makes it suitable for sorting lines and packaging machinery. The isolation between groups of 8 channels prevents cross-talk in redundant control schemes, enhancing system safety.\u003c\/p\u003e\u003ch2\u003eCompatibility and Integration\u003c\/h2\u003e\u003cp\u003eThe Siemens 6ES7422-1BH11-0AA0 integrates directly into standard SIMATIC S7-400 racks via the backplane bus. It is compatible with CPUs such as the 414-2, 416-2, and 417-4. The module draws up to 160 mA from the 5 V DC backplane bus and requires an external 24 V DC load supply. For redundant load control, two outputs from the same group can be paralleled.\u003c\/p\u003e\u003ch2\u003eSelection Guide and Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering the Siemens 6ES7422-1BH11-0AA0, verify that your S7-400 rack has an available slot and that your system power supply can accommodate the additional 160 mA backplane current plus load requirements. The front connector is ordered separately. This module is available from PLC Source PRO, your trusted supplier for industrial automation spares.
