The 6ED1052-2MD00-0BA5: Four relay outputs: 10 A resistive maximum, 3 A inductive per channel. External fusing is required – no internal short-circuit protection.
Power reserve holds program and real-time clock for 80 h without external supply.
Height 90 mm, depth 55 mm. Leaves room for expansion modules on the right side – the LOGO! bus can chain additional digital/analog modules.
Rated for 0 °C to 55 °C ambient operation.
No, these are different product categories. The 6ED1052 is a stand-alone logic module with integrated CPU and I/O, while the 6ES7222 is a SIMATIC S7-200 output module requiring a base controller. They are not designed to be interchangeable.
No – external fusing is required for each output circuit.
