Physical Characteristics and Installation
This simulation connector weighs approximately 0.15 kg for lightweight handling. Its dimensions measure 180 mm x 45 mm x 30 mm for direct module attachment. First, disconnect power from the S5 I/O module completely. Then, plug the 6ES5490-7SA21 into the front connector of the target module. Finally, set the slide switches to simulate your desired input states. The connector does not require any external wiring or tools.
Switching Specifications
The 6ES5490-7SA21 features 16 independent slide switches for discrete signal simulation. Each switch connects a 24V DC signal to one input channel when activated. The voltage rating reaches 24V DC maximum for standard PLC inputs. Each channel carries up to 50 mA for reliable signal detection. You can simulate any combination of high and low states easily.
Usage and Compatibility
This simulation connector works with most S5 digital input modules. Use the 6ES5490-7SA21 to test logic sequences without connecting field devices. The connector eliminates the need for temporary wiring during commissioning. You can also use it for operator training and fault simulation. Always remove the connector before restoring normal field wiring.
