6ES5451-4UA11 - Digital Output Module - SIEMENS
This digital output module 6ES5451-4UA11 and SIEMENS is a module with 32 digital outputs for the SIMATIC 135U/155U range.
SIMATIC S5, DIGITAL OUTPUT 451-4 POTENTIAL INSULATED COMPACT DESIGN 32 OUTPUTS DC 24V / 0.5A
This SIEMENS module is at your disposal to replace your defective equipment and has a guarantee.
The digital output modules convert the internal signal levels of the programmable controllers into the binary signal levels required externally by the process.
Digital output modules with 32, 16 and 8 outputs are available with a range of out put voltages and also with relay contact outputs. The modules require either one or two slots.
Front connectors are used for terminating the signal cables. Modules and front connectors may be inserted and removed under power.
Green LEDs indicate the sig nal status of the outputs. In DC output modules, red LEDs indicate short circuits in the signal leads. The signal out put H is set to "1" if an over current or short circuit is detected in an output. Up to 16 signal outputs can be connected in parallel. In AC out put modules, red LEDs indicate when a fuse has blown.
Adhesive labels are supplied to identify modules and front connectors.
Enable input
The output of signals can be suppressed by an enable input F. This function can be deactivated by removing a jumper on the module.
Siemens is an international group of German origin specializing in high technology and present in the sectors of industry, energy and health. It was founded in 1847 by Werner von Siemens.
