Summary
ZDZ1 multifunctional gauge combination module is composed of double-pointer speed gaug
ammeter, state indicator light, emergency brake button, signal transmission cable. Installed in
console, it is an important set, showing train operating parameters, equipment operation state, and ot
information. Depending on the combined module structure, it is endowed with the following a
convenient installation, visual display, integral beatification, good reliability.  

Function
1. Measure and display the instant speed and limited speed of running locomotive.
2. Measure important operation parameters of locomotive. (See appendix)
3. Display the operation state of equipment in locomotive. (See appendix)
4. Electric locomotive have emergency brake button, while diesel locomotive don't.  

Technical Parameter of Gauge Module
The technical parameter of gauge module is composed of three separate technical par
double-pointer speed gauge, slot-type ammeter, and state indicator.
