Memory-type Temperature Controllers

I. Overview
LU-923M delay relay is a high-performance, high-reliability intelligent time alarm instrument adopting a brand-new design concept.
Main features:
It adopts an advanced ARM processor, featuring fast processing speed, simple interface components, high timing accuracy, and high reliability and stability.
1 high-precision timing clock; 4 groups of alarm registers can be freely combined, providing rich time alarm outputs that can be freely defined to any physical output interface.
It has an external reset signal event input (dry contact). The timing reset operation can also be started via the panel key.
Dual-row 4-digit digital tube display, human-machine interaction operation, simple and easy to use.
Plug-and-play modular structure and rich output specifications meet various application requirements.
It adopts the standard MODBUS communication protocol, with strong versatility and high reliability.
Strong anti-interference performance, passing the industrial level-3 electromagnetic compatibility test requirements.
