Yudian AI-526 - Commonly Used Modules

6
 A la r m ( AL M ) :
Commonly used as alarm output. Support 1 normally open + normally close relay output (AL1) by installing L1 or
L2 module or 2 normally open relay outputs (AL1+AL2) by installing L5 module.
 Auxiliary output (AUX): In a heating/refrigerating dual output system, module X3, X5, L1, L4, G, W1, W2 can be
installed for the second control output. It can also output alarm by installing L1, L2 or L5 module, or be used for
communicating with computer by installing R module (RS232C interface).
 Communication Interface (COMM): Module S or S4 can be installed in for communicating with computer
(RS485 communication interface), and it can also be used as power supply for external sensor when equipped
with a voltage output module (except for front panel D2 size).
