Yudian AI-516 - 1.3.2 Commonly used modules

6
installing W1 or W2 module can implement TRIAC no contact switch output.
●
Alarm (ALM): Support 1 normally open + normally close relay output (AL1) by installing L0 or
L2 module or 2 normally open relay outputs (AL1+AL2) by installing L3 module.
●
Auxiliary output (AUX): Support 1 normally open + normally close relay output (AL1) by
installing L0 or L2 module or 2 normally open relay outputs (AL1+AL2) by installing L3 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).
