The Opto-Tube is directly connected to the receiver module (ST2). The AOPD receives its 24 VDC power supply via the second M12-cable connection (ST1).
The Opto-Tube itself is connected via the M12 connector (ST) to the AS-i network. Before hand the module has to be programmed with an individual adress (1 - 31).
The emitter module has be wired up separately as described in its mounting and wiring instruction.
notice - Wiring example
The wiring diagram shows an active optoelectronic device (AOPD) (type SLC/SLG 420) with a safety input module AST LC ST-AS (Opto-Tube) connected to the AS-i Safety at Work system.
