750-103产品概述
Features
Positive-guided relay outputs: – 2 safety contacts (N/O), instantaneous
1 semiconductor output
Connection options for: – E-STOP pushbuttons, – Safety gate limit switches, – Start buttons, – Light grids and safety switches with detection of shorts across contacts
A connector can be used to connect 1 PNOZsigma contact expansion module
Operating modes can be set via rotary switch
LED indicator for: – Supply voltage; – Input status, channel 1; – Input status, channel 2; – Switch status channel 1⁄2; – Start circuit; – Error
Plug-in connection terminals (either spring-loaded terminal or screw terminal)
The circuit is redundant with built-in self-monitoring.
The safety function remains effective in the case of a component failure.
The correct opening and closing of the safety function relays is tested automatically in each on-off cycle.
