3.9
Intrinsically safe signal connections (option)
Only valid for the GMS815P-PS-3G with intrinsically safe signal connections.
3.9.1
Technical layout of the intrinsically safe signal connections
When desired, some of the analog outputs, digital inputs and digital outputs can be real-
ized as intrinsically safe signal connections. Additional modules are fitted for this purpose
(Zener barriers). All intrinsically safe connections can be configured according to customer
requirements.
