Description:

• A paired cable for a floating-ground-powered intrinsically sage signal circuit (such as EX IA supply isolation amplifiers) and a surge protection plug for base element VSPC BASE 1CL PW FG EX with dual protective circuits Temperature-controlled varistors operate as a cross-protection between the active lines in a protective switched power supply.
• The common mode voltage is coarsely protected from the earth.
• Temperature monitoring in conjunction with an optical defect signal.
• Signal circuits driven by floating-ground protection include two-stage protection switches with decoupling resistors and coarse and fine protection between the signal wires.
• The rated voltage and switching type are used to mechanically identify the plug from the base element.
• A counter-profile and coding pin-equipped protected plug for the base element.
• Optical identification of the protected plug according to voltage level and protected switching type.
• The plug can be marked.
