| Long specification | Surge protection plug for base element VSPC BASE 1CL PW FG EX with dual protective circuits, for intrinsically sage power supply and a paired cable for floating-ground powered intrinsically sage signal circuit (forexample, EX ia supply isolation amplifiers) protective switched power supply: temperature controlled varistors as a cross-protection between the active lines. Coarse protection of the common mode voltage to earth. Optical defect signal coupled with the temperature monitoring. Protective circuits, floating-ground driven signal circuits: two-stage protection switches consisting of coarse and fine protection between the signal wires as well as decoupling resistors. Mechanical identification of the plug to the base element according to the switching type and rated voltage. Protected plug with coding pin and counter-profile for the base element. Optical identification of the protected plug based on the type of protected switching and the voltage level. It is possible to mark the plug. |
| Short specification | Surge protection plug for base element VSPC BASE 1CL PW FG EX with dual protective circuits, for 24 V power supply and a paired cable for floating-ground powered signal circuit. Suitable for protecting intrinsically safe Ex ia circuits. |
