Loop Control electronic board
ZUC 40 is a board that analyzes the current loop of the general security systems. ZUC 40 electronic card is used in order to control the devices from a cut off detection (PERISTOP®, PERIFENCE, PERISAS, PERICOIL). It is protected against electromagnetic interference and provides dry contact information and IP or RS485 “MODBUS” protocol.
Monitoring two independent loops
Detecting cuts off and short circuit
Analysis of leakage current - Protection against sabotage
Immunity to electromagnetic interference
Interfacing with systems monitoring via dry contact / RS485 / IP Ethernet
Ground cabinet version 2 or 4 zones
Rack Version in centralized bay
The electronic card ZUC 40 is an analysis module which is used to control systems by using the technique of controlling a loop current.
ZUC 40 is the heart of perimeter protection system, its electronic monitor’s measures the integrity of a sensor wire connected between its two input terminals. It analyzes the measurements by statistical treatment and generates alarms or faults if necessary.
ZUC 40 electronic card is protected against power surge, it has a high immunity to interference and algorithm analysis was designed to provide security against sabotage.
ZUC40 analysis module is used for monitoring loop, performs two types of measurements on the wire detector:
It is thus possible to control within very precise limits, programmable by PC, the values of the electrical impedance of the loop and the value of leakage current between the loop and the ground and / or armoring protection.
Security against sabotage
The accuracy and sensitivity of the measurement technique makes a decommissioning of the detection system by a destroyer, without causing an alarm, extremely long and difficult.
High noise immunity
Because of the long length of the loops, short interference or noise spikes induced voltages can be captured in a highly disturbed electric environment. They are then processed by the evaluation device to be discriminated and removed.
Protection against voltage surges
The spikes of high energy (example due to indirect exposure to a lightning strike) are limited by the use of a daughter card to protect against lightning. Galvanic insulation between the different cards prevents any transfer of the destructive effect.
