DC System Insulation Monitoring Device : AIM-D100-CAD,AIM-D200-CAI, AIM-D500-CA

■ Insulation resistance monitoring. The product can monitor the insulation resistance of the

DC system to the ground, and can monitor the insulation resistance of the positive pole to the

ground and the negative pole to the ground of the DC system respectively.

■ Voltage monitoring. The product can monitor the voltage between the positive and

negative poles of the DC system, the voltage between the positive pole and the ground, and the

voltage between the negative pole and the ground.

■ LED indication. The product panel has operation, communication, fault, prewarning and

alarm LED indicators to display the product status.

■ LCD display. The product can display parameter with 128*64 dot LCD.

■ Prewarning and alarm. The product has two sets of independently adjustable set values, which can set prewarning values and alarm values. When the insulation resistance is lower than

the set value, the product will send out prewarning and alarm signals.

■ Voltage alarm. The product can monitor the voltage fluctuation of the DC system and

send out an alarm signal in time when overvoltage or undervoltage occurs.

■ PEKE break alarm function. The product can monitor the connection status of PE, KE and the grounding terminal. When any connection line is disconnected from the grounding terminal, the

product will send out an alarm signal.

■ Insulation location function. When the DC system voltage exceeds 50V, you can use the "Insulation location" submenu to view the voltage of positive pole to ground and negative pole to ground, resistance of positive pole to ground and negative pole to ground to evaluate the fault location.

■ Digital Input function. The product has one DI, connected to an external button switch. The device

will self-test with short press (<2s, same below), it will reset with long press (>2s, same below), and it will switch status between the "Monitoring" and "Stop Monitoring" with continuous long

press (>5s, same below).

■ Digital Output function. The product has two DO, which correspond to insulation prewarning and

alarm by default, and they can be modified to overvoltage, undervoltage, reverse connection and

other faults. The DO can choose mode of normally open (N/O, same below) or normally closed

(N/C, same below).

■ Sequence of Events (SOE) function. The product can record 50 SOE with fault type, fault value

and fault time, which is convenient for staff to troubleshoot.

■ Remote communication function. The product has one RS485 interface and adopts Modbus-RTU

protocol for data exchange.

■ Self-test and reset function. The product has self-test function, which can be activated by long

pressing ▲ button, DI or remote communication. The product has reset function, which can be

activated by long pressing ESC button, DI or remote communication. The reset can be set to

manual or automatic mode.

■ Stop monitoring function. The product can stop insulation monitoring device through DI input, remote communication or submenu "Stop Mode". Currently, the connection between the product

and the earth is break through the internal relay, and the dielectric strength of the relay is 3kV.

■ Monitoring delay function.
