Description

Drive position sensor DP-4 is designed to determine actual transformer tap on load. This sensor may be connected to the MZ-2, MZ-3, MZ-4 type drives. Sensor DP-4 is an electronic sensor of drive turn angle with the signal conversion circuit; it can be used instead of resistive sensor.

Sensor DP-4 has different interfaces in order to transmit a drive turn angle. These are: interface RS-485 for the transformer tap data transfer to PCS or UP 25 OLTC Position Monitors in digital form via MODBUS protocol. "Current loop" analog current interface 4-20 A, 0-5 mA or 0-20 mA is designed for the transformer tap data transfer to UP 25 OLTC Position Monitors or PCS by additional transmitters. Analog interface 0-5 V or 0-24 V is used for the transformer tap data transfer to UP 25 or PCS by additional transmitters. When using this interface sensor DP-4 can function as a resistive sensor of MZ-2, MZ-4, EM1, MR, ED-S drives, the sensor can be used for connecting Siemens and ABB transformer protection and control automatics to drives.
