TPR-8208 – Transformer Protection Relay

TPR-8208 – Transformer Protection Relay

The TPR-8208 offers 4 / 8 channel monitoring with advanced functions and full programming features with touch sense keys in IP65 weather proof protection for monitoring process values and protection application.
The TPR-8208 is developed to safely operate medium voltage cast resin/dry type transformers at 70 °C extreme temperature. It is appropriate for installation in marshalling boxes and control rooms.
TPR-8208 has option for 4/ 8 channels accepting universal input and 4 relays to serve various applications. The unit has separate numeric displays for CH. No., Group and process value. All configuration and calibration can be done from front keypad.
TPR-8208 has 4 relays with full mapping and logic flexibility. User has facility to program alarm, trip, Fan, Fault set-points and logic individually or group wise. Channels can be configured up to 4 groups with one relay per group; 2 groups with 2 relays per group or 1 group with 4 relays per group. Two discrete LEDs are provided per channel and one LED per relay for indication.
The TPR-8208 is made with the purpose of storing each channel’s maximum temperature. This feature display & store the maximum temperature prior to a Sensor Fault event and clears it to get a fresh reading.
TPR-8208 has built-in Isolated RS-485 serial communication port with modbus RTU protocol and provides optional analog retransmission output with max./ min. to further interface with PLC/DAS/DCS/ SCADA.
TPR-8208 is a wall mounting unit with 6 nos of PG11 glands for multi-core cable wiring. However 8 channels has an optional possibility of upto 12 nos. PG11 glands.
