Product Overview
The ABB DTPC721B 3EST126-236 is likely an intelligent temperature protection and control unit with the following core functions:
Temperature Monitoring:Real-time monitoring of equipment temperatures(such as motor windings and transformer oil temperature)using built-in or external temperature sensors(e.g.,Pt100,thermocouples).
Protection Functions:Integrated over-temperature alarms,trip protection(e.g.,over-temperature shutdown),and temperature trend analysis to prevent equipment damage due to overheating.
Control Output:Supports relay contact outputs(for controlling cooling fans,heaters,or circuit breakers).
Communication Integration:Possibly supports protocols such as Modbus RTU/TCP and Profibus DP,facilitating integration with PLC or SCADA systems.
Display and Operation:Equipped with a digital display or indicator lights for real-time temperature display,fault code query,and parameter setting.
Core Parameters and Features(Estimated)
Temperature Monitoring
Sensor Type:
Supports Pt100(three-wire),thermocouples(K/J type),or NTC/PTC thermistors.Measurement Range:
Estimated range:-50°C to+200°C(model prefix”126″may indicate a specific range).
Accuracy:
±0.5°C(typical value,may vary slightly depending on sensor type and environmental conditions).
Sampling Frequency:
1/second to 1/minute(configurable,balancing real-time performance and power consumption).
Protection Functions:
Overtemperature Alarm:
Set two thresholds(e.g.,warning and trip levels)to output an alarm signal when triggered.
Tripping Protection:
When the temperature exceeds the set value,a relay contact disconnects the power supply or activates the cooling system.
Delay Function:
Supports alarm/tripping delays(e.g.,5s to 300s)to prevent false alarms.
Fault Log:
Stores the most recent 10 to 100 fault events(time,temperature,and fault type).
