Description
DELTA DTA4848R1 Temperature Controller
The DELTA DTA4848R1 is a compact digital temperature controller from Delta’s DTA / A Series, designed for industrial temperature monitoring and control applications.
The controller comes in a 48 × 48 mm panel size, also known as 1/16 DIN, making it suitable for machine panels, heating systems, ovens, packaging machines, process control panels, and general industrial automation systems.
The DTA4848R1 supports PID control, ON/OFF control, and manual tuning, allowing flexible temperature control according to the application requirements. It supports thermocouple and RTD temperature sensor inputs, including K, J, T, E, N, R, S, B, U, L, TXK, and Pt100 / JPt100.
This model includes a relay control output and RS-485 communication, making it suitable for integration with PLC, HMI, SCADA, and industrial monitoring systems. Delta’s DTA instruction sheet identifies communication option “1” as RS-485, and lists serial communication parameters including baud rates from 2,400 to 38,400 bps.
