Product Description:

YJJ DC1020CT-30200B-E PID Temperature Control Meter for Heat Treatment /Baking Equipment

Features:

I. Interpretation of Complete Model Segments DC1020CT-30200B-E

DC1020: Series size 48mm × 96mm (8/8 DIN vertical panel)

CT: Input type = T = Special input for thermocouples (K/J/R/S/B/E/N/T/W etc. 12 types of thermocouples), cannot directly be PT100 thermoresistor

3: Main control output OUT1 = 4~20mA analog current continuous PID output

0: Second control output OUT2 = None

2: Alarm channel = 2 independent relays for alarm (AL1 + AL2)

00: No transducer output, no external remote setting SP

B: Built-in RS485 Modbus-RTU communication (can be networked to PLC / touch screen)

E: English operation menu interface

II. Core Hardware Electrical Parameters

1. Thermocouple input (CT standard)

Compatible thermocouples: K, J, R, S, B, E, N, T, W5Re/W26Re, PLII, U, L, a total of 12 types

Measurement accuracy: Full scale ±0.5% FS, display resolution 0.1℃

Sampling period: 250ms / time

Breakdown detection: Thermocouple open circuit automatically triggers fault alarm

2. PID main control output (4~20mA)

Output specification: 4~20mA DC, maximum load 500Ω, no contact continuous proportional regulation

PID parameter range:

Proportional band P: 0~200% (P=0 is switch ON/OFF control)

Integral I: 0~3600s; Differential D: 0~900s

Support automatic self-tuning AT, manual / automatic without disturbance switching A/M

Output period: 0s (current output has no mechanical delay, suitable for electric proportional valve, SCR regulating power supply)

3. Two alarm relays (AL1, AL2)

Contact specification: single-pole double-throw SPDT, 3A / 240VAC resistive load

Built-in 17 alarm modes: upper and lower limit absolute value, deviation alarm, open circuit fault, heater open circuit, standby warning, etc.

Two independent can be set thresholds separately, one for over-temperature shutdown, one for warning reminder

4. RS485 Modbus communication (core function after B suffix)
