YJJ DC1040CR-701000-E PID Temperature Control Meter for Combustion Equipment

Features:

I. Interpretation of Complete Model Segments DC1040CR-701000-E

DC1040: Panel size 96mm × 96mm (1/4 DIN square), dual row digital tubes + output beam display

CR: Input type = R RTD thermal resistance dedicated, supports PT100/JPT100/JPT50, cannot directly connect thermocouples / 4-20mA linear signal

7: Main control output OUT1 = Three-digit motor forward/reverse drive output (controls electric proportional regulating valve, open / close contact dual output)

0: Second control output OUT2 = None

1: Alarm channel = 1 SPDT relay alarm output (AL1)

00: No transducer output, no external remote setting SP

0: No RS485 Modbus communication function, only single machine local operation

E: English menu operation interface

II. Core Hardware Electrical Parameters

1. PT100 thermal resistance input (CR standard)

Supports RTD: PT100, JPt100, JPt50 three-wire thermal resistance

Temperature measurement range: -199.9℃ ~ +800.0℃, resolution 0.1℃ Measurement accuracy: ±0.5% of full scale

Line break detection: Automatic fault alarm triggered by open circuit of thermal resistance

Sampling period: 250ms / time

2. Three-way motor valve control output (output 7, core feature)

Output form: Two sets of independent relay contacts (open valve / close valve), driving electric proportional motor valve

Contact capacity: 3A / 240VAC resistive load

Control logic: PID automatic output on/off pulses, automatically calculating valve opening degree, constant temperature closed-loop regulation

Support customizing valve travel time (0~1000 seconds), compatible with steam / hot water electric two-way / three-way valves

Support automatic self-tuning AT, manual / automatic undisturbed switching A/M

PID parameters adjustable:

Proportional band P: 0~200%; Integral I: 0~3600s; Derivative D: 0~900s

3. Single-channel alarm relay AL1

Contact: Single-pole double-throw SPDT, 3A / 240VAC

Built-in 17 alarm modes: upper limit, lower limit, deviation alarm, sensor open circuit, standby warning

Can independently set alarm threshold, used for over-temperature shutdown, sound and light warning linkage

4. Power supply and environment

Power supply: Wide-range universal AC85~264V 50/60Hz, maximum 8VA; optional DC15~55VDC direct current power supply

Working environment: 0~50℃, humidity 20~90% RH without condensation

Protection: Front panel IP65, back panel terminals IP30; industrial EMC anti-surge, motor interference

Parameter storage: EEPROM permanent storage after power loss, no need for backup battery

5. Human-machine display and keys

Dual 4-digit digital tubes: Upper row PV actual temperature, lower row SP set temperature

10-segment LED column: Intuitively display 0~100% valve opening output ratio

Panel keys: SET setting, A/M manual-automatic switching, up and down adjustment keys

Status indicator lights: OUT valve control, AT self-tuning, AL1 alarm, MAN manual mode

6. Mechanical dimensions

Panel: 96×96mm; Cabinet opening: 92×92mm; Overall depth 95mm
