CKCTINNER PID Temperature Controller – Dual Output SSR & Relay LCD
CKCTINNER REX-CH Series LCD PID Temperature Controller with Dual Output SSR & Relay
Take precise command of your industrial or DIY temperature processes with the CKCTINNER REX-CH Series Intelligent PID Temperature Controller. Available in four panel sizes (CH102, CH402, CH702, CH902), this CE-certified unit combines a dual output — electromagnetic relay and SSR — with a bright 4-digit LCD display and a versatile 2-alarm system for complete, hands-off process control.
Why Choose the REX-CH Series?
- Dual Output: Electromagnetic relay + SSR output gives you flexible control options for heating or cooling applications.
- Intelligent PID or ON/OFF Control: Auto-tune PID algorithm ensures accurate, stable temperature regulation; switch to simple ON/OFF mode when needed.
- Wide Input Compatibility: Supports thermocouples (K, J, R, S, B, E, N, T, W5Re/W26Re, PLII), RTD (Pt100, JPt100), voltage (0–5V, 1–5V), and current (0–20mA, 4–20mA) — works with virtually any industrial sensor.
- 2 Independent Alarms: Choose from 12 alarm modes including deviation high/low, band, process high/low, and hold-action variants for comprehensive process protection.
- High Accuracy: ±0.5% FS ±1°C measurement accuracy for consistent, reliable results.
- Universal Power Supply: Operates on 100–240VAC — plug in anywhere worldwide.
- Clear LCD Display: 8-segment, 4-digit readout with LED indication for at-a-glance monitoring.
- Intuitive Touch-Switch Setting: Easy parameter entry without tools or complicated menus.
- Multiple Panel Sizes: Choose the model that fits your panel cutout perfectly.
- Made in Mainland China.

Frequently Asked Questions
Q: What sensor types are compatible with the CKCTINNER REX-CH series PID temperature controller?
A: The REX-CH series supports a wide range of input types including thermocouples (K, J, R, S, B, E, N, T, W5Re/W26Re, PLII), RTD sensors (Pt100, JPt100), voltage inputs (0–5V, 1–5V), and current inputs (0–20mA, 4–20mA), making it highly versatile for industrial and laboratory applications.
Q: What is the difference between the CH102, CH402, CH702, and CH902 models?
A: The models differ in their external and panel cutout dimensions. CH102 is 48×48mm, CH402 is 48×96mm, CH702 is 72×72mm, and CH902 is 96×96mm. All share the same core features — dual output (SSR + relay), 2 alarms, PID/ON-OFF control, and 100–240VAC supply — so you can choose the size that best fits your control panel.
Q: Does this PID temperature controller support auto-tune PID?
A: Yes. The REX-CH series features intelligent PID control that automatically calculates and adjusts proportional, integral, and derivative parameters for stable and accurate temperature regulation. It can also be switched to simple ON/OFF control mode as needed.
Q: What power supply does the REX-CH temperature controller require?
A: It operates on a universal 100–240VAC power supply, making it compatible with standard electrical outlets worldwide. Power consumption is under 10VA for the AC100–240V version.
