Product Description
CH Series Temperature Controllers – NIK SENSO TECH
The CH series temperature controllers feature standard panel mount designs, PID control, Auto-tuning, and 4-digit LED displays, making them suitable for various industrial applications.
Product Overview
1. CH102 Temperature Controller – Size 48×48 (1/16 DIN)
The CH102 is the most compact model in the CH series, with dimensions of 48×48 mm. It features a 4-digit LED display (red and green) showing both Process Value (PV) and Set Value (SV) simultaneously. The CH102 supports various thermal sensors (Thermocouple and RTD) and provides relay and SSR outputs. This model is ideal for precise temperature control in small machinery, packaging equipment, and laboratory applications.
2. CH402 Temperature Controller – Size 48×96 (1/16 DIN Vertical)
The CH402, with dimensions of 48×96 mm, is one of the most widely used models in the CH series. It features a 4-digit LED display, PID control, and Auto-tuning capability. The CH402 offers versatile inputs (Thermocouple and RTD) and relay and SSR outputs, making it suitable for temperature control in furnaces, plastic injection machines, and packaging industries. The vertical design allows installation in limited space areas.
3. CH702 Temperature Controller – Size 72×72
The CH702, with dimensions of 72×72 mm, offers a balanced combination of size and advanced features. It includes a 4-digit LED display, precise PID temperature control, and Auto-tuning capability. The CH702 supports various sensors and provides relay and SSR outputs, making it ideal for rubber, packaging, and thermal system applications. This non-standard size is designed for applications requiring a larger display than 48×48 but where 96×96 space is not available.
4. CH902 Temperature Controller – Size 96×96 (1/4 DIN)
The CH902 is the largest model in the CH series, with dimensions of 96×96 mm. It features a large 4-digit LED display showing both PV and SV simultaneously with high visibility. The CH902 offers extensive inputs, relay and SSR outputs, and high control accuracy, designed for heavy-duty industrial applications such as large furnaces, steam boilers, and advanced thermal systems. The 1/4 DIN size provides excellent readability for operators.
