CH402 Temperature Controller Introduction:
- CH402 temperature controller (48*96mm width*height) is a universal input (various temperature sensors optional) PID digital controller.
- It is a cost-efficiency, low price pid temperature controller, working on wide power source from 85-265VAC or 24VDC.
- Equipped with relay(or AC contactor) and SSR drive output at the same time, the output is field selectable, it is output field selectable temperature controller.
- The shell is made by high quality&price competitive ABS, this material is flame retardant, it is strong and not easy to corrode.
- Used for electric oven, electric heater, plastic injection, extruder machines etc., also, it can be used as temperature indicator to show detected materials temperature.
- Order code explanation for instance: CH402-FK02-M*AN, 48*96mm panel size, input K thermocouple range 0-400℃, relay output, 1 deviation high alarm.
