The KS 90-1 process controller is suitable for universal, precise, and cost-effective control. The instrument provides simple 2-point (on\/off) control, continuous PID control, or 3-point stepping control. The process value signal is connected via a universal input. A supplementary analog input can be used for heating current measurement, as an external set-point inputter for position feedback measurement of motorised stepping controllers. The optional 3rd input is a universal input that can be used for several functions, e.g. temperature dependent setpoint correction or differential control. The standard KS 90-1 is suitable for oxygen control using heated and unheated O2 sensors. The KS 90-1 is particularly suited to the following applications: Furnaces and ovens, Burners and boilers, Plastics processing & Driers.• BluePort®. • Front interface and BlueControl software. • Maintenance manager and error list. • Two universal inputs. • Day & Night display shows plain text and bargraphs. • Manual gain scheduling. • Self-Tuning to the setpoint without oscillation. • Valve controller with position feedback and DAC monitoring. • 3-point controller for water, fan and oil cooling. • Type tested to EN 14597 (replaces DIN 3440) and cULus. • High-impedance mV input for O2 sensorsOutput Type = RelaySupply Voltage = 90 - 250 V acSize = 96 x 48 (1\/8 DIN)mmNumber of Outputs = 3Minimum Operating Temperature = -20°CMaximum Operating Temperature = +65°CTemperature Range = 0 - +1760 (Type R Thermocouple) °C, 0 - +1760 (Type S Thermocouple) °C, 0 - +1820 (Type B Thermocouple) °C, 0 - +2315 (Type C Thermocouple) °C, 0 - +2315 (Type D Thermocouple) °C, -100 - +1000 (Type E Thermocouple) °C, -100 - +1200 (Type J Thermocouple) °C, -100 - +1300 (Type N Thermocouple) °C, -100 - +1350 (Type K Thermocouple) °C, -100 - +900 (Type L Thermocouple) °C, -200 - +200 (PT1000) °C, -200 - +400 (Type T Thermocouple) °C, -200 - +850 (PT100) °CControl Type = ON\/OFFConfigurable Outputs = RelayDisplay Type = LED, Multi Line
