Series 401 Digital Indicating Temperature Controller

□ Push to set
□ For process control to 400° C
□ Proportioning control with manual reset

□ LED display of process and set-point temperatures
□ Tracking high-low alarm output

Model 401 is a small 1/8 DIN Digital Indicating Temperature Controller providing adjustable time proportioning control for K thermocouple input with manual reset and tracking high-low alarm outputs. A 3-digit display shows either process or set point temperature with indication of alarm and sensor failure conditions. Range is to 400° C and the unit is suitable for platen, kiln, furnace and oven applications. Model 401 provides field adjustable display offset, alarm limit and manual reset with high set-point stability and output transient immunity
