The CAL9400 Microcomputer Temperature Controller


The display shows the measured process variable in green at the top. The setpoint value is displayed in orange at the bottom. The dAC function significantly reduces overshoot, featuring one variable temperature segment and one holding segment. Dual-wire PT100 or thermocouple sensor input, 51 x 51mm front panel (45 x 45mm panel cutout).
