The GIA 20 EB is a microprocessor-controlled displaying, monitoring and controlling device for universal use.
It has a universal input for standard signals (0..20 mA, 4..20 mA, 0..50 mV, 0..1 V, 0..2 V and 0..10 V), resistance thermometers (Pt100 and Pt1000), thermocouples (type J, K, N, S and T) and frequency (TTL and switch contact). Additionally it provides functions like rotation speed measurement or counter.
The GIA 20 EB is equipped with switching outputs. The output functions can be configured as 2-point controller, min/max alarm, 3-point controller, 2-point controller with min/max alarm, etc. The relay state is indicated by 2 additional LEDs below the 7-segment display.
The device identifies impermissible operating states like display or system errors and displays a corresponding error code.
