Keller psi series 3000 process control 3 1/2 digit
The control loop readout displays process signal measurements in engineering units from all the common control signals. The front panel calibration controls for both HI and LO adjustments allow the user to display in engineering units. The built-in loop power supply will drive not only the transmitter, but other devices in the loop such as recorders, controllers, and intrinsic safety barriers.
Loop Power: Up to 20 mA at 24 VDC regulated. Noise less than 10 mV peak to peak. Max. loop resistance of 1200 ohms.
Display: Bright, large, 0.56" (14.2mm), high efficiency red LED. (0) may be switched on to display to 19,990.
Inputs: Switch selectable, 4-20 mA, 1-5VDC, 0-5VDC, 0-10VDC, -10 to +10VDC
Calibration range: 4 mA (1V) input: -1500 (0) to +1500 (0). 20 mA (5V) input: between 20(0) and 2000(0) counts greater than the 4 mA display.
