Introduction
The Model 683A1 ICP
®
Process Indicator/Controller is an
intelligent 4-digit modular panel meter with software
features for monitoring, measurement, and control applications complete with 0.56
”
LED in a 1/8 DIN 96x48 case.
The 683A1 operates from a single power supply and will supply 24Vdc/4mA excitation for sensor power. The
indicator/controller comes equipped with two 5 Amp Form A relays with independent setpoints and time delay.
General Features
External transmitters, signal conditioners, or power supplies can be eliminated by direct connection of the
sensor to the indicator/controller.
Optional isolated 16-bit analog output. User or factory scalable to 4 to 20 mA across any desired digital
span from ± one count to the full-scale range of
–
1999 to 9999 (12000 counts).
24Vdc/4mA excitation to power sensor.
Standard Internal DIP switch selectable vibration ranges include:
