Signal conditioners, transmitters and optical isolators are used to solve ground loop problems, isolate noise issues, convert signals to desired levels and types, and to allow longer cable runs. Limit alarms take analog inputs and provide low-limit, high-limit, or other discrete output indications based on the input value.
Signal integrity starts with quality measurement and good equipment. However, even with the best equipment, signals can be degraded if the equipment is not properly installed or it is not protected by signal conditioners / signal isolators.
mA, VDC, VAC, thermocouple, RTD, linear resistance and potentiometer input signal types
Analog to Relay Limit Alarm modules that are field configurable for a variety of alarm and control applications.
