Introduction
The Model 682A09 Series Industrial in line ICP to 4-20mA converter transfers the signal from any 100 mV/g ICP
industrial accelerometer to 4-20mA overall vibration velocity. The converter outputs a 4-20mA signal that is
proportional to the overall velocity and raw acceleration of the machinery. Ideal for monitoring the vibration of
process equipment such as fans, motors and pumps, the output of the converter is routed to a PLC, DCS or
SCADA system and used for process control or predictive maintenance.
General Features
•
Loop powered, works with an open analog channel on PLC, DCS or SCADA system.
•
Vibration range in velocity scaled for 0-1 inches per second peak
•
Allows for continuous vibration monitoring of critical applications.
•
Reduces the need for sophisticated vibration analysis requirements.
•
RV (Raw Vibration) output for conducting frequency analysis and machinery diagnostics.
•
Readily interfaces to existing process control and predictive maintenance equipment.
•
Rugged stainless steel construction for applications in harsh environments.
Operation and Wiring
Standard Wiring
The Model 682A09 Series operates from a standard 2-wire, 4-20mA loop. If using a loop power, attach at 3-Pin
connector side the positive (+) input from the power supply to Pin A and the negative (-) input from the power
supply to Pin B. Pin C is a buffered raw acceleration output (Fig. 1). At ICP side (2-Pin connector) attach Pin A (+)
to positive terminal of ICP sensor and Pin B (-) to negative (common) terminal of ICP sensor (Fig. 2).
