Introduction
The Training Panel includes:
•
LED indicators to display the output states of up to four discrete output function blocks (2 relay, 2 digital)
•
Toggle switches to set up to four simulated discrete inputs
•
Plug-in jacks for three analog output function blocks and a switchable voltmeter to monitor the output voltage
•
Four precision potentiometers to set simulated analog inputs
•
Analog input selector switches to connect analog outputs to analog inputs for use in process simulations or
tuning experiments
•
Plug-in jacks to connect the Model 353 to the Local Instrument Link (LIL)
•
Plug-in jacks to connect the Model 353 to LonWorks
•
Ethernet connector (later model Training Panels only)
The switches, potentiometers, and displays permit the simulation of a process and field devices without interacting
with a live process. Engineering, operating, and servicing personnel can become skilled in the use and configuration
of a Model 353 without the threat of a costly process upset.
Possible uses of the Multi-Purpose Training Panel with a Model 353 include: operator training, configuration
development, and controller checkout and calibration.
