The unit also offers three normal operating modes, including configuration, operation, and calibration modes.

The unit includes two redundant speed inputs that can accept magnetic pickup units, eddy current probes, or proximity probes. It has analog inputs (8) that can be configured for any of twenty-seven functions.   The unit also has an additional twenty contact inputs.  The first four of these contacts default for shutdown raise speed setpoint, reset, and lower speed set point.  The others can be configured as needed. Additionally, the unit has two 4-20 mA control outputs and eight Form-C relay contact outputs.

The 8200-1302’s front panel includes an emergency trip key, a backspace/delete key, a shift key, as well as view, mode, ESC, and home keys.  It also has navigation cross keys, soft key commands, and four LEDs to relate the status of control and hardware.
