TB 14 = Discrete output
The discrete output is used to give a signal to a control system or an operator
panel. The output is software configurable and can be either turned on or off by
the use of a number of flags such as shutdown, alarm, etc.
The electrical circuit is a low-side switch with the return current going to supply
minus, TB 9. It is possible to drive a relay if more current is needed for the load. If
the load is below 0.5 A, the load can be driven directly from the output.
The output is current protected and shuts down if driven above 0.5 A. If the short
is removed, the output returns to normal operation automatically.
Analog Input
TB 4 = Analog Input Plus Signal
TB 5 = Analog Input Minus Signal
TB 3 = Shield (shared)
The Analog input is used when an analog position command is required. The
input can be either (4 to 20) mA, (0 to 5) V (dc), or (0 to 200) mA (dc). Jumpers 3
and 5 are used to select the input range. The values corresponding to min and
max position can be modified using the Service Tool (see Chapter 5).
Set jumpers with power turned off.
Connect the Analog Input sensor between TB4 (+) and TB5 (–). The conductor
shield must be connected to TB3 and the other end of the Analog Input sensor
cable shield is not connected and is isolated. The Analog Input and the Analog
Output signals share the shield connection.
