Input/Output Circuit Description
2-8
Discrete Outputs
The T6200-C Controller can be configured for up to eight discrete outputs. The T6200-D Controller can
be configured for up to 28 discrete outputs. A 100 volt transient absorber is connected on each terminal to
protect the output transistor and to prevent arching between conductors on the circuit board. Each
terminal is protected with a one ampere fuse.
The output transistor in the standby (not ACTIVE) control board is always open.
Discrete output 32 can be used as frequency output, with output frequencies up to 10 kHz. Other discrete
outputs can be used as frequency outputs with output frequencies up to 100 Hz.
Discrete Outputs with Internal Power
In reference to Figure 2-7, a separate internal +24 volt voltage regulator is provided for each output. Each
voltage regulator has thermal, reverse voltage, and short-circuit protection. The regulator can supply 24
Vdc power for a load up to 20 milliamperes continuously and 100 milliamperes momentarily.
