The circuit below shows suggested
wiring for Output 1 of the Orator
Logic facilities Maximum current
through the output stage must be
limited to 200mA and the maximum
permitted external voltage is +200V.
If these limits are exceeded, the
card may be damaged.
To activate a logic input, connect the
relevant logic input pin to ground. A
typical example of the external
circuitry for the logic outputs is
shown below.
