The electrical rating for all open collector
outputs is 100mA @ 35 Vdc.
Figure 8 illustrates some typical open
collector external circuits.

NOTE: When any Open Collector Output
is connected to a device not powered by the
same supply powering the TA402A, it will be
necessary to remove (cut) Jumper W11 (see
figure 33 on page 35).
The terminal designation for the Card Test
Input is:
La bel Term
CT 16d
The Card Test Input is provided so that the
user can access the Card Test feature
remotely. One end of a normally open
SPST switch is connected to this termination
and the other end is connected to system
common. To activate the feature, simply
press and hold the switch for as long as the
test time is to be run (the minimum runtime
for this test is equal to the A2 time delay).
Figure 9 is a block diagram that shows the
switch connections for the Card Test feature.

The terminal designations for the Analog
Output Signal are:
La bel Term
AO+ 20d
AO- 22d
If the Analog Signal is not used a
jumper must be placed between 20d &
22d.
Figure 10 is a diagram of the Analog Signal
connections.
