Modes of Operation

Table 1-1 summarizes the modes of operation for the Relay Driver Module.
For 36-channel operation, note that CNFG 1 sets the actuation mode
(simultaneous actuation or stepped actuation) for the channel pairs, while
CNFG 2 sets the method of current output from the channel pairs
(continuous output or pulsed output).

Table 1-1. Relay Driver Module Operating Modes

Operation

Switching One Channel

Switching

Multiple Channels

Scanning
Channels

72-Channel Mode (Set when CNFG 0 is Open)

OPEN (@ccnn) opens
the channel and CLOSe
(@ccnn) closes the channel.

All channels in the
OPEN/CLOSe

channel_list

are actuated nearly
simultaneously.

A 60-msec delay occurs
between actuations of each
channel in the SCAN

channel_list

.

36-Channel Mode Actuation (Valid only when CNFG 0 is connected to GROUND)

Simultaneous
Actuation
(CNFG 1 Open)

OPEN (@ccnn) opens
the channel pair and CLOSe
(@ccnn) closes the channel
pair.

All channel pairs (SET/
RESET) in the OPEN/CLOSe

channel_lis

t are actuated

nearly simultaneously.

A 60-msec delay occurs
between actuations of each
channel pair in the SCAN

channel_list

.

Stepped Actuation
(CNFG 1 connected
to GROUND)

OPEN (@ccnn) opens
the channel pair and CLOSe
(@ccnn) closes the channel
pair.

A 30-msec delay occurs
between actuations of each
channel pair in the OPEN/
CLOSe

channel_list

.

A 60-msec delay occurs
between actuations of each
channel pair in the SCAN

channel_list

.

36-Channel Mode Current Output (Valid only when CNFG 0 is connected to GROUND)

Continuous Output
(CNFG 2 Open)

The SET or RESET output
current is continuously
applied to the channel pair
when actuated.

The SET or RESET output
current is continuously
applied to the channel pair
that is actuated.

The SET or RESET output
current is continuously
applied to the channel pair
that is actuated.

Pulsed Output
(CNFG 2 connected
to GROUND)

When the channel pair is
actuated, the SET or RESET
output current is applied until
the 30 msec timer indicates
the channel has finished
moving. The current is then
removed, and another 30
msec wait occurs.

The SET or RESET output
current is applied to the
actuated channel pair until
the 30 msec timer indicates
the channel has finished
moving. The current is then
removed, and another 30
msec wait occurs

This process is then repeated
with the next channel pair
in the OPEN/CLOSe

channel_list

until the list is

completed.

The SET or RESET output
current is applied to the
actuated channel pair until
the 30 msec timer indicates
the channel has finished
moving. The current is then
removed, and another 30
msec wait occurs.

For scanning, pulsed output
requires twice as much time
as continuous output to
complete the operation.
