■
Power requirements—the
SR107AD, SR108AD and
SR109AD will accept
24 VAC/DC
Inputs—the SR107AD,
SR108AD and SR109AD
will accept single or dual N/C
inputs or dual PNP solid-state
inputs from a light curtain (see
SR102AM for application wiring
for a light curtain)
Outputs—the SR107AD,
SR108AD and SR109AD have a
total of 4 N/O outputs with 3, 2
or 1 of the outputs with a time
delay of 1-30 sec.
■
■
External Device Monitoring
(EDM) is provided with a N/C
loop between S12 and S21 on
the SR107AD, SR108AD and
SR109AD
Reset mode—a monitored
manual start or an auto/manual
start may be configured with
the SR107AD, SR108AD and
SR109AD. Monitored manual
reset requires closure of the
reset circuit followed by opening
of the circuit. Reset occurs when
circuit is opened. Auto reset
requires only closure of the reset
circuit as reset occurs when
circuit is closed.
Conforms to EN60204-1, EN954-1, EN292, VDE 0113-1
UL and C-UL listed, BG approved
■
PLC Compatible—The N/O
off delayed outputs make it
possible to use the SR107AD,
SR108AD and SR109AD on
machines with Programmable
Logic Controllers that require
some time to execute an orderly
shutdown
