RC1xx - User Manual
NPN signal
You can connect an NPN open
collector drive to the RC1xx's
input. Use the connections shown
opposite.
If the P flag is set to ‘1’ the RC1xx
output turns on when the driving
transistor turns on. To reverse
this, set the P flag to ‘0’. (see
Section 7.2, Triggering).
Opto-coupler
You can connect an opto-coupler
as an NPN drive to the RC1xx's
input. This prevents a ‘ground
loop’ and reduces spurious
triggering in high-interference
environments.
If the P flag is set to ‘1’ the RC1xx
output turns on when the driving
transistor turns on. To reverse
this, set the P flag to ‘0’ (see
Section 7.2, Triggering
PNP signal
You can connect a PNP open
collector drive to the RC1xx's
input. Use the connections shown
opposite. The PNP transistor
should not pull up to more than
24V.
If the P flag is set to ‘1’ the RC1xx
output turns on when the driving
transistor turns on. To reverse
this, set the P flag to ‘0’ (see
Section 7.2, Triggering).
7.2.2 Internal trigger
You can set the RC1xx to generate its own trigger pulses. The period of
these pulses can be set in increments of 100µs from approximately 10µs
to 5000ms.
You can set the RC1xx to produce a single pulse for testing purpose. This
is set by either a TR1 command (see Section 10.3.3, General commands)
or using the webpage Trigger button (see Section 9, Webpage
configuration (RC120)).
