Interlock
Fig. 2.5 – Interlock section
This section allows to enable/disable the module output and includes:
1 AMP 280372-2 type connector
1 red LED
The Interlock can work in two ways:
PASSIVE OPERATION:
it is necessary to short circuit pin 1 (“GND”, the first from left to
right) with pin 2 (“K=katode”), and pin 3 (“A=anode”) with pin 4 (“VCC”).
ACTIVE OPERATION: it is necessary to send a voltage level (for example a TTL; the
recommended current is about 10 mA) between pin 2 = katode and pin 3 = anode (high =
interlock disabled, the channel can be turned on; low = interlock enabled, the channel
cannot be turned on), leaving pin 1 and pin 4 disconnected.
The LED is ON when the Board is enabled.
