The two relays can be programmed to a variety of alarm and control
functions. The relay contacts are all rated at 2A at 240V AC. All
connections should be such that the short circuit capacity of the circuit to
which they are connected, is limited by fuses rated so that they do not
exceed the relay rating.
Voltage Output
This is a non-isolated voltage output of 0 to 5VDC into a minimum load of
10KΩ.
RS232 Serial Interface
The serial interface is used to programme the blackbox either via a PC
(standard) using the software supplied or alternatively using the hand held
calibrator (optional).
