Relay Outputs
The two relays can be programmed to a variety of alarm & 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.
Current Output
This is an isolated active mA output of 4 - 20mA or 0 - 20mA, with an option
of a passive mA output. The load should not exceed 1K
.
RS232 Serial Interface
The serial interface is used to program the BlackBox either via a PC
(standard) using the software supplied or alternatively using the handheld
calibrator (optional).
