IO Modual
1.1 The Purpose of IO Modules
Acuvim II meter does not have any IO functions itself, but it can realize
multi IO functions with IO modules, such as digital input, counter of
pulses, relay output, analog output, and analog input and so on.
There are three types of IO modules, AXM-IO1, AXM-IO2 and AXM-IO3.
According to the difference in communication with Acuvim II meter, each
type of IO module also has two modes, sub address 0 and sub address 1.
That is, two of each type of IO module, one is sub address 0 and another
is sub address 1, can be linked to Acuvim II meter at one time.
AXM-IO1 module, which is adapted to low voltage power distribution, is
composed of:
6 digital inputs (DI), each digital input can be used to detect remote
signals, or be used as a counter of input pulses. When it is used to detect
remote signals, it also can enable SOE(sequence of events), recording the
event and time of the event.
2 relay outputs (RO), it can work in controlling mode, or work in alarm
mode. Both of 2 relay outputs work in the same mode. When it works
in controlling mode, it has two optional output modes, latching mode
and pulse mode. When it works in alarm mode, it has only one latching
output mode.
24V isolated power supply; it is used as an auxiliary power supply for
digital inputs.
AXM-IO2 module,
which is adapted to factory DCS (or processing
controlling, BA), is composed of:
