Model NGA 2000 Platform
SECTION 4
SYSTEM SIO MODULE
4-1 OVERVIEW
The SIO module is an optional card that plugs
into the platform. Since it is not part of the
LON network, it does not require binding but it
must be configured to assign the desired
Analyzer module and module signal to the
various outputs. Only one SIO module can be
installed per platform. The SIO module is
available with 2, 4, 6, or 8 channels of analog
output and a serial interface (RS-232 or RS-
485) and relay contacts.
The system SIO module is a circuit card that
plugs into the rear of the Platform. The func-
tions provided are as follows:
• Dual channel analog output pro-
vided as both a voltage and a
current. The voltage output is
configurable as 0-10V or 2-10V
(load > 2KΩ). The current output
is configurable as 0-20mA or 4-
20mA (impedance 500Ω).
• Optional sub-modules to provide
4, 6, or 8 analog outputs as de-
scribed above.
• Optional RS-232 or RS-485 (Rx,
Tx) output sub-modules.
• Three configurable relays
(SPST) rated at 30V / 1A / 30W
maximum.
The analog outputs can be assigned to the
various signals from any Analyzer module
connected to the Platform. The relays can be
assigned to various discrete signals from any
Analyzer module connected to the Platform.
The RS-232 or RS-485 outputs can be used
to communicate from any Analyzer module
connected to the Platform to peripheral de-
vices.
Since the SIO module is not a LON module, it
is not bound to the Analyzers.
