management are performed using a Windows™ configuration
program on a PC.
SPECIFICATIONS:
Note: All specifications are given for the Reference Test
Conditions as listed later in this section.
DEFINITION: This DC-powered, SmartPack module conditions
four DC voltage inputs, and converts these signals to network
variables using standard network variable types (SNVT). The
analog inputs share a common ground. As a group they are
isolated from the network and power. This module is DIN-rail
mounted.

FUNCTION: Code number used to represent the module’s
firmware functionality.
-504: See the network variables section for a description of
the module’s standard network variable types and operation.
INPUT: This unit has four independent analog inputs with
software selectable output scaling ranges. Zero and Full-
Scale calibration/scaling of each input is done over the
network. Virtually any part of the input range can be scaled to
output values in the range of -100% to +100%. There are no
potentiometers to adjust.

Isolation: Three-way isolation: input, network and power are
isolated from each other for common-mode voltages up to
250V AC, or 354V DC off DC power ground, on a continuous
basis (will withstand 1500V AC dielectric strength test for one
minute without breakdown for all combinations except
between the input and network circuits which will withstand
1000V AC dielectric strength test for one minute without
breakdown). The 1500V AC dielectric strength test complies
with test requirements outlined in ANSI/ISA-S82.01-1988 for
the voltage rating specified.
POWER: Connect an external DC power supply to the Power (P)
and (-) terminals. Currents specified are maximum values
with full-scale input voltage (each input), and the module
transmitting on the network. An internal diode provides
reverse polarity protection.
-10: +10 to 36V DC, current draw is a function of supply
voltage (refer to Table 3 below).

CAUTION: Do not exceed 36V DC peak, to avoid damage to the
module.
Power Supply Effect:
DC Volts: Less than
±
0.001% of input span change per volt
DC, for rated power supply variations. 60/120 Hz ripple:
Less than
±
0.01% of input span per volt peak-to-peak of
power supply ripple.
Reset/Service Toggle Switch:
Reset Position: Allows the module to be reset to power-up
conditions (toggle right).
Service Position: Causes the Neuron® chip inside the node
to transmit its unique 48-bit ID and 8-byte program ID string
(toggle left).
