Input Conversion Rate:
80ms per channel, or 480ms for six input
channels.
Input Filter:
Normal mode filtering, plus digital filtering optimized and
fixed per input range within the
Σ
-
∆
ADC.
Input Filter Bandwidth:
-3dB at 3Hz, typical.
Noise Rejection (Normal Mode):
40dB @ 60Hz, typical with 100
Ω
input unbalance.
Noise Rejection (Common Mode):
140dB @ 60Hz, typical with 100
Ω
input unbalance.
Data Types:
Percentage - A 16-bit signed integer value with resolution
of 0.005%/lsb.
±
20000 is used to represent
±
100%. For example,
-100%, 0%, and +100% are represented by decimal values –
20000, 0, and 20000, respectively. The full range is –163.84% (-
32768 decimal) to +163.835% (+32767 decimal).
Note:
Channels 0, 1, & 2, and channels 3, 4, & 5 (every group of 3
channels) must share the same input configuration, but this configuration
may vary between the two groups.
Dimensions:
1.05 inches wide, 4.68 inches tall, 4.35 inches deep. Refer to
the dimensions drawing at the front of this manual.
DIN Rail Mount:
Type EN50022; “T” rail (35mm).
I/O Connectors:
Removable plug-in type terminal blocks rated for
15A/300V; AWG #12-24 stranded or solid copper wire.
Network Connector:
8-pin RJ-45 connector socket with metal shield
(shield is bypassed to earth ground at the GND terminal via an isolation
capacitor and TVS). Connections are wired MDI, as opposed to MDI-X.
You must use a CAT-5 crossover cable to connect this module to a PC.
Otherwise you may use an auto-crossing Ethernet switch, such as the
Acromag 900EN-S005 to make connections.
