TECHNICAL REFERENCE
•
Safety Agency Approvals
– CE, UL, & cUL listed, plus Class 1;
Division 2; Groups A, B, C, D approval.
•
Fully Isolated
– Input channels (as a group), network, and power are all
isolated from each other for safety and increased noise immunity.
•
Modbus TCP/IP Protocol Support –
Supports up to 10 master sockets
(the maximum number of sockets is user-selectable) using the Modbus
TCP default port number 502.
•
I/O Mapping (i2o) Feature
– I/O Mapping feature allows the inputs of
this device to control the outputs of an Acromag 972EN-400x or
973EN-400x analog output module.
•
Built-In Web Pages -
Allows unit to optionally be configured, controlled,
calibrated, and monitored with a standard web browser over ethernet.
•
Convenient “Wink” ID Mode Support
– Blinks green RUN LED in wink
mode as a visual tool to help identify specific remote units on a network.
•
Fully Independent w/ Direct I/O Connection
– Self-contained with no
special bus couplers, power supply, or rack mount required to operate.
•
Isolated Network Interface
– Immune to noise & can operate over long
distances. Allows many modules to network together.
•
Network Port is Transient Protected
– Shielded RJ45 port includes
transient protection from ESD, EFT, and other transients.
•
10Base-T and 100Base-TX Support
– Integrated IEEE 802.3/802.3u
100Base-TX/10Base-T.
•
Auto-Negotiated 10/100Mbps, Half or Full Duplex.
•
Flexible Multi-Range Analog Inputs
- Accepts either DC current or DC
voltage, according to model number.
•
Range Variability
– The first 3 channels must share the same range,
but this can be different than the range of the last 3 channels.
•
Optional AC Current Input (961EN Only)
- An optional AC current
sensor can be purchased separately to support AC current inputs.
•
Precise High-Resolution A/D Conversion
– Modules use high-
resolution, low noise, sigma-delta analog-to-digital conversion for high
accuracy and reliability.
•
Plug-In Terminal Blocks & DIN-Rail Mount -
Make mounting, removal,
and replacement easy.
•
Nonvolatile Reprogrammable Memory
– Allows the functionality of this
device to be reliably reprogrammed thousands of times.
•
Operation/Diagnostic LED Indicators Aide Troubleshooting
– Yellow
ACT LED indicates port activity (busy). Green LNK LED indicates link
(auto-negotiation complete & connection established). Green RUN LED
indicates power/wink ID mode. Yellow ST LED indicates module status.
•
Self-Diagnostics & Built In Watchdog
- For easy maintenance and
troubleshooting. Includes a hardware watchdog timer built into the
microcontroller that causes it to initiate a self reset if the controller ever
“locks up” or fails to return from an operation in a timely manner.
•
Wide-Range DC-Power
– Wide range diode-coupled for use with
redundant supplies, and/or battery back-up.
•
Hardened For Harsh Environments
- For protection from RFI, EMI,
ESD, EFT, & surges. Has low radiated emissions per CE requirements.
•
Wide Ambient Operation
– Reliable over a wide temperature range.
