Aventas has had a long-time partnership with Acromag, and is now representing it’s process control and automation products. In this newsletter, we’ll take a look at a couple of their signal conditioning and fieldbus I/O solutions. Acromag I/O is ideal for a broad range of monitoring and control operations where controllers communicate with instrumentation on the plant floor or in the field.

Ethernet Switches

These industrial-grade switches provide reliable network communications. Select managed or unmanaged models for copper or fiber-optic cables.
BusWorks 900EN Series – 5-Port Unmanaged Ethernet Switch
Rugged 5-port industrial-grade Ethernet switches have internal intelligence for fast and easy network installation with auto data rate, flow control, and cross-over. No setup needed if used as a simple switch with Acromag I/O modules.
  • -25 to 70°C range
  • 1500V port-to-port isolation
  • Redundant power support
  • CE, ATEX, UL/cUL Class 1, Div 2 approvals
EIS Series – 8-Port Managed or Unmanaged Ethernet Switch
Acromag switches are designed for harsh environments. Featuring a rugged IP30 aluminum case, 300,000 hour MTBF, and power supply redundancy, you can depend on Acromag for your network.


  • Fast redundant ring technolgy (<300mS)
  • Support STP and RSTP redundant protocols
  • -10 to 70°C operating temperature range
  • Port-to-port isolation (1200V AC)
  • Built-in RFI/EMI and surge/transient protection
  • Wide range 12-48V DC redundant power with reverse polarity protection
  • IEEE 802.3, 3u, 3x compliant

Multifunction I/O

These modules combine analog and discrete I/O functions on a
single unit.
BusWorks 900EN Series – Analog I/O Modules
Mix analog and discrete I/O on a single module with these combination I/O modules. Combine the functionality of three separate models on one unit. Interface sensors or process signals to the network, drive devices or instruments, and monitor or control discrete devices.
  • Universal I/O ranges
  • 16-bit A/D and D/A converters for precise measurements
  • Bi-directional discrete I/O for easy loopback monitoring

Relay I/O Modules

Acromag offers a wide variety of high-density isolated digital I/Oand signal conditioning modules. Multi-channel mechanical and solid-state relay modules perform interposing relay and optocoupler functions. The 8B series offers 100+ models that interface to a variety of voltage, current, temperature, position, frequency, and strain measuring devices.

XTA Series – Multi-channel Interposing Relay and Optocoupler AC/DC Digital I/O Modules

Multi-channel DIN-rail AC/DC digital I/O modules provide space-saving interface for mechanical and solid-state relays to perform interposing relay and optocoupler functions.  


  • 6 optocoupler channels or 6 digital I/O channels
  • 120V AC/DC input with optical isolation
  • Universal 5/12/24V logic inputs
  • Form A, 250V AC / 30V DC @ 5A relay outputs
