8B I/O Modules

Acromag offers a wide variety of high-density isolated digital I/O and 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.



• Systems requiring high channel-to-channel isolation, noise rejection, surge suppression, and amplification
• Designed for front-end signal conditioning or embedded applications:
  - DCS, PLC, controllers, data acquisition, remote I/O, recorders, etc.
  - Interfacing AC/DC solid-state or mechanical relays
  - Acromag EtherStax® analog and discrete I/O modules
  - Acromag BusWorks® analog and discrete I/O modules
  - Acromag VME, Industry Pack, PCI, and CompactPCI analog I/O modules
  - On-board embedded OEM applications
• Protects equipment, increases accuracy, and installs/expands easily
• Low-cost, high-density amplifier system
