Remote I/O

Acromag's remote I/O products provide a variety of network I/O and distributed control solutions on many of the popular fieldbuses. Analog and discrete I/O modules interface sensors and actuators to controllers on Ethernet, Modbus, Profibus, and Hart networks.

Signal isolators receive a 4-20mA process current inputs and provide an isolated 4-20mA output signal. One multi-channel units, each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.

Signal conditioner products include process transmitters, 4-20mA signal isolators, limit alarms, panel meters, and math computation modules. These signal conditioning products isolate, amplify, filter, condition, and convert measured signals from sensors and other instruments. The enhanced signal is ready for interfacing to your PLC, DCS, display, recorder, or other process control instrumentation.

Many BusWorks XT, BusWorks 900EN, and EtherStax I/O modules have the ability to operate like a long-distance transmitter using i2o technology. Reproduce your sensor inputs at Point A as 4-20mA control signals at Point B. Or, monitor a discrete device at one site by reproducing the level with a relay at another location.

• Transmits data to/from any PLC, DCS, recorder, or display device
• Reduces wiring costs by interfacing many I/O signals over a single data line without a controller in between

EtherStax high-density I/O blocks are designed for high-reliability operation and process up to 96 I/O channels on a single, vertically-stackable unit. Each I/O block has redundant Modbus TCP/IP network and power ports to ensure dependable operation. Rugged, aluminum enclosures protect against shock and vibration.
