ioPro 8AO-I 8 Channel Output

iopro 8AO-I

Modbus IO - 8 Channel Current Output

ioPro 8AO-I is an 8 channel current output module.  Each channel can be set to output a current in the range 0 - 20mA.  The outputs are isolated from the logic and share a common negative terminal.

The resolution is 12 bits, so writing a value to the Modbus register for each output of 0 - 4095 would give an output current of 0 - 20 mA.  The value of 819 +/- 1LSB will give a current output of 4 mA.

The module may be used a either a slave or master on a wired Modbus network.  

When used as a slave module, the outputs are written to by the Modbus master device such as a PC or PLC.

Signal Conditioning Solutions



Universal Signal Conditioners with Isolation UniPak from ioSelect

The UniPak family of Universal Signal Conditioners provide the latest in Signal Isolation, and Industrial process functionality available on the market today. Each UniPak product is field configurable for the specific calibration required, eliminating the need to stock several 'fixed range' units to support your system requirements.

The workhorse of the UniPak family is the UP488/Z109REG. The UP488/Z109REG can accept a variety of input types (DC V or I, TC, RTD, Pot, or Resistance) and provide a linearized DC (mA or V) output proportional (or inverse proportional) to the input signal. The UP488/Z109REG can be configured either by push-buttons, DIP switches, PC software, or with a universal handheld calibrator. This one unit can satisfy more than 80% of most signal conditioning requirements all with a single (on the shelf) unit.

For the other 20% of the applications, there are a handful of wide-ranging UniPak products that specifically address these needs: including conditioners for strain gage Inputs, AC voltage or current, frequencies, and specialty functions such as DC splitters, add/subtract modules, and a range of alarm trip units with 1, 2, or 3 configurable setpoints. In the end, there are literally thousands of possibilities with one cohesive family of products.

Small on DIN Rail Space Big on Capabilities, Features, and Performance

The UniPakHD delivers the highest density package available (less than 0.25" thick!), while still providing high-performance signal conditioning, isolation, and alarm trip functionality for a wide variety and range of process signals. All units are wide-ranging and field configurable and operate over a wide temperature range in high-demanding environments.

This product family includes wide-ranging units for DC, TC, RTD, and Frequency Inputs, along with two-wire (loop powered) units for DC, TC, and RTD. A loop isolator that works with HART 4-20 mA loops. All units are DIP switch configurable for custom ranging, can be powered either from front or DIN mount 'power foot' connectors, carry UL/CSA approvals, and provide performance better than a product that costs twice as much (and taking up four times the space!). The UniPakHD is truly a breakthrough in signal interface technology.

This ever-growing family of products is built to demanding specifications by our exclusive signal conditioning partner company, Seneca Instruments. Seneca is the leader in innovative signal conditioning products in Europe, and together we are expanding their capabilities around the globe.

Action Pak Replacements Made Easy From ioSelect

With more than 30 years of experience in signal conditioning technology, you can trust ioSelect to have the product you need with the plug-in compatibility that you require. This is why we offer the industry's widest range of plug-in 'paks', the AccuPak family. From the industry-standard AP4380 to one-of-a-kind specials, ioSelect is your 'one-stop shop' for all your "AP" needs.

While the AccuPak shares the industry standard pin-outs and familiar relay-style packaging that proliferates instrument panels around the world, this is where the similarities end. In just about every technical area, the AccuPak family outperforms the other 'clones' in the market hands down. For example, the AccuPak AP4380 boasts 3-way isolation of better than 1,400 V (not 500 V, like some), and a 4-20 mA output drive of 1200 ohms (not 500 ohms, like some), and a response time of less than 100 msec (not 200 msec or greater, like some). Spec for spec we're better performing, and with our lower price and quick off-the-shelf delivery, the AccuPak is also the better value. For all your signal conditioning needs, ioSelect has your back and your 'Pak'.
