4 Channel RTD Distributed DAQ Input Module

Configurable SCADA Automation with Isolation/Filtering:  Z-4RTD


The Z-NET™ model Z-4RTD has 4 configurable RTD input channels. Each channel can be configured to a different RTD type and have different filtering. The Z-4RTD allows the user to select between higher sampling time or higher resolution. The communications and sampling time are configured through software. The current version of the Z-NET software (requires a CPU module) or Z-PROG may be used for configuration of the Z-4RTD parameters. The Z-NET™ Series offers flexible, cost effective solutions to industry’s increasingly diverse applications including distributed control, data acquisition, SCADA & telemetry. An ideal solution for process control and management using distributed I/O on plant and machinery. The I/O modules can be widely distributed or grouped together and accept all standard field signals.

Modbus RTU protocol guarantees universal connectivity so applications are limitless: data acquisition, automation, telemetry control, etc.

More flexibility from ioSelect.

Strain Gauge Bridge Input Isolating I/O Module Z-SG

Modular, Open, Standard Architecture for Distributed Automation

Z-NET• 6-wire Bridge Connection
• Excitation for 1 to 4 350 Ω Load Cellsbr /> • 1500 Volt (3-way) Isolation
• Excellent Accuracy (0.01%)
• DIP Switch Configuration
• Digital Input Tare Calibration
• RS485 Modbus RTU
• Superior Flexible Power: 10 – 40 VDC or 19 – 28 VAC (50-60 Hz)
• DIN Rail Mount (35 mm)
• Removable Terminal Blocks

The ZNET™ model Z-SG provides configuration for the most popular load cells and measurement spans commonly used: 1 mV to 128 mV with a 5 V excitation. This translates to load cell sensitivity of 0.2 mV/V to 25.6 mV/V. The Z-SG has a configurable DC current or voltage output. The Z-SG also has a Digital I/O port that may be used as either a digital input (Tare) or output. The Z-SG completes its unprecedented flexibility by including a standard serial communication protocol, Modbus RTU, via RS485 bus or direct via RS232. The Z-SG may be a Modbus slave. PC Configuration software is available for enhanced operation and Modbus register configuration. LEDs on the front indicate status and power and provide feedback for the Modbus communications. Signal Conditioning flexibility and use made easy from ioSelect.

Modbus RTU Distributed IO Digital Output: ioPro 16DO

16 Digital IO Channel Modbus RTU Output Module by ioSelect

ioPro ioPro 16DO is a 16 open collector (NPN) digital output module. The outputs may be used to drive lamps or external relays when more drive capability is required. The outputs are isolated from the logic and they share a common negative terminal.

• Flexible Modbus-RTU IO Module
• 16 Channels of 24 VDC Output
• LED Status Indication on all Channels
• Operating Temperature: -40˚ to 80˚C
• 1500V RMS Isolation
• Fully Compatible with the ioPak WDL Radio
• Works with the ioPro IOMAP for Simple Mirrored IO

The outputs are read or written to by the Modbus master device such as a PC or PLC. Each output can be individually switched on or off, or all outputs can be set up at the same time by writing a single number to the output register which represents the state of all outputs.

An output watchdog timer can be configured to switch off all the outputs if there has been no communications with the module for up to 255 seconds. A value of 0 seconds will disable this timer and the outputs will remain in the last commanded state (Default).

Distributed I/O Modbus RTU & CANopen-Expansion Made Easy!

Distributed IO for Modbus RTU and CANopen – ZPC Series DAQ by ioSelect

The ZPC Series is a complete line of Distributed I/O Modules with both Modbus RTU and CANopen standard interfaces that do not require any couplers, controllers, or repeaters. All modules have an integrated Modbus RTU/CANopen communications interface at speeds up to 1 Mbps. The ZPC series is the ideal data acquisition and control solution for systems where distributed modules over a wide distance are important.

ZPC Modules can be integrated with third party configurators, mater controllers, network managers, and even in existing legacy Modbus/CAN installations. The advantage of not needing a bus coupler or controller dramatically reduced the cost and complexity for small to medium sized installations.

The ZPC family includes optional interface devices including multi-function controllers, gateway/bridge products, fiber optic interfaces, and repeaters. All products are packaged and designed to work seamlessly with the ZPC I/O Modules.

For more details on this product line, or for specific assistance with your Modbus, Profibus or CANopen applications, contact ioSelect.

Wireless I/O Stack Emissions Monitoring DAQ-Protecting the Environment from Coal Power Gasses

Distributed I/O-Redundant Fiber to Current Repeater Data Acquisition (DAQ)

A utility company needed to upgrade the stack emissions monitoring systems used on their coal fired power plants. The new probes required more power and had more output signals than the previous system. It was important that the new system have built-in redundancy for power and communications, something standard emissions analyzers did not provide. The power company approached a variety of monitoring system providers, but only ioSelect had a system flexible enough to meet their needs.

Distributed Flexible I/O-ioPro

Distributed Flexible I/O-ioPro

• High reliability and overall system availability (Redundant: power to probes; communication links)

• Initially use fiber optic, but have an option for wireless (Radio) if desired in the future

• Make the system easy to use and maintain (minimal training to service personnel)

• Easily expand channels with out running more wire.

Based on these needs, ioSelect developed a system that is now deployed at a number of the utility’s facilities and has been proven to exceed all the utility company’s requirements. The installation consists of two enclosures with mostly ioSelect standard products (ioPro-8AI-I-ISO, ioPro-16DI, ioPro-8AO-I, ioPro-4RO, CommsPak Fiber to 485 Converter, and PowerPak 24VDC Power Supplies), configured and integrated in a unique way. The ioPro IO modules used in the utility’s units have robust 1500V isolation and have been proven to be reliable in these harsh environments.

The ioSelect system has been running efficiently and reliably since installation.  For more details about this application, click here: http://www.ioselect.com/application%20notes/ioselect-redundant-fiber-to-current-repeater.pdf
