I/O and terminal bocks appear healthy

This month’s roundup on I/O and terminal blocks demonstrates that the industry seems to be recuperating, product development money is flowing, and companies are getting competitive again.

WE PRESENTLY see a wide range of I/O and interfaces for everything from Ethernet and wireless to Profibus, ArcNet, and Modbus. On the terminal block and connector side, innovations and enhancements prevail.

Other than a new emphasis on wireless and Ethernet connections, we don’t see any hard trends in I/O, connectors or terminal blocks. Instead, now that companies are recovering from their economic doldrums, we’re seeing a healthy mix of products of all types coming down the new product chute.

PSD14PSD14 Series 14-W, DC-DC, power-over-Ethernet splitter provides 12.5 W from standard IEEE 802.3af power sourcing equipment (PSE). The splitter is a power supply that can be mounted next to an Ethernet device, and is compliant with IEEE 802.3af standards. Typical applications include IP telephones, wireless network access points, Bluetooth access points, security cameras, and IP print servers. More info at controlglobal.com.

WAN IA wireless WAN cellular router provides secure cellular GSM or CDMA connections for reliable primary and backup network connectivity to industrial automation devices such as SCADA devices, PLCs, and RTUs. It has industrial hardware/software components including a terminal block for power, DIN rail mounting, Class 1, Division 2 certification and Modbus protocol support. More info at controlglobal.com. Digi International; 877/912-3444; www.digi.com

ET-DS-1NETio  family of I/O and wireless communications products carries data from serial and IP devices along with analog and discrete signals. It supports direct protocol addressability of connected I/O from a library of industrial protocols, including Modbus Rtu, Modbus TCP, DNP3 or EtherNet/IP. Wireless expansion modules can be as far as 1,000 feet away. Microwave Data Systems; 585/241-5539; www.microwavedata.com

Models ET-DS-1 and ET-SDS-1 industrial, serial-to-Ethernet device servers offer real-time secure performance including an auto-detecting 10/100 RJ45 Ethernet port and a universal EIA-RS232/422/485 serial port for serial data tunneling across an IP network. Both have back to back (paired mode) operation, port buffering, and IPv6 support. More info at controlglobal.com. Sixnet; 518/877-5173; www.sixnetio.com

Unnamed M12 Ethernet plug connectors are available as overmolded cordsets, field-wireable, and panel-feed-through connectors. This Ethernet connection system is IP67 rated for harsh environments and meets CAT5 requirements of 100 Mbit/s.  Phoenix Contact; 800/322-3225; www.phoenixcon.com

VAZ-2T1-FK AS-interface, flat-to-round-cable converter can be used in narrow and low-profile cable channels and other space-critical locations. In most applications, installation takes less than a minute. The converter is suitable for use where AS-interface and 24 VDC external power need to be on one M12 connector, while drives are with motor starters.

USB22 series of network interface modules provide connectivity between desktop or laptop computers and peripherals. It includes a high-speed microcontroller that transfers data between Arcnet and USB. It has up to 128 Kbytes of Arcnet receiver buffering to handle reception of broadcast messages or monitoring networks with high traffic levels. More info at controlglobal.com.

Emerald-MM-8P PC/104 serial port module has eight multi-protocol serial ports on one PC/104 module with software configurability. The board works in PC/104-expandable embedded computer systems running Linux, Windows, QnX, VxWorks, and DOS. Each of the serial ports can be individually selected for RS-232, RS-422, or RS-485 (both local echo and no echo) under software control. More info at controlglobal.com.

GracePort  D3-Series interface gives users a convenient way to temporarily connect to a Profibus network without opening the control panel door. It supports 12-MB data transfer speed, and includes integral end-of-network termination resistors and switch. This let users install a Profibus network tap anywhere along the Profibus cable run.

Enhancements to the Net Concentrator System process control and distributed I/O network include Modbus RTU (RS-485) communications. With Modbus, the concentrator is able to use twisted-pair wiring, Ethernet, wireless, fiber-optic, and telephone/modem data links to send monitoring and control signals over rugged, long-distance, normally impassable, and hazardous environments.
