I/O Module
The ST-MIX12884 SixTRAK Combination I/O Module has 12 discrete inputs, 8 discrete outputs, 8 analog inputs, and 4 analog outputs. Up to 20 modules can be connected to the high-speed I/O bus of the company’s controllers, RTUs, and I/O gateways. The module is vibration and surge resistant, operates in temperatures ranging from -40 to +70°C, and is rated for CE, UL, CSA, and hazardous locations Class 1, Division 2 (Zone 2).

Analog Signal Conditioners
SensorLex signal conditioners include the 8B40/41 analog voltage input module and the 8B39 current output module. In both, clamp circuits on the I/O and power terminals protect against harmful transients, have a high level of immunity to environmental noise, and are suitable for installation in Class I, Division 2 hazardous locations. They withstand temperatures of -40 to +85C and relative humidity range of zero to 95% noncondensing, and meet the requirements of EN61000-6-4 and -6-2. Dataforth; 800/444-7644; www.dataforth.com
RFID Alternative
Visidot automatic identification and data capture system reads assets labeled with standard 2D Data Matrix barcodes or with Visidot colorcodes. As assets pass in front, the reader captures hundreds of labels simultaneously and transmits the information to an image processing system, which decodes the data. Images can be stored in a separate Image Bank. A Site Management System controls the entire process. ImageID; 781/793-9380; www.visidot.com
Analog Input Module Takes All
The PACSystems RX3i Universal Analog module provides eight channels of 24 bit analog inputs, including 30 types of thermocouples, RTDs, resistance, current and voltage inputs. Channels can be individually configured using the company’s Proficy Machine Edition software. Six filter frequencies are individually selectable by channel. It has autocalibration, on-board error-checking, open-circuit detection, and short-circuit detection. GE Fanuc Automation; 717/285-4400; www.ge.com
