RTD Input Modules suit remote I/O functions.

Press Release Summary:




BusWorks® 966EN Input Modules interface up to 6 RTD or resistance signals directly to Ethernet Modbus/TCP 10/100 network. Each unit accepts universal RTD/resistance inputs with user-selectable ranges for platinum, nickel, or copper RTD sensors and 0-500 ohm signals. Three-way 1,500 Vac isolation between input, network, and power circuits protects against surges and ground loops. Each module supports up to 10 sockets allowing communication with multiple masters.



Original Press Release:



New Ethernet RTD Input Modules are Ideal for Remote I/O Functions at Distributed Sites with Low Point Counts



This new addition to Acromag's BusWorks® 900EN Series directly interfaces RTD temperature sensors from remote sites to a Modbus/TCP network without expensive investments for intelligent controllers.

Wixom, MI: Acromag's new BusWorks® 966EN Input Modules interface up to six RTD or resistance signals directly to an Ethernet Modbus/TCP 10/100 network. These independent I/O devices do not require expensive companion products, such as intelligent controllers and backplanes for PLCs or modular I/O systems, to deliver a more compact and cost-effective solution with very low startup costs. Setup is also faster and easier with embedded web pages allowing configuration using any standard web browser. No other software is required. Priced at only $500 for a four-input unit or $650 for six inputs, they are very economical for applications that need to monitor a small quantity of RTD sensors per site. Each module is only an inch wide with the highest density footprint available for compact mounting on DIN-rails. Power requirements are very flexible, supporting standard 15-36V DC sources instead of proprietary 5V supplies.

Each unit accepts universal RTD/resistance inputs with user selectable ranges for platinum, nickel, or copper RTD sensors and 0-500 ohm signals. The 16-bit sigma-delta A/D converters deliver highly accurate measurements. A built-in RTD sensor break detection feature senses wiring failures and invokes upscale or downscale failsafe output. Three-way 1500V AC isolation between the input, network and power circuits protects against surges and ground loops.

The I/O modules provide an isolated Modbus/TCP 10Base-T/100Base-TX network interface. Each module supports up to 10 sockets allowing communication with multiple masters. Automatic negotiation arbitrates 10/100 Mbps and full/half-duplex communication. Built-in watchdog timers monitor communication problems while self-diagnostic capabilities simplify maintenance and troubleshooting. A failsafe mode ensures outputs are sent to a safe state if a failure occurs.

Many other features ensure dependable operation. An internal microcontroller has integrated non-volatile memory for reliable storage of configuration parameters and can be reprogrammed repeatedly. And to visually confirm proper operation, LEDs indicate power, network activity, and individual channel status. The units are pending CE approvals and UL/cUL Class I Division 2 listing.

Acromag, a multimillion dollar international corporation, has been manufacturing and developing measurement and control products for more than 45 years. They offer a complete line of industrial I/O products including process instruments, signal conditioning equipment, data acquisition boards, distributed I/O systems, and communication devices.
