AutomationDirect offers three analog CPU models featuring two analog inputs and two outputs with ranges of voltage up to 5 VDC or current up to 20 mA. The modules include two built-in RS-232 and one RS-485 communication ports, and real-time clock and battery backup for internal SRAM. All have four DC inputs, and a choice of four DC sinking, DC sourcing or relay outputs.
UWRTD-NB9 wireless RTD probe/transmitter assembly features a stainless steel probe connected to a polypropylene, water-tight transmitter housing. Shipped ready to install and operate. The assembly is available with 3A-approved thermowells for clean-in-place sanitary applications. Each receiver includes free software to convert a PC into a multi-channel temperature monitor, chart recorder or data logger. Each assembly transmits process and ambient temperature, signal strength and battery status in real time. It’s also FCC/CE-compliant.
Modicon M340 PAC requires no battery, eliminating program loss and maintenance costs during power failure. It comes in a compact 4-in. high x 3.7-in. deep size, and uses high-density 64-point I/O cards only 1.25 in. wide. It uses CANopen networks to reduce field wiring and reduce installation costs. It has 4MB of memory upgradeable to 16 MB and an execution speed of 70K instructions/ms.
C66xx series includes two versions with either Intel Core2 Duo or Core2 Quad processors on a Beckhoff ATX motherboard. C6650 is equipped with two hard drives built into removable frames and an on-board RAID controller to form a RAID 1 system with two mirrored hard drives. Three free PCI and three PCI Express x1 slots are available for plug-in cards with a length of up to 8.3 in. The 1 GB DDR3RAM RAM can be extended to 8 GB.
Opto 22’s Snap PAC programmable automation controllers are the first to offer wireless networking and standard Ethernet networking. This wireless technology is based on the IEEE-802.11 specification with support for a, b, and g networks operating in the license-free 5 GHz (802.11a) and 2.4 GHz (802.11b/g) frequency bands. Snap PAC wireless supports both infrastructure and ad hoc mode.
The new fanless ePC-Series of industrial computers are currently available in three sizes, 15 in., 17 in., and 19 in. All are available with five-wire analog resistive touchscreens and NEMA-sealed, panel-mount front panels and are ideal for installation in harsh environments, especially Class I Division 2 areas. They use an Intel Atom N270 1.6 GHz processor, and are rated for -30 ºC to +85 ºC and up to 150 G (11msec) operation.
Pepperl+Fuchs VisuNet Ethernet-supported HMI system solution is available with IEC approval. It can be used in environments corresponding to Zone 1 (gas) and Zone 21 (dust) as specified in the IEC standard (touchscreens, Zone 22, dust). The distance between components in the hazardous area and the host PC in the safe area can be up to 90 meters.
