The Siemens Industry Automation Division has developed narrow IO modules with a width of just 25 millimeters (mm) for the Simatic ET 200MP distributed I/O. This means that up to 30 modules can be mounted on a standard mounting rail of 830 mm. The new modules can be combined with the 35-mm modules of the same design which are already established on the market. The new portfolio of 25-mm modules for Simatic ET 200MP includes the following digital input and output modules: DI 16x24VDC BA, DI 32x24VDC BA, DQ 16x24VDC/0.5A BA and DQ 32x24VDC/0.5A BA, as well as the mixed module DI/DQ 16x24VDC/16xDC24V/0.5A BA.

With the same pin assignment for wiring, the circuit and wiring diagrams can be universally used for the two module sizes 25 mm and 35 mm. The new modules also use the easy-to-handle push-in terminal technology. The front connector required for this purpose is supplied together with the module.

The Simatic ET 200MP distributed I/O system features a modular and scalable station design. The IO modules can also be used for centralized automation tasks with the new Simatic S7-1500 controllers. The new 25-mm modules have an extended range of functions as compared to the 35-mm modules – for example with respect to on-delay, parameter assignment or diagnostic options.

Acromag expands their line of versatile USB-configured signal conditioning transmitters to include RTD/resistance and potentiometer/thermistor input signals.

Acromag’s new offerings in the TT230 and TT330 series of process transmitters are designed to deliver flexibility while maintaining optimal performance. These isolated signal conditioners feature high-density mounting on DIN rails, supporting RTD/resistance and potentiometer/thermistor input signals. With a convenient USB connection to a PC, precise configuration using Windows software is simple. Wiring terminals are front-facing and removable for easy connections and maintenance.

“The TT230 and TT330 process transmitter series’ continue to provide greater versatility with our new additions,” explained Don Lupo, process group sales and marketing director. “Whether you need 2-wire or 4-wire transmitters, we can accommodate a wide array of process measurement and control applications.”

Each model accommodates a variety of signal types selected in the configuration software. The TT234 and TT334 models interface 100-100k ohms via potentiometer/slidewire or 100-1M ohms from a thermistor/rheostat. The TT235 and TT335 models accept 100 ohm, 200 ohm, 500 ohm, or 1000ohm platinum RTD; 120 ohm nickle RTD; 10 ohm copper RTD; or 0-450 ohm linear resistance. All units effortlessly convert the input signals to a proportional current output signal of +/-20mA, 0-20mA, or 4-20mA. The TT330 series also allows for +/-10V, +/- 5V, 0-5V, and 0-10V output signals as well. The software also lets you precisely scale input ranges for full resolution. You can then test or calibrate input/output values in the software, too.

TT230 process signal converters have the option of loop-power with a 2-wire connection, or DC-powered with a 3-wire connection. TT330 process signal converters are DC-powered (12-32V) and support a bussed rail power option for primary or redundant power. The rugged design of these thin transmitters feature CE approval as well as: -40 to 80 Degrees C operation, electrical noise immunity, and surge protection. UL/cUL Class 1 Division 2 Zone 2 hazardous location approvals pending. Prices start at $175 (TT230 series) or $220 (TT330 series) for single quantities.

The USB-to-PC connection for software-driven configuration makes setting ranges and calibration easier, more accurate, and very reliable. Many competing units use DIP switches that can only offer coarse range settings, not fine adjustments. Using trim pots can allow fine tuning, but they require far more time to achieve the desirable results. With a USB port, you can digitally set the calibration gain and offset using precision D/A converters whereas DIP switches and pots can change values over time or due to temperature/shock/vibration. These changes can lead to drift and require periodic re-calibration. And once configured, the device’s settings can be archived in a file or uploaded quickly into additional units for rapid cloning in large systems. Later, a device’s USB port enables diagnostic communication using software while a unit configured with DIP dipswitches and pots cannot. Plus, USB-configured devices use fewer mechanical parts which increases long-term reliability.

The Siemens Industry Automation division has developed a new controller for extreme environmental conditions. Siplus S7-1500 has the same performance characteristics as the newest standard controller family Simatic S7-1500 for mid-level and high-end machine and plant automation. Other outstanding features of the new controller Siplus S7-1500 are reliable operation under extreme medial loads such as humidity, corrosive vapors, salts or dusts.In an extended temperature range, the Siplus S7-1500 functions reliably during cold starts as well as in continual operation. This saves energy costs for the user because no additional air conditioning is necessary.

Robust, enhanced modules make it possible to safely use the system everywhere from offshore plants and harsh industrial environments up to applications at extreme altitudes. The new device is protected against condensation and corrosive gasses, as well as aggressive and saline atmospheres. The Siplus S7-1500 controller has the same performance and efficiency characteristics as the Simatic S7-1500, the new standard controller generation from Siemens. Its characteristic features include outstanding system performance and a host of functions integrated as standard, including Motion Control, Security for maximum possible plant security, and Safety for safety applications that are easy to implement. Greater efficiency is represented in particular by the innovative design for simple commissioning and safe operation, the configurable diagnostic functions for the plant status and the integration into the TIA Portal for simple engineering and low project costs.
