IMO's new i3 controller is claimed to reduce equipment costs, as well as the time for integrating discrete PLC and HMI combinations, by the simple means of combining both functions, plus open fieldbus communications, in a single, easy-to-mount unit.
Available with a combination of Digital and Analogue I/O - including Remote I/O - and integrating thermocouple and PT100 inputs, the i3 controller is suitable for both process control and factory automation applications; especially as it is backed by IMO's three-year warranty.
Measuring just 91.63mm2 by 57.5mm deep, the i3 benefits from several levels of functionality that IMO claims to make it the most flexible and cost-effective in its class. In addition to digital and analogue I/O and integral HMI, the i3 integrates advanced controls such as PlD for process control, PWM for stepper motor control, GSM modem or Ethernet, recipe, alarm, timer, micro SD and high-speed counter functions, all of which are supported by free software.
The HMI capability integrates a 128 x 64 LCD display featuring programmable IP65 (NEMA4) function keys, or high-contrast touch screen 160 x 128 LCD and four programmable function keys; both models provide high-level graphics and text capabilities. In addition, the control capabilities provided by the unit's standard analogue (four inputs, two outputs) and digital (24 inputs, 16 outputs) I/O are expandable by interfacing to IMO iOS remote I/O modules. This facility provides extended control capabilities and delivers greater flexibility in system design.
In the area of communications, the i3 is fully featured again, offering widely used Ethernet communications and the facility for two multi-function serial communications ports that can be used for programming, expansion I/O, and ancillary devices such as printers.
Finally, there is an optional GSM modem or Ethernet port for higher-level communications with servers or PCs. Functions of the modem include networking via Ethernet and remote data collection via GPRS, as well as SMS messages, making the i3 a powerful alarm monitor for unmanned outstations.
In addition to its extensive control, monitoring and communication capabilities, the i3 offers the benefit of reduced installation time, as a result of its innovative case design. This allows either panel (IP65) or DIN rail mounting, which gives users flexibility in mounting and positioning the controller.
