Divelbiss Corporation (www.divelbiss.com) has launched the all-new HEC-HMI Harsh Environment HMI, an addition to its family of Harsh Environment Controllers.
Based on the patented PLC-on-a-Chip technology, the HEC-HMI series controller allows programmable intelligence under lesser ideal conditions thanks to a water-tight enclosure with gland connectors. This standard enclosure is screw and sub-plate mountable, as well as sealed against the environment. The HEC-HMI series is programmed with Divelbiss EZ Ladder software that supports ladder diagram with function block programming.
The HEC-HMI series is offered as a HMI only or a HMI with Programmable Logic Controller (PLC) in the same enclosure. The entire series is available with an extended operating temperature range from -40°C to 80°C and 8VDC to 32VDC input power. A backlit LCD display is also offered in either 4 line by 20 character or 2 line by 16 character configurations. Character heights for the 2×16 and 4×20 options are 0.38” and 0.187”, respectively. Moreover, a total of four programmable indicators and nine pushbutton inputs are also provided. Four of the pushbuttons – in a horizontal row – are labeled as function keys, while the remaining five buttons are arranged in a compass pattern to be used as a joystick input. Network communication is achieved through a CAN port or a second serial communication port that is field configurable for RS323/422/485.
The HEC-HMI model series with integral PLCs integrate these additional features to the HMI only version. I/O includes six 8VDC to32VDC inputs (two are 200kHz high-speed counters) and six digital outputs with four rated to four amps with programmable status monitoring and automatic over-current safety. In addition, there are two analog inputs that can be individually configured to 0-5VDC or 0-20ma as required. Analog is offered in either 10- or 15-bit resolution.
