The R302 Modbus mixed signal remote terminal unit is ideal for demanding field and industrial relay-based applications.
"The complete integration of common industrial control and user interfaces as an integrated, low-cost solution allows process and system control engineers to meet today's reduced project budgets without eliminating features".
"The additional recently added Modbus Communications Software capability makes the Gazelle an ideal solution in applications where integration of intelligent I/O is desired.
This new enhancement is also available on R2 Controls' other standard embedded controller products, including the Gazelle-CP, the Impala and the Bongo microcontrollers".
The R101 Gazelle includes a rich combination of industrial I/O interfaces including 30 digital I/O lines with high-current sinking/sourcing capability and input protection, eight 12bit high-speed analogue inputs, two 12bit analogue outputs, four16bit timer/counters, two comparators, and four PWM/edge detectors.
The Gazelle also includes two RS232 serial ports (one may be configured for RS485), real-time clock, watchdog timer, and expansion port capability using standard protocols such as SPI, SMBus and I2C.
The standard R101 Gazelle is packaged in a metal enclosure with a 4 x 20 LCD (with optional backlight) and 2 x 5 tactile keypad.
The industrial I/O is accessed via Phoenix-style screw terminals and a standard DB9 serial connector.
The Gazelle requires 9-30V DC power to operate.
The Gazelle includes 64Kbyte of program memory for data storage requirements.
Up to 8Mbyte of Flash memory may be provided through the R2 Controls R203 Flash expansion board.
The R401 development kit is available to facilitate rapid end-user adaptation of the Gazelle.
R2 Controls also provides telephone technical support to aid customers during project development and deployment.
The R101 Gazelle costs US $299 (one-off) and is available for immediate delivery.
