Since PVR objective is to complement PLC world with its OMNIA supervision program, RANGER was not conceived to compete with commercial PLCs, but to offer a specialized solution to applications where PLCs are not naturally suited.

RANGER comes in five models, sporting an I/O count from 22 to 58, and a standard set of 3 serial ports individually configurable as RS232 or RS485 at various baud rates.

All RANGER models are based on MC 68HC11, an 8 bit microprocessor made by Motorola, running at 2 MHz addressing 32 K EPROM and 32 K RAM.

The electric characteristics of the I/O are the following.

Digital Input

The digital input section of RANGER is based on a modularity of 8. The digital inputs are electrically insulated from the field by optoisolators, and among them in groups of 4, thus for every 8 inputs two independent common terminals are available.

The inputs sink 7 mA at 24 V, behaving as positive logic. A LED near each input terminal shows the input state.

Digital Output

The digital outputs have a modularity of 8 with one common terminal for every 8 outputs.

Each output can sink 500 mA with positive logic.

Analog Input

Single ended, 12 bits resolution, obtained by an integrating dual slope A/D converter with a strong rejection (normal mode) of line noise, and a conversion time of 40 msec.

Input ranges: 0-5V,1-5V,0-20 mA, 4-20 mA jumper selectable.

Analog Output

Single ended, 8 bit resolution.

Output ranges: 0-5V,1-5V,0-20 mA, 4-20 mA jumper selectable.

Power supply requirements

Voltage: 24VDC (18..30), Current: 0.7 A ( needed to power the logic only. I/O current requirements depend from the number of active I/O present)
