They use an 18-bit a/d converter for high-resolution measurement. Inputs feature field-programmable selection of nine thermocouple sensors, two standard RTD curves, and six linear-process inputs. Each temperature controller has four independent programmable outputs for heating, cooling, and using alarms. Output options feature standard modules, plus three optional auxiliary power supplies for powering external transmitters, various sensors and other small devices. Digital communications use standard Modbus RTU protocols.
