DESCRIPTIONAPPLICATIONS

The Series 16G, 8G, & 4G Temperature/Process Loop Controllers allow for monitoring and control of temperature or process conditions. The controller features two independent control outputs for dual loop control using on/off, auto-tune or self-tune PID, fuzzy logic, or manual control methods. RS-485 interface is included with Modbus® communication

protocol, for easy bench-top conguration or integration with a PLC or

data control system.

Inputs Thermocouple, RTD, DC voltages or DC current.

Display Process value: 4 digit, 0.47˝ H (12 mm), orange LCD; Set point value: 4 digit, 0.47˝ H (12 mm), green LCD.

Accuracy ±1.8°F plus ±0.3% of span (±1°C plus ±0.3% of span) at 77°F (25°C) after 20 minutes warm up.

Memory Backup Nonvolatile memory.

0-10 V.

Communication RS-485 Modbus

Weight 9 oz (255g).

Compliance CE, cULus.

ASCII/RTU communication protocol.
