Dwyer Series 16G, 8G, & 4G Temperature/Process Loop Controllers

Product Overview

The Dwyer Series 16G, 8G, and 4G Temperature/Process Loop Controllers are designed for precise monitoring and control of temperature or process conditions. These versatile controllers support dual loop control using various methods, including on/off, auto-tune or self-tune PID, fuzzy logic, and manual control. They are ideal for applications such as oven control, packaging equipment, and parts washers.

Key Features

• Control Methods: On/off, PID, fuzzy logic, or manual output control.
• Versatile Programming: Supports constant, sloped, program (ramp/soak), or remote set point control.
• Connectivity: RS-485 interface with Modbus ASCII/RTU protocol for easy integration with PLCs or data control systems.
• Hardware: Features two primary control outputs and two secondary/alarm relay outputs.
• Durability: Front panel is rated IP66 for protection against dust and water ingress.

Technical Specifications

• Inputs: Thermocouple, RTD, DC voltages, or DC current.
• Display: Dual 4-digit LCD (orange for process value, green for set point).
• Power Requirements: 100-240 VAC, 50/60 Hz (optional 24 VDC available).
• Operating Temperature: 32 to 122°F (0 to 50°C).
• Control Output Ratings: Relay (SPST, 5 A @ 250 VAC), Voltage pulse (12 V), Current (4-20 mA), or Linear voltage (0-10 V).
• Alarm Relay Ratings: 3 A @ 250 VAC resistive.
• Memory: Nonvolatile memory for configuration retention.

Installation and Operation

The controllers are available in three standard DIN sizes (1/16, 1/8, and 1/4 DIN) to suit various panel mounting requirements. Configuration can be performed via the front panel interface or through the optional configuration software. Ensure the device is installed in an environment within the specified operating temperature range to maintain accuracy and longevity. The front panel IP66 rating ensures reliable operation in demanding industrial environments.
