Retransmission Temperature Controller

The ATR171 Retransmission Temperature Controller is a versatile and robust device designed for precise temperature control in various industrial applications. This dual-input temperature controller can handle inputs from a wide range of sensors, including thermocouples, RTDs, thermistors, as well as voltage (mV) and current signals, making it adaptable to diverse environments.

Key Features

• Retransmission Output: The ATR171 is equipped with an output capable of retransmitting sensor input as either a 0-10V or 4-20mA signal, ensuring compatibility with other control systems and devices.
• Dual Input: The controller supports two input channels, with one channel programmable for both temperature sensors and V/mA process signals, and the second input channel dedicated to temperature sensors. This makes it ideal for differential control applications.
• Triple Set Points: The device can be configured with up to three set points, which can be triggered via a digital input. These set points enable the creation of temperature profiles for applications requiring precise temperature ramping, maintenance, and cooling cycles.
• Flexible Outputs: The ATR171 offers up to four relay outputs, a solid-state output, and an optional Modbus RS485 communication output, providing flexibility in alarm and control configurations.
• User-Friendly Interface: Featuring two 4-digit displays, one for the process variable and the other for the set point, the ATR171 ensures clear and precise monitoring. The controller can be programmed via the front panel keypad or using PC-based software, which also supports high-speed configuration and cloning of multiple units with a memory card.
• Environmental Durability: The ATR171 is designed to withstand challenging industrial conditions, with an IP54 rated front panel (upgradable to IP65 with an optional gasket) and IP30/IP20 rated enclosure and terminal blocks. The device operates reliably in temperatures ranging from 0 to 45 °C and humidity levels between 35% and 95% RH (non-condensing).
• Advanced Control Algorithms: The ATR171 supports ON-OFF control with hysteresis, as well as more advanced PID, PI, and PD control algorithms, with manual or automatic tuning options. Additional features include soft-start functionality, loop break alarms, and double PID control for heating/cooling applications.
• Comprehensive Communication Options: For systems requiring integration with other devices or networks, the ATR171 offers an optional RS485 communication port with Modbus RTU/Slave protocol, enabling seamless data exchange.
• Power Supply Flexibility: The controller can operate across a wide power supply range of 24 to 230V AC/DC with galvanic isolation, ensuring compatibility with various power systems and enhanced safety.
