4-20mA Controller with Modbus
This controller has been replaced by the ATR244. A newer better and lower cost contoller.
The ATR243 is a versatile 4-20 mA temperature controller with Modbus capability, designed for precise analog control in various process applications. With a 4-20 mA control output and up to three relays, the ATR243 offers exceptional flexibility, making it an ideal choice for controlling any loop. The inclusion of a digital input further enhances its suitability for complex control tasks.
The ATR243 accepts a wide range of sensor inputs, including 4-20 mA, 0-20 mA, 0-10 V, 0-40 mV, thermocouples, RTDs, thermistors, and potentiometers. The controller features dual 4-digit displays: one for the process variable and the other for the set point, allowing for easy monitoring and adjustment.
The ATR243 provides robust control options with one relay and a solid-state output. It supports various control modes, including on-off control, proportional control, proportional-integral (PI) control, and proportional-integral-derivative (PID) control. These control modes can be configured manually or with the convenience of auto-tuning.
With a compact 1/16 DIN standard (48 x 48 mm) design, the ATR243 fits neatly into panel mounts and can withstand harsh environmental conditions up to IP65 with the optional gasket. This makes it a durable choice for demanding industrial environments.
Programming the ATR243 is straightforward, whether using the front panel keypad or PC-based software. The ability to clone multiple units using a memory card enables quick and efficient configuration, while the PC software also supports monitoring multiple controllers. The analog outputs (0-20 mA, 4-20 mA, and 0-10 V) can be used for control or retransmission of the input signal, offering additional versatility.
