Universal Alarm Trip Amplifier with Display - DAT5028

Product Overview

The Universal Alarm Trip Amplifier with Display, model DAT5028, is designed to handle various sensor and signal inputs, including RTD, thermocouples (Tc), millivolt (mV), volt (V), and milliampere (mA) signals. This device features a universal analog input, allowing it to seamlessly process and manage different types of signals. The DAT5028 is equipped with a front panel that includes push-buttons and a 4-digit display, making it easy to configure up to four trip alarms. Each of these alarms can control an output relay, providing reliable signal management and control. The device also supports signal retransmission via an analog output, which can be configured for either voltage or current signals using a convenient dip-switch located on the device’s side.

The DAT5028 is engineered for precision and durability, utilizing an internal 16-bit converter to deliver highly accurate and stable measurements over time and across varying temperatures. The device's robust design includes 1500 Vac isolation across all connections, effectively eliminating ground-loop effects and making it suitable for use in harsh environments.
