The HE693RTD720 module by Horner Electric is designed for accurate temperature measurement, functioning as an analog input module. Each of its six channels is customizable, allowing users to select from several sensor types, including Pt100, Pt1000, and Cu10 RTDs.
Key features include LED indicators that signify the status of each channel and signal faults when they occur. The device typically draws 250 mA from the backplane, making it efficient in power utilization. With an input impedance exceeding 1000 Megohms, this module enhances measurement reliability.
It supports various sensor wiring setups: 2-wire, 3-wire, and 4-wire configurations, providing flexibility for installation. The sensor excitation current stands at a nominal rate of 250 µA. Accuracy levels are within ±0.5 °C typically, with a resolution capability of 0.1 °C, enabling precise readings under various conditions.
Furthermore, the HE693RTD720 module features substantial isolation, with both channel-to-backplane and channel-to-channel isolation rated at 1500 VDC. This aspect enhances the device's robustness in electrical environments by preventing cross-talk between inputs. The presence of configurable alarms for each channel adds an additional safety measure, allowing users to set predefined thresholds for monitoring.
