IOMod 4RTD – industrial 4 temperature sensors module

Overview

IOMod 4RTD is a stand-alone Modbus RTU, IEC 60870-5-101 and IEC60870-5-103 temperature sensor device. Designed to measure indoor thermal statistics over a wide temperature range with high accuracy and repeatability even after frequent heating and cooling cycles. Equipped with 4 temperature measuring channels to enable temperature reading with default configuration.

IOMod 4RTD is an ideal solution for such applications as data acquisition, observation, process monitoring, testing and measurement remotely where high precision over a wide temperature range is needed. Further possible applications include plastics processing, microelectronics, textile processing, as well as numerous other.

IOMod 4RTD is Modbus  RTU, IEC 60870-5-101 or IEC60870-5-103 protocol compatible, and can be connected in parallel with other equipment in a multi-drop installation scheme such as any SCADA system.

When using IOMod 4RTD with WCC Lite gateway, it is possible to monitor temperature (using 4 different sensors) over Ethernet LAN’s or 3G/4G(LTE)/GSM/GPRS networks. It is a powerful solution for remote monitoring and control, alarm management and data logging of I/O’s on CloudIndustries.eu cloud platform.
