Overview
IOMod HT is a stand-alone Modbus (RTU), IEC 60870-5-103 and IEC 60870-5-101 wall mounted temperature and humidity sensor device. Designed to measure indoor room or cabinet temperature and humidity with high accuracy, IOMod HT can be used for numerous applications where user requires temperature and humidity monitoring. IOMod HT also can be used as thermostat that controls relay outputs according to user configuration on humidity and temperature limits.
IOMod HT is an ideal solution for such applications as data acquisition, observation, control, process monitoring, testing and remote measurement. It is controlled over Modbus RTU, IEC 60870-5-103 or IEC 60870-5-101 protocol, and can be connected in parallel with other Modbus RTU, IEC 60870-5-103 or IEC 60870-5-101 equipment in a multi-drop installation scheme as in any SCADA system or monitoring platform.
When using IOMod HT with WCC Lite gateway it is possible to monitor temperature, humidity, relay status, also control relays and their settings 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.
