Overview
IOMod 8DI8DO is a stand-alone Modbus (RTU), IEC 60870-5-101, and IEC 60870-5-103 digital input and digital output controller. Designed to achieve a high technological look and compact fit on DIN rail (EN 60715), IOMod 8DI8DO is used for industrial applications where digital signaling is used and robust communication is essential.
IOMod 8DI8DO is an ideal solution for applications such as data acquisition, observation, control, process monitoring, testing, and remote measurement. It is controlled over Modbus, IEC 60870-5-101 or IEC 60870-5-103 protocol, and can be connected in parallel with other Modbus, IEC 60870-5-101 or IEC 60870-5-103 equipment in a multi-drop installation scheme as in any SCADA system.
When using IOMod 8DI8DO with a WCC Lite gateway it is possible to monitor/control the I/O signals over Ethernet LANs 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.
