Developed by ICP DAS, WISE (Web Inside, Smart Engine), is a user-friendly yet powerful controller for remote logic control and monitoring in various industrial applications. WISE-7555M is designed with a web site interface allowing users to implement IF-THEN-ELSE control logic on controller with no programming required.

With the integration of the IF-THEN-ELSE rule engine, WISE-7555M provides powerful functions such as I/O Monitoring/Control, Counter, Timer, Schedule, E-mail sending & CGI Command sending for numerous industrial applications. WISE-7555M also supports Modbus TCP and MQTT protocols to make seamless integration with SCADA, IT and IoT (Internet of Things) system.

WISE-7555M is equipped with 8 Dry/wet contact digital input channels and 8 source-type digital output channels. It features optical isolation for 2500 VDC of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present. WISE-7555M follows IEEE 802.3af- compliant Power over Ethernet (PoE) specification. It allows receiving power from PoE enabled network by Ethernet pairs. In additional to this, WISE-7555M also has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easier and total costs of cable and switch are significantly reduced.

  • Runs on browsers, no extra software tool is required.
  • No more programming, Web pages provided for control logic editing.
  • IF-THEN-ELSE logic rules execution ability.
  • Built-in I/O(DI: 8 Channels; DO: 8 Channels)
  • Support I/O Monitoring/Control, Counter, Timer, Email sending and CGI Command sending operations.

  • Modbus TCP Protocol for SCADA System Integration.
  • IEEE 802.3af-compliant Power over Ethernet (PoE).
  • 2-port Ethernet Switch for Daisy-Chain Topology.
  • Support Schedule operation
  • MQTT Protocol for IT & IoT(Internet of Things) System Integration.
