WISE-7504M is a multi-function module with 4-channel analog inputs, 4-channel analog outputs and 4-channel digital inputs module. WISE-7540M provides multiple programmable analog inputs, and analog outputs. Each of its analog inputs can configure a proper range of 240 Vrms high voltage protection. WISE-7504M follows IEEE 802.3af-compliant Power over Ethernet (PoE) specification, allowing it to receive power from PoE enabled network by Ethernet pairs. In additional to this, WISE-7504M is equipped with two-port ethernet switch to implement daisy-chain topology; reducing the cost and allowing easy cabling. By integrating with IF-THEN-ELSE rule engine, WISE-7504M provides more powerful functions such as I/O Moniitoring/Control, Counter, Timer, Schedule, E-mail sending & CGI Command sending for use in various industrial applications. WISE-7504M also supports Modbus TCP and MQTT protocol to make seamless integration with SCADA, IT and IoT (Internet of Things) system.
