Web-Based Monitoring and Control

The ASCO 5510 Thin Web Server is an internet-based thin client application, which provides real-time monitoring and control of ASCO transfer switches and engine generators from anywhere in the world. The TWS also logs critical alarms and analog information.

With an ASCO 5150 Connectivity Module and an ASCO 5220 Power Manager, it brings the power interface to your browser using a secure user name and password. Alarms and event logs are provided through the browser, while simultaneously transmitting an email indicating that an alarm has occurred with one or more transfer switches.

The TWS can be used with ASCO 300, 4000 and 7000 Automatic Transfer Switches that have Accessory 72A or 72E Communication Interface Modules. The unit has One 10/100 base T RJ45 LAN ports, two USB 1.1 ports, two (DB-9 type) RS-232 and two (DB-9 type) RS-232/422/485 ports.
