Digital Output Board

The Digital Output Board (DOBv2), 24VAC/20-60VDC-Eight (8) channel digital output board each consisting of a 10A @ 120VAC Form C relay, on-board on/off/auto bypass, and Isolated M-Bus w/heartbeat. Up to six (6) can be networked to the ESB.


The TELSEC MP2 is designed to address the monitoring and alarming requirements of critical infrastructure equipment used in Utility, Telecommunications and Cable/Broadband remote facilities. The compact intuitive system will monitor environmental conditions such as temperature, humidity, intrusion, DC power plants, generators, fuel level, energy usage, and other critical systems found in a remote cabinets and shelters.

The MP2 has 32 universal inputs which support monitoring temperature, contact closures or any 0-5 VDC or 4-20 mA sensors. Two RS485 serial ports are available to monitor Modbus RTU enabled devices for trending and alarming. Up to 512 unique Modbus registers can be polled. There are four digital outputs for alarm notification or control such as generator exercise, as well as an Ethernet port for remote communications.

The system features a built-in web server for programming and status monitoring of the site including a historical graphing engine. The alarm logic is programmable with multiple severity levels and all programming is stored in non-volatile memory. The system supports 544 alarm programs. All alarms notifications are sent using SNMP traps and/or email notification.
