Monitoring, Control & Test Solutions for Telecom
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 Digital Output Board provides eight (8) Form “C” relays rated at 10 amps. The relays are energized and de-energized in response to commands sent to the DOB from the TELSEC® ESB and Q3™. A bypass LED, status LED, and bypass switch are associated with each relay. The bypass switch allows manual override of controller commands.
The Digital Output Board microprocessor controls communications with the controller, the bypass switching, the indicators and relays. A TELSEC® ESB and Q3™ will accommodate up to six (6) Digital Output Boards. The Digital Output Board is equipped with easy to wire pull apart terminal strips and can be mounted in 3 inch snaptrack.
