The DEM-720 equipment allows to create point-to-point links for the digital transmission of video + data and contact over an optical fiber, up to distances of 25 km (50 km with receiver). Provided with a communication channel compatible with the EIA / TIA / RS-232,422 & 485 standard. Built-in alarm mode, activating the isolated contact on the receiver when the video signal or link is lost. Front LEDs for verification of power supply, links, remote / local contact and data transmission. Plug and Play design that facilitates the start-up of the installation. Digital video transmission allows longer link distances with high image quality. Rack mounting formats for 19 ”3U Chassis (PAWAL) and desktop / DIN Rail. Video Input / output impedance: 75Ω Input / output voltage: 1.2V ppmax Video connector: BNC Pass band: 10Hz - 6MHz Signal to noise ratio:> 60dB Sync error: <5% Differential gain: <2.5% Differential phase: <2 ° C / L gain: <5% Communications Selectable data: RS232 / 422/485 Speed: Up to 250Kbps Data connector: RJ45 RS422 / RS485 termination resistance: 120Ω Contact Input: Dry contact Maximum output voltage: 250V AC / 350V DC Maximum output current: 25 mA Optical characteristics Single mode optical power: -15dBm Single mode reception sensitivity: -34dBm General parameters Power supply: PAWAL 12V ~ 24V AC / DC (± 15%) Consumption: 125 mA / 12V DC Operating temperature: -40 ° C ~ + 74 ° C Storage temperature: -55 ° C ~ + 85C Relative humidity: 95% (non-condensing) MTBF: 100,000 hours Dimensions: 41 x 106 x 84 mm Weight: 230g
