MR 620 Characteristic features: • Digital-analog converter • Converts binary signals into analog signals • Two 16-bit analog outputs to deliver current or also voltage signals as an option • Extend by connecting a maximum of 13 MR620 modules in series Overview of digital Web monitoring modules MR285 Electronic cam controller MR600 Digital Web server MR610 Input-output extension MR620 Digital analog converter Analog-digital converter 2x12-bit input Accessories MR640 Mobile transmission module MR650 Battery unit MR685 Connecting cable Installation The MR620 (digital-analog converter) is latched onto a DIN rail in the switch cabinet. A 10 mm air gap must be left between units to prevent the module overheating. The earth terminals should be connected by the shortest possible route to the central earthing point of the mounting plate. The external Web interface of the MR600 is connected by the 10-pole flat cable supplied to the "ext.Int.IN" 10-pole pin connector on the MR620 module. Each additional MR620 module is connected to the "ext.Int.OUT" connector by the associated 10-pole flat cable. If an MR610 module is used in addition to the MR620 module, the MR620 module must always be connected to the end of this chain. The power supply is 24V DC +/-20% and must be connected for each MR620 module. The MR620 module data lines are interconnected by optocouplers and are therefore potential-free. The analog outputs must be wired with shielded cable and one side of the shielding must be attached to the earth connector. The power must be disconnected before any cable connections are made.
