Analog-digital converter Typ: MR 630 - 1

MR 630 Characteristic features: Analog-digital converter Օ Input module for MR285 Two independent voltage (-10V to +10V) or current inputs (0-20mA) with 12-bit resolution Օ Up to 5 MR630s can be connected Overview of digital Web monitoring modules MR285 Electronic cam controller MR600 Digital Web server MR610 Input-output extension MR620 Digital analog converter MR630 Analog-digital converter 2x12-bit input Accessories MR640 Mobile transmission module MR650 Battery unit MR685 Connecting cable Installation NB: The MR630 must be connected at the end of the external interface chain. The MR630 (analog-digital converter) is latched onto a DIN rail in the switch cabinet. The earth connections and cable shielding should be connected by the shortest route to an earth terminal block provided beside the unit. The optimum discharge of interference to the shielding is obtained by means of the earthed mounting plate and its electrical connection to the DIN carrier rail. The power must be disconnected before any cable connections are made. The external interface (MR600, MR610, MR620) is connected by type MR686 cable to the "external interface IN" or "ext.Int.IN" connector on the module. Each additional module is connected to the "external interface OUT" or "ext.Int.OUT" connector by the same type of cable. The external interface data lines are electrically insulated from each other by optocouplers; they must be of shielded installation and the shielding must be taken to earth at both cable ends. Analog signals must be of shielded installation and one side of the shielding taken to earth. The power supply is 24V DC +/-20% and must be connected individually for each module. > Technische nderungen vorbehalten / Subject to change without prior notice www.micronor.ch size="-1">

Analog-digital converter Typ: MR 630 - 2

MR 630 Status LED The MR630 has 2 status LEDs (see). LED 1 shows whether the power supply is on. LED 2 shows that no data exchange is currently taking place through an MR285. Possible causes: The length of the cable fitted exceeds the safe 300 metre limit, or the MR285 is switched off or data exchange has been interrupted (cable break).
