Pulse divider/preselection RD53 - 1

Pulse divider/preselection relay RD53 Preselection relay / pulse divider Digital adjustment between 2 and 999 Pulse inputs for contact, NAMUR or NPN transistor. Transistor output for connection to “slave module” 1-pole relay output DC supply or AC supplies up to 230 VAC Made in accordance with the C€ and EMC regulations C-mac® module type RD53 is a digital pulse counter module, selectable as pulse divider or preselection relay. The pulse inputs can be activated from a mechanical contact, a transistor or a NAMUR sensor, and the reset input can be activated from a mechanical contact or a transistor. The unit is supplied with a “slave” transistor output, in this way several units can be connected to the same pulse sensor. Max. load, relay: 8 A - 250 VAC, ohmic load EMC og safety regulations. Emmision: EN 50 081 - 1 Approvals: The units are produced in accordance with the Common technical data: Functional diagram: (selector switch set on 3) Supply voltage, AC: Supply frequency: Variable supply: Isolation voltage: Supply, DC: Power consumption: Operating temp.: Humidity: Counter inputs: NAMUR input: Contact/transistor: Reset input: Counter output: Minimum pulse time: 24, 115 and 230 VAC +/- 10% 40-70 Hz 12-50 VDC or 48-250 VDC Supply - internal - output: 3.75 kV 24 VDC +/- 10% Note: With this DC supply there is no galvanic isolation between the supply and internal electronics. 2,5 VA -20°C to +60°C 0 - 90% RH, non-condensing pins 5-6-7 pins 6-7, pin 6 positive, pin 5 and 7 connected together. pins 5 and 7, pin 5 positive. pins 7-8, pin 8 positive. pins 7-11, pin 11 positive. If the same sensor is used for several units, pin 7 on all units are connected together, pin 11 on the first unit is connected to pin 5 on the next, etc. minimum pulse- and pause time is 15 msec. x-yyy = supply voltage: 0-024: 24 VDC Indications: Green LED: Supply voltage connected Adjustments: 3-digit digital switch Selection of function: pins 7-9. pins 7-9 open: Preselection relay pins 7-9 connected: Pulse dividing relay.
