3 metering ranges, from 10 rpm. to 20.000 rpm. Adjustable start-up delay, from 0 to 10 seconds. Universal pulse inputs for contact, NPN/PNP sensor, Namur sensor, etc. Selectable latch function. 1-pole relay output. DC supply or AC supplies up to 230 VAC Made in accordance with the and EMC regulations The C-mac® tachometer relay type RR10 can be used for many different kinds of speed monitoring. The relay is available in 3 different metering ranges, calibrated in rpm (revolutions per minute). The relay is supplied with universal pulse inputs, which enables you to use many different types of sensors. In addition, the relay can also deliver the supply voltage to the sensor. You can select, if you want the output relay to release at too high or too low speed. You can also select a latch function, which means the relay will stay deactivated, if the set limit has once been exceeded. The latch is cancelled by disconnection of the latch input or the supply voltage. When the function, where the relay is released at too low speed, is selected, the adjustable time-delay can be used to ensure that the unit, which is monitored, can reach its correct speed, before the module starts monitoring. Common technical data: Supply voltage, AC: Supply frequency: Variable supply: Isolation voltage: Supply, DC: Power consumption: Operating temp.: Humidity: Sensor voltage: NAMUR sensor: NPN / PNP sensor: Contact input: Reaction delay: 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 8,2 VDC, max. 10 mA 24 VDC, max. 10 mA 10 VDC, 2 mA The reaction delay depends on the set value, as the module measures the time between two pulses. Example: At 100 rpm: reaction delay 0,6 sek. At 10000 rpm: reaction delay 6 msek. Minimum pulse time: minimum pulse- and pause time is 0,3 msek. Indications: Green LED: Red LED: Adjustments: Start-up delay: Setpoint: Note: Supply voltage connected Relay aktiv Potentiometer, scale 0-10 sec. Potentiometer, scale 1-20 rpm. The start-up delay is only active when the unit is used for underspeed detection. (pin 7-11 connected) Hysteresis.: 3 % of the set level Temp.coefficient: typ. 0,1% per °C Max. load, relay: 8 A - 250 VAC, ohmic load Selection of function: Pin 11. If the terminal is open, the relay releases, when the speed exceeds the set limit. If terminal 11 and 7 are connected the relay releases, when the speed is lower than the set limit. Latch function: Pin 9. If terminal 9 and 7 are connected, and the relay releases, it will stay released, until 9-7 are disconnected or the supply voltage is interrupted. EMC og safety regulations.

If the sensor has an internal resistance to plus or minus, the module must be ordered for the actual sensor (NPN or PNP). Alternatively you can insert a diode (e.g. 1N4007) in series with the sensor output, as shown in the examples...
