Comadan RR10 Tachometer Relay – Speed Monitoring, 11 Pin

Description

Shaft speed monitoring relay that receives pulses from a proximity sensor or encoder and trips the 1CO 8A@250VAC output when the speed exceeds or falls below the adjustable over-speed and under-speed setpoints. PNP/NPN input, 230VAC auxiliary supply, 11 pin plug-in. Three RPM ranges available to suit different applications from slow conveyors to high-speed spindles. Commonly used for motor over/under-speed protection, conveyor belt speed monitoring, fan and pump speed supervision, and centrifuge safety interlocks.

Note: Requires ZB11 11-pin relay base socket (sold separately). For DIN rail retention, add CMAC Spring Clip. Requires an external proximity sensor or encoder to provide the pulse signal. For pulse train monitoring without speed calculation, see the RT40 pulse continuity timer.

Available RPM ranges:
– RR10-220V-200RPM: 200 RPM PNP/NPN input, 1CO 8A@250VAC, 230VAC
– RR10-220V-2000RPM: 2000 RPM PNP/NPN input, 1CO 8A@250VAC, 230VAC
– RR10-230V-20K: 20K RPM PNP/NPN input, 1CO 8A@250VAC, 230VAC
– RR10-NON-STK: non-standard setup
