MX460B-R Frequency / Counter Module

Up to four (4) digital inputs may be connected to the MX460B-R, to measure digital pulses up to 1 MHz (speed, torque, angle position, displacement, PWM in general). CX23-R/eDAQXR support is limited in the following aspects. Math functions are not supported. Interactive zeroing of the “crank shaft” sensors is not supported.

You can connect up to four transducers to the frequency measuring amplifier MX460B-R. Transducers are connected via a 14‐pin ODU device socket. All measuring channels are electrically isolated from one another and from the mains. When using the adjustable transducer excitation, electrical isolation from the supply voltage of the amplifier is not required.

The MX460B can supply transducer excitation voltage at a constant DC voltage of 5 to 24 volts. Always check encoder data sheet for maximum supply voltage. Supplying 12-volt transducer power to a 5-volt encoder may damage it.

The measurement channels are electrically isolated from the power supply and the interfaces. When TEDS or T-ID is used, the measurement channel is automatically parameterized after connection.
