8-channel RTD input module with wide input ranges

Flexible high-speed I/O control module realizing stable and high-speed operation

Programmable ControllersMELSEC-L seriesNew Product Release No.351E

8 input channels with wider input rangesSingle L60RD8 can measure temperatures of up to 8 channels. With the number of supported channels doubled compared to before (L60MD4-G), space and cost savings can be realized. The input range is expanded to meet the DIN standards, GOST standards, and Pt1000 range in addition to Pt100, JPt100, and Pt50, bringing new application possibilities.

Reduced wiring time with no screw tighteningThe module is equipped with a spring clamp terminal block, which does not require screw tightening. This push-in type terminal block does not require any dedicated wiring tool and significantly reduces the installation time.

Easier calibrationMeasured temperatures can be easily calibrated towards the actual temperature using the sensor calibration function (shift function, 2-point sensor compensation function).

L60RD8

Just push into the terminal block without any tool.

Measured temperature of RTD input module (°C)

The measured temperature of 10.8 to 50.7 (°C) is calibrated to be 10.5 to 50.0 (°C) by digital calculation. A temperature closer to the one input to RTD is obtained.

Gain value before calibration 50.7°C

Offset value before calibration 10.8°C

Calibrated gain value 50.0°C

Calibrated offset value 10.5°C

Fast and stable I/O responseHigh-speed response is realized with the hardware performance asynchronous to the CPU and control bus.

Easy FPGA setup with dedicated configuration tool*2

The design process associated with FPGA (HDL programming, logic synthesis, timing analysis) is no longer required, drastically reducing the development time. The configuration tool is also useful to pre-check the product operation, further reducing the startup time.

Supporting versatile applicationsThe flexible high-speed I/O control module realizes a wide range of controls including speed measurement, adjusted pulse output, ratio setting/distributed output, PWM control, and cam switch control.

LD40PD01

Flexible high-speed I/O control module realizing stable and high-speed operation!

• LD40PD01 is equipped with an external I/O interface and FPGA*1. This feature enables LD40PD01 to perform high-speed control, without being restricted by the CPU scan time and control bus performance. Dedicated configuration tool is also available to pre-check the product operation, further reducing the startup time.

• I/O response is stable as its processing speed only fluctuates in nanoseconds.
