Supported Input Modules

Specifically for use with the 10-CH, Medium-Speed Universal Input Module (MX110-

UNV-M10).

Note

The plate with clamp terminals for current is specifically for DC current measurement. When the

plate with clamp terminals for current is attached, measurement can no longer be made of DC

voltage, thermocouples, RTDs, or DI.

Attaching the Terminal Plate With the /NC option, begin from step 3. 1. Loosen the terminal cover attachment screw for the 10-CH Medium-Speed Universal Input Module, then firmly flip over the terminal cover in the direction of the arrow in the figure below and remove it. 2. Loosen the attachment screw of plate, then remove the terminal plate. 3. Attach the plate with clamp terminals for current, then fasten with the screw. 4.

General Precautions When Wiring the Signal Wires WARNING • To prevent the possibility of electric shock when wiring, confirm that the power supply source and the signal source are turned OFF. After making the connections, secure the terminal cover and do not touch the terminals with your hands. • For signal wires on which voltage exceeding 30 VAC/60 VDC is applied relative to the ground potential or between signals, use reinforced (double) insulation wires.

Notes on Measurement Shunt resistance for current measurement is built in. Measurements are taken as DC voltage values in the DC voltage range. When displaying current values, convert voltage values to current values by using scaling or other means. Current value [A] = voltage value [V] / shunt resistance value [Ω] Main Specifications Style number: No.
