(1) Connecting the Input/Output Terminal block
The channels are not insulated from each other. Take care to avoid
short circuits. When measuring two measurement points having a
potential difference, equalize the ground level potential of the object to
be measuredwith that of the module, or use another 2341-20 module.
This prevents unreliable measurements.
The maximum input voltage is INPUT V IN +30 V.
Ensure that the input does not exceed the maximum input
voltage to avoid instrument damage, short-circuiting and
electric shock resulting from heat building.
1. Hold down the button of the terminal
using a flat-blade screwdriver or
similar tool.
2. While holding down the button,
insert an input/output cable into the
lead connection hole.
3. Release the button to lock the cable.
Connect an input/output
cable to the appropriate
terminal.
Make sure the cable length does not exceed 30 m (98 feet). If the
cable is longer than 30 m, measurement may be affected by
external noise or other electromagnetic environment.
