Loads with Large Surge Currents (E2E-X@T@)
If a load with a large surge current is connected, such as a relay, lamp, or motor, the surge current may cause the load short-circuit protection
circuit to operate, resulting in operating errors.
● Mounting
Tightening Force
Do not tighten the nut with excessive force.
A washer must be used with the nut.
Note: 1. The allowable tightening strength depends on the distance from the
Connecting a DC 2-Wire Proximity Sensor to a PLC (Programmable Controller)
Required Conditions
Connection to a PLC is possible if the specifications of the PLC and the Proximity Sensor satisfy the following
conditions. (The meanings of the symbols are given at the right.)
1. The ON voltage of the PLC and the residual voltage of the Proximity Sensor must satisfy the following.
2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the following.
3. The ON current of the PLC and the control output of the Proximity Sensor must satisfy the following.
Example
In this example, the above conditions are checked when the PLC Unit is the C200H-ID212, the Proximity
Sensor is the E2E-X7D1-N, and the power supply voltage is 24 V.
