Connecting the DC inputs of the 800 standard
Use input terminals I1 to I12 of the DC easy800 standard to connect
pushbutton actuators, switches or 3- or 4-wire proximity switches. Given the
high residual current, do not use 2-wire proximity switches.
These DC easy800 standard enable you to read both digital and analog input
signals via the inputs I7 (IA01), I8 (IA02), I11 (IA03) and I12 (IA04).
• Digital input signal voltage range
• I1 to I6, I9, I10.
Signal OFF: 0 to 5 V.
Signal ON: 15 to 28.8 V.
• I7, I8, I11, I12.
Signal OFF: < 8 V.
Signal ON: > 8 V.
• Input current:
• I1 to I6, I9, I10, R1 to R12: 3.3 mA at 24 V
• I7, I8, I11, I12: 2.2 mA at 24°V
￫
The increased capacitance increases the drop out delay by
approx. 40 ms.
￫
Feed the digital inputs from the same 24 V DC power source as
the device.
