How Many 2-Wire DC Proximity Sensors Can Be Connected To The Input Side Of B7AP Power Couplers?
- Power Supplied to One Side
Up to ten Sensors can be connected if power is supplied only to B7AP-S1 (Stationary Units).
1-1. Connect B7A Input Unit to the B7AP-M1 (Moving Units).
Output current from Moving Unit: 38 mA (output voltage: 12 VDC)
Input current per B7A Input Unit: 3.8 mA
Given the conditions above, up to ten inputs can be used.
1-2. The output current of 38 mA from Moving Units do not include the current consumed for B7A Input Units itself.
- Power Supplied to Both Sides
Up to 16 Sensors can be connected if power is supplied to both sides of the B7AP-S1 and B7AP-M1. In this case, a 2-wire AC Sensor or Programmable Controllers can also be connected.
Power and Transmission Signal: Power Supplied to One Side
Transmission Signal Only: Power Supplied to Both Sides
