The 2500-TAP Remote I/O Network Tap is specially design for attaching trunkline and dropline sections to create 2500 Series® remote I/O networks.  These taps use an impedance-controlled design for highest noise immunity and include built-in termination resistance which can be easily switched in- or out- of the circuit using a toggle switch.  They also include an electrical noise bleed path to chassis ground which can improve the noise immunity of your network.
