The LCN-IVH is used to multiply the I connection on a module. In this way, several sensors can be operated on an intelligent module. The connection can be extended to up to 50 m using the screw terminals with IY(ST)Y 2x2x0.8 mmØ. The LCN-IVH can alternatively be used as a pulse counting input for fast signals (max. 500 Hz, e.g. wind sensor). As an I connection extension and duplication, it has no active function. As a pulse counting input, it makes its count value available in the module. This can be evaluated via the switching thresholds. The LCN-IVH is used to extend the I connection from the distribution. In this way, sensors for the I connection (e.g. temperature, remote control) can be installed decentrally.
