The UPD Series universal pulse divider accepts pulse signals from devices such as electric meters and flow sensors, rescales these pulses, and provides an isolated pulse output. This allows the receiving devices to monitor higher frequencies than they are able to accept directly. The UPD-2 provides two separate channels and the UPD-4 provides four channels. The output pulse signal is optically isolated from the input signal and each channel is isolated from the others. The pulse dividers are proven performers in building automation applications.
