The IUC-XX-LNT is a microprocessor based integrator with linearizer. It has one analog input, one analog output and a contact (or pulse) output. The contact or pulse output is the integrated output of the analog input. The integration range can be easily adjusted to anything from 0.25 CPH (counts per hour) to 8192 CPH. The integration output can be either a dry contact or a 24 VDC pulse.

Two built-in linearizing functions can be activated via jumpers and the IUC-XX-LNT will then first linearize the input before integrating it. The two functions are Square Root and 1.5 Power. The analog output reflects the linearized input if a linearization has been activated. Otherwise it is a linear follower of the input.
