The Novus N1020 PID controller features advanced performance capability for the most complex and critical applications and 1/32 DIN size for mounting in space-critical applications.

The sophisticated auto-adaptive PID algorithm continuously adjusts the PID parameters for best controlling performance. The programmable input accepts a range of thermocouples, PT100 RTDs or a 0 to 50 mV signal. Two outputs are available - one relay output and one pulse output for interfacing to an SSR for fully-variable control.
