The Honeywell UDC3500 universal digital controller packs new powerful features in the popular 1/4 DIN size.

Unmatched application power includes: infrared (IR) configuration interface, three universal analog inputs, two loops of control and two math algorithms. When these are combined with the Accutune III tuning with fuzzy logic overshoot suppression, the result is price/performance leadership.

Application flexibility is assured by the universal analog inputs, universal AC power supply, four digital inputs, a maximum of seven analog and digital outputs, infrared, RS422/485 Modbus RTU or Ethernet 10Base-T TCP/IP Modbus communication protocols, simple configuration plus total field upgrade capability for any optional feature.
