Programmable digital controller UDC-35

Brodersen UDC-35 Digital panel controller with three output relays. The controller is microprocessor based and fully programmable from the keypad. Controller function: • P, PI, PD, PID regulator with pulse width controlled output relay. •Heating/cooling controller plus alarm relay. • 3 individual on/off controllers. The panel controller operates with the following input signals: • AC/DC voltage. • AC/DC current. • Temperature with Pt-100/500/1000, Ni-100, thermistors and thermo- couples. The temperature measurement is fully linearized by the built-in microprocessor. • Standard process signals. The actual input signal type and measuring range must be specified when the panel controller is ordered. Programmable facilities: • Controller function (P, PI, PD, PID or on/off). • Auto tune. • 1, 2 or 3 setpoints. • Setpoint hysteresis (below or above setpoint). • Alarm point (symmetrical, below or above setpoint). • Alarm point hysteresis. • Input delay (0-10.0 sec.) • Temperature measuring unit (°C or °F). • Scale minimum/maximum. • Decimal point position. • Correction for temperature sensor tolerances. • Display update time (0.2-10.0 sec.). • Output relay mode selection with 4 different output modes. • Delay, output relay 1,2 and 3 individually (0-50.0 sec.). The settings are stored in an EEPROM and accidental change of preprogrammed settings is avoided through the keypad lock facility. 3 output relays with LED indication of energized relay.
