Honeywell UDC 3300 manual Current Output Isolated, Electromechanical Relays One or Two

Design (continued)

Isolation (Functional)

Alarm Outputs

Controller Output Types

Controller Output Algorithms

AC Power: Is electrically isolated from all other inputs and outputs to withstand a HIPOT potential of 1900 Vdc for 2 seconds per Annex K of EN61010-1.

Analog Inputs and Outputs: Are isolated from each other and all other circuits at 850 Vdc for 2 seconds.

Digital Input and Digital Output: Are isolated from all other circuits at 850 Vdc for 2 seconds.

Relay Contacts: With a working of 115/230 Vac, isolated from each other and all other circuits at 345 Vdc for 2 seconds.

One SPDT electromechanical relay.

A second alarm is available using the second control relay. This is not available with Relay Duplex, Position Proportional, or Three Position Step control.

Alarm Relay Contacts Rating

Resistive Load: 5 ampere at 120 Vac or 30 Vdc, 2.5 A at 240 Vac.

Current Output (Isolated)

Range can be set anywhere between 0 to 21 mA, and as direct or reverse action. Resolution: 11 bits for 0 to 21 mA

Accuracy: 0.5 % full scale

Temperature Stability: 0.1 % F.S./°C

Load Resistance: 0 to 1000 ohms

Electromechanical Relays (One or Two)

SPDT contacts. Both Normally Open and Normally Closed contacts are brought out to the rear terminals.

Internally socketed

Resistive Load: 5 amps @ 120 Vac or 30 Vdc, 2.5A at 240 Vac
