Woodward’s TUG 4 Series temperature monitoring devices provide up to 16 PT100 RTD (resistance temperature detector) inputs for temperature measurement and monitoring. Two individually configurable trip levels can be programmed for each sensor input. If a measured temperature exceeds its configured trip levels, alarm and shutdown relays will energize accordingly. An additional relay is provided for indicating a wire break fault.
A two line LC display shows the configured names of the analog measuring inputs. If an alarm occurs, an alarm message is displayed, as well as the value of the input that caused the alarm.
Communication interfaces are available in case measuring values and trip levels need to be transmitted to a PC or PLC system.
