Wiring Reminder
Relays are passive dry contacts. External power supply is required. The instrument does not supply internal power to contacts; do not connect directly to sensor circuits.
GEFRAN 40T-48-4-00-RR-0-0-0-0 Relay Operation Mode
✅ Both OUT1 and OUT2 relays support custom configuration via front panel
알아채다: This is a digital alarm indicator without PID control. Relays can only be used as alarm outputs, not temperature control outputs.
- Configurable Alarm Modes (Independent for two relays)
- Absolute High Alarm (Hi)
Relay energizes when measured value setpoint
- Absolute Low Alarm (Lo)
Relay energizes when measured value < 설정값
- Deviation Alarm (Positive / Negative Deviation)
Trigger based on deviation relative to setpoint (commonly used for differential monitoring)
- Sensor Break Alarm
Relay activates on thermocouple/Pt100 open circuit or signal over-range
- Adjustable Auxiliary Parameters
Alarm Hysteresis: Prevent relay rapid cycling (chatter)
Alarm Latch: Relay stays energized after alarm trigger; manual panel reset required
Power-up Alarm Suppression: Temporarily disable alarms at startup to avoid false triggering
Contact Logic: Select energized on alarm OR de-energized on alarm
- Critical Limitations
- Hardware contacts are Normally Open dry contacts. Physical hardware cannot be changed to Normally Closed; “de-energized on alarm” is realized purely by software logic.
- Cannot be configured as PID on/off control output (40T series is indicator, not PID controller like 400 / 2500 시리즈).
- OUT1 and OUT2 work independently; combination such as high limit on one channel and low limit on the other is supported.
