GEFRAN 40T-48 Measurement Accuracy

Official Nominal Accuracy

1. เทอร์โมคัปเปิ้ล / RTD Input

±0.2% Full Scale (เอฟเอส) ±1 digit

Test condition: Ambient temperature 25℃

2. Linear Analog Input (เอ็มวี, 0~10V, 0/4~20mA)

±0.2% Full Scale (เอฟเอส) ±1 digit

อุณหภูมิดริฟท์

When ambient temperature deviates from 25℃:

≤ ±0.01% FS / ℃

Important Supplementary Notes

1. ปณิธาน: 4-จอแสดงผล LED หลัก, minimum display unit 1 หลัก
2. Accuracy only refers to instrument itself, excluding sensor error
3. Alarm actuation accuracy follows measurement accuracy with no additional deviation
4. ข้อจำกัด: No PID regulation, only measurement & เตือน; no control accuracy index

Practical Example

Range set as 0~200℃:

Maximum instrument measurement error ≈ ±0.4℃ ±1 digit

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.

อันตราย 40T-48-4-00-RR-0-0-0-0 Relay Operation Mode

✅ Both OUT1 and OUT2 relays support custom configuration via front panel

สังเกต: This is a digital alarm indicator without PID control. Relays can only be used as alarm outputs, not temperature control outputs.

1. Configurable Alarm Modes (Independent for two relays)
2. Absolute High Alarm (Hi)

Relay energizes when measured value setpoint

2. Absolute Low Alarm (Lo)

Relay energizes when measured value < จุดกำหนด

3. Deviation Alarm (เชิงบวก / Negative Deviation)

Trigger based on deviation relative to setpoint (commonly used for differential monitoring)

4. Sensor Break Alarm

Relay activates on thermocouple/Pt100 open circuit or signal over-range

2. 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

3. Critical Limitations
4. 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.
5. Cannot be configured as PID on/off control output (40T series is indicator, not PID controller like 400 / 2500 ชุด).
6. OUT1 and OUT2 work independently; combination such as high limit on one channel and low limit on the other is supported.
