GEFRAN 40T-48 Measurement Accuracy

Official Nominal Accuracy

1. Термопара / RTD Input

±0.2% Full Scale (ФС) ±1 digit

Test condition: Ambient temperature 25℃

2. Linear Analog Input (мВ, 0~10 В, 0/4~20 мА)

±0.2% Full Scale (ФС) ±1 digit

Temperature Drift

When ambient temperature deviates from 25℃:

≤ ±0.01% FS / ℃

Important Supplementary Notes

1. Разрешение: 4-digit LED display, minimum display unit 1 цифра
2. Accuracy only refers to instrument itself, excluding sensor error
3. Alarm actuation accuracy follows measurement accuracy with no additional deviation
4. Ограничение: No PID regulation, only measurement & тревога; no control accuracy index

Practical Example

Range set as 0~200℃:

Maximum instrument measurement error ≈ ±0.4℃ ±1 digit

GEFRAN 40T-48-4-00-RR-0-0-0-0 Конфигурация выхода

Model output segment: …00-RR-0-0-0-0

1. RR = OUT1, OUT2
2. 7th digit `0`: No 3rd output
3. 8th digit `0`: No analog retransmission output
4. 9th digit `0`: No communication interface
5. Onboard Outputs

2 Relay Outputs

Contact form: Нормально открытый (НЕТ)

Рейтинг контактов: 5А / 250ВАК; 5А / 30В постоянного тока (резистивная нагрузка)

Приложение: High/low limit alarm, limit switch signal; can drive small contactors and indicator lights

✅ Feature: Independent alarm outputs; alarm value and mode (high/low limit, deviation alarm, и т. д.) can be configured separately

2. Outputs NOT available on this model
3. ❌ No 4~20mA / 0~10V analog retransmission output (digit = 0, not 2)
4. ❌ No SSR drive voltage output
5. ❌ No RS485 Modbus communication
6. ❌ No NPN/PNP transistor logic output
7. ❌ No PID control output (this unit is only for monitoring & тревога, incapable of temperature regulation)
8. Optional Output Combinations of the Series (for model selection reference)

RR: Dual relay (current model)

РС: OUT1 Relay + OUT2 SSR drive output

SS: Dual SSR drive outputs

Suffix digit `2`: Extra 4~20mA analog retransmission output

Suffix digit `4`: RS485 Modbus RTU interface

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

Уведомление: 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 < заданное значение

3. Deviation Alarm (Positive / 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. Критические ограничения
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 ряд).
6. OUT1 and OUT2 work independently; combination such as high limit on one channel and low limit on the other is supported.
7. Parameter Access Procedure

Long press [F key] для 2 seconds → Enter default password 99

Navigate within `CFG` menu group:

o.1: OUT1 alarm setpoint

o.2: OUT2 alarm setpoint

Select alarm type, hysteresis, latch function and power-up suppression in corresponding submenus
