My Part Number:
Part Number: 750-498
Manufacturer Code: 750-498
Multiples of: 1 | Minimum Order: 1
8-channel analog input - Thermocouple; Adjustable
The 750-498 I/O Module measures either voltages (mV) in the field or analyzes thermocouples.
Depending on the sensor selection for the respective I/O module, the voltage value is output directly or converted into the respective temperature value.
Based on the measured values supplied by the thermocouple and the cold junction temperature, the I/O module determines the corresponding temperature at the measurement point of the thermocouple used.
The I/O module has eight input channels, providing a direct connection from thermocouples to 2-wire sensors.
The field level and the system level are electrically isolated from one another.
Number of analog inputs: 8
Total number of channels (module): 8
Signal type: Thermocouple, Low voltages
Signal type: Yes
Sensor connection: 8 x (2-wire)
Data width: 8 x 16-bit data; 8 x 8-bit control/status (optional)
Resolution: 0.1 °C
Conversion time: ≤100 ms (per channel), activated notch filter; ≤50 ms (per channel), deactivated notch filter
Measurement error (25 °C): with cold junction compensation: ≤ ±1 K (type E, N, K, T, J) at ≥-50 °C; ≤ ±2 K (type S, R, C) at ≥100 °C; ≤ ±3 K (type B) at ≥350 °C;(Please find additional measurement error information in the manual.)
Temperature error (max.) of the upper-range value: 0.05%/K
Temperature coefficient: Type K: ±0.05 K/K of the upper-range value; Voltage measurements: ±50 ppm/K of the upper-range value
Sensor types: Type K, J, B, E, N, R, S, T, C; Voltage measurement: ±30 mV; ±60 mV; ±120 mV; ±240 mV
Cold junction compensation: Module-internal based on a cold junction temperature measurement
Configuration options: WAGO-I/O-CHECK, CODESYS Library, e!COCKPIT
Supply voltage (system): 5 VDC; via data contacts
Current consumption (5 V system supply): 100mA
Supply voltage (field): 24 VDC (-25 … +30 %); via power jumper contacts (power supply via blade contact; transmission via spring contact)
Isolation: 500 V system/field
Indicators: LED (1-8) green: Status TC 1 … TC 8; LED (9-16) red: Error TC 1 … TC 8
Number of incoming power jumper contacts: 2
Number of outgoing power jumper contacts: 2
