Input Signal • Type: Thermocouple (T/C) millivolt (mV) input.
• Compatible Types: Typically J, K, T, E, R, S, B, N (user-selectable via DIP switches or configuration).
• Cold Junction Compensation (CJC): Integrated for accurate temperature measurement.
Output Signal • Type: Analog DC Current
• Standard Range: 4 to 20 mA DC (isolated, linear with temperature)
• Load Resistance: Typically 0-550 Ω
Isolation • Type: 3-way Isolation (Tri-port) between Input, Output, and Power Supply circuits.
• Isolation Voltage: 1500 V AC for 1 minute.
Power Supply • Voltage Range: 24 V DC (standard, e.g., 20-55 V DC range)
• Power Consumption: Approx. 1.8 W (typical)
Accuracy • Overall Accuracy: Typically ±0.1% of span (includes input measurement, CJC, and output conversion accuracy).
Ambient Temperature Effect • Span: Typically < ±0.015% / °C
• Zero: Typically < ±0.015% / °C
Ambient Operating Temperature • -20 to +70 °C (-4 to 158 °F)
Status Indication LED for power status.
Connections Removable screw terminal block for easy wiring.
Certifications CE (EMC Directive & Low Voltage Directive), cULus listed (likely).
Configuration Typically configured via internal DIP switches to select the thermocouple type, temperature range, and output behavior.
