Programmable Thermocouple Isolators - TCxxxPW Series

Part Number System: The part number TCxxxPW indicates a slim case, serial number, channel configuration, thermocouple signal, transducer type, and programmability.

Features: The isolators offer 3-port isolation, high accuracy and linearity (0.1% F.S.), low temperature drift (50PPM/°C), low power dissipation, excellent EMC performance, miniUSB communication, programmable input/output range, and high reliability (MTBF > 500,000 hours).

General Description: The TCxxxPW series is designed for industrial automation systems to convert thermocouple input signals into matched analog output signals for DCS/PLC systems. It requires an independent power supply and offers various input/output configurations in a 12.5mm thick case for high-density installations.

Selection Guide: The series includes models for current and voltage outputs with various input signal ranges for different thermocouple types (R, S, K, J, T, B, E, mV). Output signals are programmable for current (4~20mA/0~20mA) and voltage (0~5V/0~10V/1~5V/2~10V).

Electrical Characteristics: The input voltage range is 18~30VDC, with power dissipation ≤0.9W for 1 input 1 output and ≤1.2W for 1 input 2 output or 2 input 2 output. It includes reverse polarity and over-voltage protection.

Transmission Characteristics: The isolators have a zero offset and accuracy of 0.1% F.S., a temperature drift coefficient of 0.0050% F.S./°C, and a response time of less than 0.5 seconds.

Isolation Characteristics: The isolators provide electrical isolation with 2KVAC/3KVDC for 1 minute and an insulation resistance of 100MΩ at 500VDC.

EMC Characteristics: The devices comply with CE CISPR22/EN55022 Class A standards for EMI and various IEC/EN61000 standards for ESD, RS, EFT, and surge protection.

Other Characteristics: Operating temperature range is -25~+71°C, with a transport and storage range of -40~+85°C. The package is a 35mm DIN-rail with IP20 safety class.

Connection: The connection uses dismountable terminals with a cross-section area of 0.5mm² to 2.5mm² and a bare wire length of about 8mm.

Operation Notes: Users should read the manual carefully, avoid using the product in hazardous areas, ensure a 24VDC power supply, and not disassemble the product to maintain explosion protection.

Installation & Disassembly: The device is installed on a DIN35mm standard rail and can be disassembled using a screwdriver to release the card lock.
