Teracom TSC201, 1-Wire isolated current sensor
Teracom TSC201, 1-Wire isolated current sensor
TSC201 is a compact current sensor module with a 1-Wire communication interface and an input range up to 10 A, designed for monitoring both AC and DC currents. It is optimized for use with current transformers (CTs) that provide a 10 A secondary output, enabling the indirect measurement of higher primary currents. The module features a 16-bit ADC for high-resolution measurements and galvanic isolation between the current input and the communication interface, ensuring electrical safety and system protection.
The device is factory calibrated and requires no user adjustment. It can be powered externally with 4 to 5.5 VDC. When used with Teracom controllers, the power supply is delivered through the 1-Wire interface itself. Data update frequency depends on the master device. Teracom controllers typically request sensor data every second, which is close to the maximum practical polling rate for the 1-Wire protocol.
The sensor is enclosed in a compact 2-DIN module housing suitable for mounting in electrical panels and industrial enclosures.
