More information
The Teracom TSA202 is a dual-channel analog input module for the 1-Wire protocol. It acquires analog signals on two inputs and is suitable for industrial and automation measurement tasks with external sensors.
The inputs support two operating modes: 0 to 20 mA current loop or 0 to 10 V voltage input. The selected mode always applies to both analog input channels simultaneously. In 0 to 20 mA mode, the module can handle standard 4 to 20 mA signals and detect values below 4 mA, for example sensor errors or calibration values.
The analog inputs are functionally isolated from the 1-Wire interface. The analog ground GNDS is separated from the interface-side GND to support signal integrity and protection against ground loops.
- Inputs: AIN1 and AIN2, common analog ground GNDS
- Operating modes: 0 to 20 mA or 0 to 10 V, selected via MODE pin
- Measurement: internal 16 bit ADC, ±1 % accuracy, 0.001 mA/0.001 V resolution
- Isolation: functional isolation 1000 VDC
- Power supply: 4.5 to 5.5 VDC, current consumption 25 mA at 5 VDC
- Enclosure: 120 x 36 x 60 mm, 65 g, IP20
- Environment: -20 to 60 °C, 10 to 90 % relative humidity, non-condensing
- Communication: status LED and firmware update via the 1-Wire interface
The raw values in mA or V can be converted in the master controller using an offset and multiplier. This allows use with suitable sensors for electrical and non-electrical parameters such as liquid level, air pressure, gas concentration or pH.
For installation, a linear topology with UTP or FTP cables is recommended. The total cable length should remain within 30 m. Star topology is intended only as a last resort, with up to four sensors and a maximum total cable length of 10 m.
