Siemens 6ES7234-4HE32-0XB0

Product Description

Function:

Supports 4 analog signal inputs, which can be configured as voltage (±10V, ±5V, 1~5V, etc.) or current (0~20mA, 4~20mA, etc.).

16-bit high resolution, suitable for high-precision measurement scenarios.

Supports RTD and TC temperature sensor input, with cold end compensation function.

Electrical isolation: There is no isolation between channels, but the module is electrically isolated from the backplane bus.

Diagnostic function: Siemens 6ES7234-4HE32-0XB0 supports disconnection detection, over-range alarm, etc. to enhance system reliability.
