Introduction
The tM-P4A4 provides 4 channels for digital input and 4 channels for digital output, each of which features photocoupler isolation. The tM-P4A4 supports source-type output with short circuit protection, while the input is sink-type. All input channels can be used as 16-bit counters. There are options for configuring power-on and safe digital output values. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided.
