tM-P4A4

4-channel Isolated DI and 4-channel Isolated DO Module

Introduction

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