The tZT-P4C4 provides 4 channels for digital input and 4 channels for digital output, each of which features photocouple isolation. The tZT-P4C4 supports sink-type output with short circuit protection, while input is source-type. All input channels can be used a 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. The tZT series products of ICP DAS USA have the advantage of low cost and low power consumption of ZigBee. Provide wireless communication capability up to 300 meters (LOS) standard transmission distance. Coupled with the dynamic mesh network, users can easily catch DIO data in difficult-to-wire environments.
