Module RS-485 DCON & Modbus 3 kênh đầu vào số (DI) + 3 kênh đầu ra Relay ICP DAS tM-P3R3 CR
The tM-P3R3/tM-PD3R3 provides 3 channels for digital input and 3 channels for relay output, each of which features photocoupler isolation. All output channels are form A type relays, while input is based on sink- or souce-type using a wire connecion. 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.
