tM-P3R3 - 3-channel Isolation Digital Input and 3-channel Relay Output Module
by ICP DAS
|
|
|
|
3-channel Isolated Digital Input and 3-channel Relay Output Module, communicable over Modbus RTU protocol
|
|
|
The tM-P3R3 provides 3 channels for digital input and 3 channels for relay output, each of which features photocouple 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 an 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.
