tM-P8 - 8-channel Isolation Digital Input Module by ICP DAS
|
|
|
8-channel Isolated Digital Input Module, communicable over RS-485 and Modbus RTU, supports operating temperatures from -25 °C ~ +75 °C
|
|
|
The tM-P8 offers 8 channels for digital input, each of which features photocouple isolation. In addition input can be either sink- or source-type using wire connections and all channels can be used as 16-bit counters. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided.
- Sink- and Source-type Digital Inputs
- Photocouple Isolation
- All Channels Can Be Used As 16-bit Counters
- Dual Watchdog
- Cost-effective
- Wide Operating Temperature Range: -25 °C ~ +75 °C
