8 Digital inputs and 8 Digital Outputs on Modbus RTU
DAT10188
The DAT10188 Modbus RTU Module is a digital I/O device with 8 digital inputs and 8 digital outputs, designed for use in Modbus RTU networks for industrial automation. It allows seamless integration of digital signals with PLCs, SCADA, and other Modbus master devices.
The 8 digital inputs detect ON states between 10 and 30 VDC and OFF states below 3 VDC, with a fast sampling time of 5 ms. The 8 digital outputs are PNP transistor outputs rated for 10–30 VDC, with a maximum load of 500 mA per channel or 1 A per module.
The DAT10188 provides three-way galvanic isolation between inputs, outputs, and power supply, ensuring safe operation and reliable performance in industrial environments.
