Interface 4 analog inputs ModBUS
The KET-CAD-104 is a module for the acquisition of 4 voltage or current inputs in the range of ±2.5 VDC, ±10 VDC and ±20 mA with 16 bit resolution. The module's auxiliary power supply can supply all 4 current loops at the same time. With DIP-Switch it is possible to set address, Baud Rate and sampling time for all channels to 240 ms or 480 ms. The KET-CAD-104 provides 1500 Vac input isolation from other low voltage circuits. The module supports RS485 serial communication with ModBUS RTU Slave protocol, maximum 32 nodes, compatible with ModBUS Master KET-RMB-211 and X-Monitor Gateways.
