FBT RS-485 industrial IO series supports the most commonly used I/O data acquisition protocols, which can be matched with various types of sensors, and is widely used in fire fighting, electric power, water supply, petrochemical, intelligent agriculture and other scenarios.FBT serial RS-485 uses the standard Modbus RTU/ASCII protocol, which can be easily interfaced with the SCADA system to upload on-site sensor data.
The FBTDI16RM utilizes the standard Modbus RTU slave communication protocol, allowing remote data acquisition via the RS485 bus, which can support up to 250 devices.
FBTDI16RM is a 16-channel digital input (DI) RS485 data acquisition module. 16-channel DI supports dry contact or digital signal input, wet node support up to DC60V, each input channel has a 200HZ counter.

application connection

  • network topology

RS485 bus access to this device, should be in line with the RS485 bus wiring specification, using a hand in hand network topology to connect with other devices in the system, and at the end of the bus to join the matching resistance of about 120 ohms (as shown in the ideal connection diagram below). However, in the actual project, is in accordance with the actual connection diagram below for wiring, the figure D for the RS485 bus to the length of the branch line of the device, the length of D is strongly recommended to be less than 0.5 meters

Actual connection diagram

 

  • wiring terminal

DI.COM+ Dry Node Input Common
DI1 to DI16 digital signal inputs
DI.COM- Wet Node Input Common
PWR (2-wire) Connects to positive and negative polarity of power supply, regardless of polarity
A+ RS485 signal A
B- RS485 signal B
NC Not Connected

  • LED indication

PWR Power indicator, always on when power is normal
COM communication indicator, the indicator is on when the serial port sends and receives data; however, when the RS485 bus fails or the serial port attributes are set incorrectly, the indicator will flash, the flash cycle is about 2 seconds.
DI1 to DI16 switching input status indicator: when the light is on, the corresponding signal is 1; when the light is off, the corresponding signal is 0

  • Sensor connection method

The FBTDI16RM supports wet and dry node wiring, and the module wiring is shown with each DI channel wired independently and sharing DI.COM terminals.
