Chapter 1 product introduction
One Summary
MB16DI16RO 16The circuit switch input acquisition module and the 16-way relay output module can collect 16 trunk or wet node signals (active or passive input); as dry contact input or sensor input (NPN or PNP), jumper common positive or negative input can be set; as active input, polarity automatic conversion does not need jumper switching; The 6-way relay can be controlled by MODBUS bus. The module adopts Modbus-RTU communication, and can directly adapt to PLC, DCS and various domestic configuration software.
Switch input and relay input, power input, RS485 communication electrical signals are isolated from each other, effectively suppressing all kinds of serial mode and common mode interference, and ensuring the reliable operation of the module.
Two. Characteristic
1. The Modbus-RTU protocol is adopted.
2. Signal acquisition, relay output, power supply, RS485 communication, electrical signals are isolated from each other.
Three RS485The communication signal output interface adopts over voltage and over current double protection.
4. The input signal type and communication format can be set by software.
Five Power polarity protection.
Six Flexible open signal setting
1) When set to active input, the open signal can be either a common or a common negative input simultaneously.
2) When the input is set to dry contact, simply connect the DI input to the DI common end.

Six. Module indication light and switch function description
1. POW/SET;Module work status indication
A.Green lights: modules are working. B. red light: module has configuration parameter to write, need to power up again.
2. TXD/RXD:Communication status indication
A.Green light: communication receives data B. red light flashes: module is sending data.
C.The green light is always bright: the communication RS485 line on DATA+ and DATA- is reversed or the connection is broken.
3. Module left reset switch use
1) When the communication parameters (module address, baud rate, check bit) are not known or the communication parameters are misplaced, the solution is to reset the communication parameters. Five seconds later, the module [POW/SET] red indicator lights on and the reset switch is opened. At this time, the communication can be achieved. The parameters have been reset, so long as the power supply of the module is powered off and restarted once, then the communication parameters of the module have been reset.
2) After the reset, the communication parameters are: 1, baud rate: 9600bps, check bit: none.
