1 OVERVIEW DOUT16B-2 Digital Output Module is an expansion module which has 16 auxiliary digital output channels. Expansion module status is transmitted to DOUT16B-2 by main control board via RS485. 2 TECHNICAL PARAMETERS Table 2 Technical Parameters Items Contents Working Voltage DC8.0V~ DC35.0V continuous power supply Power Consumption <6W Aux. relay output port 1-16 10A relay for output port 1~4, 7~14. 16A relay for output port 5~6, 15~16. Case Dimension 161.6mm x 89.7mm x 60.
3 MODULE ADDRESS This is a 4-bit in-line DIP switch with 16 coding status, namely 16 module addresses (from 100 to 115). When it is turned to ON, the status is 1. The module address formula is Module Address=1A+2B+4C+8D+100. For example, when ABCD is 0000, the module address is 100. When ABCD is 1000, the module address is 101. When ABCD is 0100, the module address is 102. Similarly, when ABCD is 1111, the module address is 115. The corresponding module addresses of DIP switch are as follows.

5 COMMUNICATION CONFIGURATION AND MODBUS COMMUNICATION PROTOCOL 5.1. RS485 COMMUNICATION PORT DOUT16B-2 is an expansion output module with RS485 communication port, which follows Modbus-RTU communication protocol. Communication Parameters Module Address 100 (range 100-115) Baud Rate 9600bps Data Bit 8-bit Parity Bit None Stop Bit 2-bit 5.2. INFORMATION FRAME FORMAT EXAMPLE 5.2.1. FUNCTION CODE 01H Slave address is 64H (decimal 100), read 10H (decimal 16) status of starting address 64H (decimal 100).
5.2.2. FUNCTION CODE 03H Slave address is 64H (decimal 100), starting address is 1 data of 64H (decimal 100) (2 bytes per data). Table 4 Example Data Address Address Data (Hex) 64H 1 Table 5 Function Code 03H Master Request Example Request Bytes Example (Hex) Slave address 1 64 Send to the slave 64H Function code 1 03 Read point register Starting address 2 00 Starting address is 64H 64 Count Number 2 00 Read 1 data (total 2 bytes) 01 CRC code CC CRC code which calculated by master.
5.2.3. FUNCTION CODE 05H Slave address is 64H (decimal 100), starting address is one status of 64H (decimal 100). Set 64H unit as 1. Table 7 Example Status Data Address Address Data(Hex) 64H 1 Illustration: Hex value FF00 forced status is 1. 0000H is forced as 0. Other values are illegal and do not affect the status.
