R4DB908 is a 2 in 1 RS485&RS232 Digital output module designed and produced by eletechsup. VH3.96 interface, with 8CH 3A NPN output ports with photoelectric isolation. Supports standard MODBUS RTU protocol
Features
1 Working voltage: DC 6-25V
2 Working current: 10-20MA
4 Compatible with Eletechsup command and MODBUS RUT command at the same time, two command control modes
5 Eletechsup command: ON/OFF/Self-locking/Inter-locking/Momentary/Delay
6 MODBUS RTU command support 01/03/05/06/15/16 function codes
7 In MODBUS command mode, up to 247 devices can be supported in parallel.
8 With RS485 and RS232 (DB9) dual bus interfaces, both interfaces can be used at the same time
9 8-channel 3A MOS tube output
10 The terminal block uses VH3.96 terminal (the terminal block needs to be purchased separately)
11 Size: 96*72*15MM
12 Weight: 45g

1 With RS485 and RS232(DB9) interfaces, the two interfaces are independent of each other and can be used alone or at the same time.
2 8-channel MOS tube output (O1-O8), maximum drive capacity 1-4A, NPN low-level output, which can drive resistive and inductive loads such as LED relays, low-power motors, and solenoid valves.
3. If communication fails, you can short the RES jumper for 5 seconds to restore factory settings.
4 By default, the Eletechsup command and the Modbus RTU command can be used at the same time. The two pads of M0 are welded together, and only the Modbus RTU command can be used.
