News: 8DI-8DO Industrial-grade Multi-function USB Relay Board PC UART COM Switch Module With Input Indicator Light DC 12V 24V UD85C08


UD85C08 is a newly designed 8-channel USB relay module from eletechsup. It is an upgraded version of the old version. It uses industrial-grade relays and optimizes the layout and wiring of components to make it more durable. It adds 8 input indicators to make it more convenient to observe the input status.








Features:



1: Working voltage: DC 12V/24V optional

2: (DC12V)Standby current (all relays closed) 12MA, 1 relay open 40MA, 2 relays open 68MA, 3 relays open 96MA,4 relays open 122MA,5 relays open 148MA,6 relays open 174MA, 7 relays open 199MA,8 relays open 223MA

3 8 photoelectric isolation Input ports (NPN low level active ), The input port directly controls the relay by default, and can also be set not to control the relay through instructions

4 UART serial port protocol, USB_B female interface (CH340 Chip)

5 USB interface supports Windows(WIN11 WIN10 WIN8 WIN7 WINXP), Linux and MAX OS

6: ''ON'' ''OFF'' ''Self-locking'' ''Interlock'' ''Momentary'' ''Delay'' ''All Relays Open'' ''All Relays Close'' 8 Commands

7 Two kinds of commands: AT command and 8-byte command, the two commands are automatically recognized, no need to switch.

8: Under the ''Delay'' command ,the maximum delay is 9999 seconds(Only AT command)

9 Size: 115 * 63 * 19mm

10 Weight: 124 g

11 Industrial Relays,Maximum load: 10A / 250VAC, 10A / 125VAC, 10A / 30VDC, 10A / 28VDC, 10A / 12VDC

Return command : OpenX, CloseX (X = 1/2/3/4/5/6/7/8/A)







Example 1:



Send command ''AT+D1=0010'', Channel 1 is ''Open'', after delay of 10 seconds, channel 1 is ''Close''



Send command ''AT+D2=0100'', Channel 2 is ''Open'', after delay of 100 seconds, channel 2 is ''Close''







Example 2:



Send command ''AT+L1'', Channel 1 is ''Open'', other Channels is ''Close''



Send command ''AT+L2'', Channel 2 is ''Open'', other Channels is ''Close''









Read input channel status:







Input channel 1: AT+I1



Input channel 2: AT+I2
