25IOA08 25IOB16 25IOC32 series products are eletechsup's first PNP Output RS485 IO module. With 8/16/32 channels NPN/PNP Photoelectric isolation input and the same channel 300MADMOS PNP Output.(NPN Output Please select 23IOA08 23IOB16 23IOC24 23IOD32 23IOE48)Features:1. Working voltage: DC 7-25V (9V 12V 24V)2. Working current: 8-50MA3. 8/16/32 photoelectrically isolated input ports, NPN/PNP(optional) 4. 8/16/32 DMOS PNP outputs (high level output, drive current 300MA)5. The default command has multiple output modes: six output modes: Open/Close/Toggle (Self-locking)/Latch(Inter-locking)/Momentary (Non-locking) /Delay .6. The input port can remotely control the output port of another board through the RS485 bus7. MODBUS command 1 supports 03 06 16 function code, MODBUS command 2 supports 01/02/03/05/06/15/16 function code8. The maximum delay under MODBUS command 1 is 255 seconds.9. In MODBUS command mode, up to 64 devices can be supported in parallel.10. The default baud rate is 9600BPS, Can be set :1200/2400/4800/19200/38400/57600/115200BPS11 .Sizes (Only Board): 61x72x18MM (8CH), 106x72x18MM (16CH), 196x72x18MM (32CH)12.
