16BITS 4~20MA ANALOG SINGLE-ENDED INPUT AIN IO MODULE SUPPORT RS485 AND ETHERNET
BL190 Modbus TCP Combined IOprovides 26 IO board options, including digital input/output, analog input/output, thermocouple and resistance temperature detection, etc., which can be combined into more than 10,000 models to meet a variety of application scenarios, and you can select the I/O modules by physical interfaces, protocols, and I/O functions.
The Modbus TCP Ethernet IO Module passing 12 EMC/EMI tests ensures reliability under strong electromagnetic interference.
Ordering Guides
Users can select 1-3 Y series IO boards according to their needs, such as BL190 with 3 Y11 (8DI) can be composed of 24DI Modbus TCP IO module, and also supports mix and match such as BL190 with Y11 (8DI), Y31 (4AI), Y52 (2PT) can be combined into 8DI + 4AI + 2PT Modbus TCP IO Module.
