One Product Introduction
1. Product overview
MBSL32DI32DOThe module is a 32-channel digital isolated input and
32-channel digital transistor isolated output module, which is output through
an isolated RS485 interface. The module adopts standard Modbus RTU
communication, which can be directly adapted Various Host computer
configuration software, PLC, DCS, etc. The module power supply and RS485
communication electrical signals are isolated from each other, effectively
suppressing various serial mode and common mode interference, while also
ensuring the stable and reliable operation of the module.
1,Using RS485 MODBUS RTU standard communication, it can be
networked with host computer configuration software, PLC, industrial touch
screen, etc. With communication status indicator
2, Signal control, power supply, and RS485 communication
electrical signals are isolated from each other.
3, The communication circuit adopts lightning protection and
anti-interference design, Power polarity protection.
4, RS485 communication signal output interface adopts double
protection of overvoltage and overcurrent.
5, Can be widely used in the signal acquisition and control of
industrial field equipment.
6, The communication format can be set by software.
