 Function Introduction:
 The WJ188 remote I/O module can be used to measure 8 analog signals.
 1. Analog signal input
 12 bit acquisition accuracy, 8 analog signal inputs. All signal input ranges have been calibrated before the product
 leaves the factory. During use, users can also easily program and calibrate themselves. Please refer to the product
 selection for specific current or voltage input range.
 2. Communication Protocol
 Communication interface: RJ-45 network interface. The two indicator lights at the network port position, the Link
 light (green light) stays on and the Data light (yellow light) stays on after the network cable is plugged in.
 Communication protocol: MODBUS TCP protocol is adopted to achieve industrial Ethernet data exchange. It can
 also communicate with modules through TCP sockets.
 Network cache: 2K bytes (for both sending and receiving)
 Communication response time: less than 10mS.
 3. Anti interference
 There is a transient suppression diode inside the module, which can effectively suppress various surge pulses and
 protect the module.
