Product details
Product Introduction
ADM-4188 is an 8-channel isolated digital/switch input/output module that can be widely used for signal acquisition, monitoring, and control of industrial field equipment. It has 8-channel isolated digital input and 8-channel isolated digital output, and the digital output adopts NPN transistor collector collector open circuit output. The communication interface adopts RS-485 interface and supports standard MODBUS RTU protocol, which can be directly connected to configuration software, PLC, DCS industrial control touch screen.
1. Input channel: 8-channel switch contact signal (dry contact) or level signal (wet node)
2. Input polarity: Co negative or co positive input (polarity automatically adapts)
3. Input range: High level (digital 1): 7.5V-30V, Low level (digital 0): 0V -1V
4. Sampling rate: 1000Hz
5. Isolation voltage: 1500V
6. Input count: 16 bits (0~65535), input frequency less than 200HZ
(2) Digital output
1. Output channel: 8-way NPN transistor collector collector open circuit output
2. Load voltage: maximum 40V
3. Load current: 150mA, 625mW
(4) Communication interface
1. Communication protocol: MODBUS-RTU
2. Interface type: Optoelectronic isolation RS-485 interface

5. Check bits: no check, even check, odd check
6. Default parameters: 9600, N， 8, 1 (baud rate and parity can be modified)
(5) System parameters
1. Module size: 104mm x 72mm x 26mm
2. Installation method: 35mm DIN rail installation
3. Working environment: Temperature: -10~65 ℃ Humidity: 0-95%, non condensing
4. Working power supply: DC9~30V less than 3W
Definition of module indicator lights
1. POWER: Power status indicator, constantly on/normal power supply
2. COMM: RS-485 interface communication indication, flashing/module is sending and receiving data
3. DI0~DI7: Digital input indicator, lit/switch input is 1
4. DO0~DO7: Digital output indicator, lit/switch output is 1
Use default communication parameters
When the communication parameters of the module (module address, baud rate, parity) are forgotten, short-circuit the Initiat and DOGND pins and power on the module again. At this time, the communication parameters of the module are (9600, N, 8, 1) and the module address is 01.
When the Initiat and DOGND pins are disconnected, the module communicates using the communication parameters set by the user. The module parameters at the factory are (9600, N, 8, 1) and the module address is 01.
