Digital I/O Modules


Remote RS-485 data acquisition modules offer digital, counter or relay I/O with Modbus RTU for industrial facility monitoring and management.

  • ADAM-4050


    The ADAM-4050 features seven digital input channels and eight digital output channels. The outputs are open-collector transistor switches that you can control from the host computer. You can also use the switches to control solid-state relays, which in turn can control heaters, pumps and power equipment. The host computer can use the module's digital inputs to determine the state of limit or safety switches or remote digital signals.


  • ADAM-4051


    The ADAM-4051 is a 16-ch. Digital Input Module, built with 2500 VDC optical isolation, suitable for critical applications. Different from other modules, the ADAM-4051 accepts 10~50V input voltage to fit various digital signals, such as 12 VDC, 24 VDC, 48 VDC. Moreover, users can read the current status from the LED indications on the front panel.


  • ADAM-4052


    The ADAM-4052 provides eight digital input channels: six fully independent isolated channels and two isolated channels with a common ground. All have 5000 V RMS isolation to prevent ground loop effects and prevent damage from power surges on the input lines.


  • ADAM-4053


    The ADAM-4053 provides 16 digital input channels for dry contact or wet contact signals. For dry contact, effective distance from DI to contact point is up to 500 m.


  • ADAM-4055


    The ADAM-4055 offers 8-ch. isolated digital inputs and 8-ch. isolated digital outputs for critical applications. The inputs accept 10~50 V voltage, and the outputs supply 5~40 VDC open collector. Considered to be user-friendly. The ADAM-4055 is also built with LED indicator for easy status reading.


  • ADAM-4056S


    12-ch Sink Type Isolated Digital Output Module with Modbus


  • ADAM-4056SO


    12-channel Source Type Isolated Digital Output Module


  • ADAM-4060


    The ADAM Relay Output Module is a low-cost alternative to SSR modules. The ADAM Relay Output Module provides four relay channels, two of Form A and two of Form C. This module is excellent for ON/OFF control or low-power switching applications.


  • ADAM-4068


    The ADAM-4068 relay module is controlled remotely and store configuration data in EEPROM. The ADAM-4068 provides 4/8 channels, half being Form A and the rest being Form C. These modules are excellent for on/off control or low-power switching applications.


  • ADAM-4069


    ADAM-4069 is designed for on/off control in high-voltage applications. The major feature of ADAM-4069 is its power relay rating at 240 V AC and 5 A. This range can satisfy most requirements for driving externally controlled devices such as lights, fans, alarm systems, and various electronic devices in industrial automation, security, building and home automation applications. ADAM-4069 also supports the Modbus/RTU protocol and ADAM ASCII commands. Besides, it provides four form A channels and four form C channels.


  • ADAM-4080


    ADAM-4080/4080D Counter/frequency input module has two 32-bit counter input channels (counter 0 and counter 1)with built-in programmable timer for frequency measurement. These cost-effective modules let you monitor counter/frequency data as measurements are taken.
