Module of digital inputs/outputs M-DI3/DO5
• Communication line RS485, protocol ModBus RTU
• 3 digital inputs
• Two parallel action modes – digital inputs and
counting digital inputs
• Software configured sampling time for both modes
• Hardware configured input type
• 5 digital two-state outputs – relay (M-DI3/DO5R)
triac (M-DI3/DO5TC, M-DI3/DO5TV)
Description
M-DI3/DO5 is the I/O module with ModBus communication. The device is comprised of 3 digital inputs and 5 galvanic separated
digital outputs. Modules with triac outputs are prodused in two versions. M-DI3/DO5TC is designed to switch regular and
inductive loads up to 1A. M-DI3/DO5TV is designed to switch high output impedance loads off state up to 0,5 A. Type M-DI3/DO5
must not be used to switch of inductive loads.
The device communicates with ModBus protocol on the line RS485. The device is build in the compact box designed for mounting
on the 35mm DIN rail. Indicators LED are located on the front panel. These can be indicated: power supply, communication error,
status of inputs.
