MB0020 Input Controller
High-Speed Data Rates
Multiple serial communication (RS-485) speed selection from 9.6kbps to 115.2kbps.
Device ID
MB0020 Controller can be uniquely identified over the network. Device ID is set through specific Modbus register.
Network Security
All configurations changes are protected via password setting, either through standard network protocol access.
Analogue Input Channels
High speed 12-bits A/D converter with programmable gain amplifier yields an accurate reading on analogue input points.
Status Indicator
Operational activity on each individual channel of DIs are conveniently indicated by LED, so as the Operation.
Reset Switch
A Reset Switch has been provided for system reset without power removal (Warm Start operation).
Firmware Upgrade / Configuration
The controller firmware can be upgraded either through RS-485 with built-in bootloader. Network communication and operation parameters can be changed with Modbus register(s).
Robust System Operation
Software watchdog timer is provided for high reliability operation.
Ease of Installation
All I/Os are connected via field removable terminal block connectors for easy maintenance. The controller casing fits standard DIN rail mounting.
