Product information

Description IOMB-03

IOMB-03 is used to collect and distribute analogue and digital signals to and from regulators (DUC) using Modbus RTU communication.

IOMB-03 is an IP54 enclosed I/O module that transmits measurement and control signals via Modbus to and from DUC regulators. IOMB-03 has 3 digital in and outputs and 3 analogue in and outputs.

The analogue inputs can be configured (via jumpers) to receive either 0-10V or temperature sensor (Pt1000/Ni1000LG). Choice of Pt1000 or Ni1000LG is set on the Modbus register 4×0026-28. The analogue outputs have 0-10V output.

The digital in and outputs both have an amber LED. The green operation LED blinks during Modbus communication.

Addressing, choice of parity and baud rate is set with DIP switches. IOMB-03 should be de-energised at these settings.

The housing has 6 M16 and 2 M20 cable fittings.

Selectable default function: IOMB-03 has a selectable function for dealing with interruptions in the Modbus communication. This means that the three digital and three analogue outputs can be set individually should the Modbus communication be interrupted for a certain amount of time. The time for communication interruption before the default function kicks in can be set between 1 and 600 seconds. If set to 0 seconds then the function is deactivated (factory setting).

As an accessory, a Modbus-IP gateway is available for retrofit.

IOMB-03 is maintenance-free.
