1 - PRESENTATION
The IM–111 (Universal Modbus Indicator) is an
indicator capable of acquiring signals as electric
voltages, currents, frequency, temperature sensors
like Pt100, among others, and also capable of
retransmitting them in standard 0/4 –20 mA or 0/2 –
10 Vdc. The indicator is equipped with two solid state
relays that can be linked to alarms.
The process variable is shown in the frontal of the
IM–111 through the display for easier visualization
and configuration.
The IM–111 is equipped with serial
communications and can be connected to a
Modbus/RTU network, suitable for SCADA systems. It also comes with DLGTools software, used
to configure all DLG Automation via ModBus network, free of charge.
The indicator is fully configurable via the frontal keypad or by the freely available DLG Tools
software, without the need for jumpers.
