IS/4RM – 0–10 Vdc to 4-relay ON/OFF converter

Transform four 0–10 Vdc signals into four ON/OFF relay commands with the IS/4RM. Adjustable switching thresholds and three operating modes allow the module to be configured according to the system's control requirements.

The output activation thresholds can be set in the 0–10 Vdc range using potentiometers. Hysteresis on the switching points is selectable via jumpers, while red LEDs indicate when the relay outputs are active.

Three operating modes for control and system testing

• Sequencer: uses the signal from one input to control one, two, three, or four relays, depending on the switching thresholds set via potentiometers.
• Independent channels: functions as four separate and independent 0–10 Vdc to ON/OFF converters.
• Manual override: allows for manual control of the outputs to ON or OFF states, to facilitate checks during commissioning.

Power supply: 24 V AC/DC. Protection rating: IP20.

Before purchasing, check the technical data sheet to ensure that the relay contact specifications are suitable for the load to be controlled.
