INPUT/OUTPUT MODULES, STEP CONTROLLER

Six Stage Relay Module
The MRM 6 converts a 0-10Vdc or 2-10Vdc analogue input into a 6 relay output.

The outputs can also be reversed.

The MRM 6 can be configured for 9 modes of operation:

1. Stage

2. Sequence

3. Power on Stage

4. Power on Sequence

5. Binary

6. Circular Sequence

7. Raise/Lower

8. Cascaded Stage

9. Cascaded Sequence

In addition the MRM 6A can be set, via the jumper links to work with a suitably configured MRM 4 to form a 10 Stage Unit, switching in 1 volt steps.

On/Off/Auto jumpers are provided as an aid for commisioning and LED’s indicate the relay status.

Reaction time is adjustable via potentiometer.

MRM 6

8 Stage Relay Module
Intended for use with DDC controllers to convert an analogue control output to 8 relay outputs.

Link selection of operating mode enables the module to act either as 8 stages of switching, as an 8 output sequencer, or in combination of two modes.

Application include boiler sequencing, boiler staging and compressor sequencing.

LED status indication and On/Off/Auto override links ease commissioning.

The unit can be powered by 24Vac/dc.
