Note: 1. When using the heater burnout alarm function with a standard model, the Linear Output Module cannot be used for the control
outputs (heat). The Digital Controller provides transfer outputs at 4 to 20 mA for the PV and other values and control outputs at
4 to 20 mA for the current outputs.
2. E5EK-PRR2/E5AK-PRR2 controllers are supplied with relay output. The relay output is not compatible with any other module.
3. Position-proportional models are intended for motorized values (not 4-20 mA modulating valves). These use two relays (“open”
and “close”) which will turn a motor clockwise or counter-clockwise, thus opening or closing the valve.
