•
Load voltage = 40 V max.

Load current = 50 mA max.
RMI-QE outputs
There are five outputs:
•
Probe status 1 (SSR).
•
Probe status 2a (5 V isolated driven skip).
•
Probe status 2b (driven at power supply voltage).
•
Error (SSR).
•
Low battery (SSR).
All outputs can be inverted by using switches SW1 and SW2, (see page 2.10,
“Switches SW1 and
SW2”
, for further information).
Probe status 1, Error, Low battery (SSR):

Output voltages
Probe status 2b (driven at power supply voltage):
Output voltages
The “LOW BATTERY/START”, “PROBE STATUS”, “ERROR” and “SIGNAL” LEDs will start flashing red
when an output overload has occurred. All outputs will be switched off. If this occurs, turn off the power
supply and remove the source of the problem. Turning on the power supply will reset the RMI-QE.
