RMI 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 section Switches SW1,
SW2 and start input.
Probe status 1, Error, Low battery (SSR):
‘On’ resistance = 50 ohms max.
Load voltage = 40 V max.
Load current = 100 mA max.
continued on next page
Probe status 2a (5 V isolated driven skip):
Load current = 50 mA max.
Output voltages
Sourcing = 4.2 V min at 10 mA.
= 2.2 V min at 50 mA.
Sinking = 0.4 V max at 10 mA.
= 1.3 V max at 50 mA.
