11.2.2 Digital output (IO-2)
The device has four isolated digital outputs with a shared common pin. The digital
outputs are polarity free. The digital output can be used for controlling low current
external devices. The output is a CMOS relay which is protected by a PTC type
fuse. The output is capable of handling a continuous current of 100 mA maximum
at an ambient temperature of 20°C.
11.2.3 Analog input (IO-2)
Table 23: Analog input IO-2 description
Parameter Value Note
Current measuring range 4...20 mA, ±1.5 mA
(-10...+55°C, 4...20
mA)
Positive 15%
Input impedance 250 Ω Current input
Maximum withstanding inputs 35 mA Current input

11.3 DC output
The input voltage to the power supply connector is circulated back to the I/O
connector of the device. This DC output can be used, for example, together with
digital outputs in order to simplify external circuitry and wiring.
