Peripheral Devices

Temperature Sensor and SSR
Connection Example with SSR
Analog values representing temperature,
flowrate, or concentration
Converter, digital panel meter, flowrate
meter, non-contact temperature sensor,
displacement sensor, etc.

Calculating the Maximum Number of
SSRs Connectable in Parallel
A: Max. load current of Digital Controller's
voltage output driving the SSRs is 40 mA for
the E5AR (E5AR-QQ@WW-@ = 21 mA).
B: SSR's input impedance is 7 mA for G3NA
In this case, the maximum number of SSRs
connectable in parallel would be as follows:
A/B = 5
The maximum load current in the
connection example is 40 mA.
