Number of SSRs That Can
be Connected in Parallel
Compact low-cost
models with quick-
connect terminals
• Concept behind the Number of SSRs That
Can Be Connected in Parallel
(A): The maximum load current for the voltage
output (to drive SSRs) for the Temperature
Controller is 21 mA.
(B): The input impedance for SSRs is 7 mA
(G3NA).
In this case, the number of SSRs that can
be connected in parallel is (A) ÷ (B),
therefore 3.
The maximum load current in the connection
example is 21 mA.

Two-channel SSR outputs can be
connected to models with TC2@-
QNHB.
The number of SSRs that can be
connected for each channel is listed
on the right.
Four-channel SSR outputs can be
connected to models with TC4.
The number of SSRs that can be
connected for each channel is listed
on the right.
Two current output channels can be
connected to the TC2@-CNB.
