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.

EJ1N-TC2

@-CNB

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.

Four 480-VAC

models

(10 A/20 A/40A)

One 240-VAC

model

(75 A/95 A)

· Up to eight G3ZA or G3PW can be

connected to each Basic Unit.

Can be mounted side by side
