Heat/cool output (3D)
Connect as follows.
Handling Precautions
• When switching small currents, connect a bleeder resistor to
allow current flow of the minimum relay switching input (100 mA
min.).
■
Heat/cool output (5K)
Connect as follows.
Handling Precautions
• Current output and voltage output can be selected by setups
C

and
C

.
Voltage output is reliant on an internal fixed-current circuit.
Set the current value in the setup data so that the optimum volt-
age is obtained matched to the conditions of the SSR in use and
load.
Factory setting: general-purpose SSR voltage value.
