SSR
2 to 22mAdc
With current adjustment function
(setup: C78)
Voltage output is reliant on an internal fixed-current circuit.
Set the current value in the setup data so that the optimum voltage is obtained
matched to the conditions of the SSR in use and load.
Factory setting: general-purpose SSR voltage value.
■ Heat/cool output (3D)
Connect as follows.

Output 1
Contact rating, resistive load
5A (30Vdc/120Vac)
4A (240Vac)
Minimum switching current: 100mA
Output 2
Contact rating, resistive load
5A (30Vdc/120Vac)
4A (240Vac)
Minimum switching current: 100mA
When switching small currents, connect a bleeder resistor to allow current flow of
the minimum relay switching input (100mA min.).

■ Voltage output (6D)
Connect as follows.
Current output and voltage output can be selected by setups C 7 5 and C 7 6 .
Voltage output is reliant on an internal fixed-current circuit.
Set the current value in the setup data so that the optimum voltage is obtained
matched to the conditions of the SSR in use and load.
Factory setting: general-purpose SSR voltage value.
