Action : ON/OFF action
Hysteresis setting range
When thermocouple or RTD input, 0.1 … 100.0 °C (°F)
When DC input, 1 … 1000
(Decimal point place follows the selection.)
Output : Relay contact 1a
Control capacity, 250 V AC, 3 A (resistive load)
250 V AC, 1 A (inductive load cosø =0.4)
Circuit insulation configuration
(*1) When both Main output and Cooling output are Current output type or
Non-contact voltage output type (the SSR drive), A to B is non-isolated.
(*2) When Main output is Current output type or Non-contact voltage output type
(the SSR drive), A to F and A to G are non-isolated.
When Cooling output is Current output type or Non-contact voltage output type
(the SSR drive), B to F and B to G are non-isolated.
Insulation resistance
10M Ω or greater at 500Vdc
Insulation test must not be carried out between A-B in the case of Circuit
insulation configuration (*1), and between A-F, B-F, A-G, B-G, C-D-E and
F-G in the case of Circuit insulation configuration (*2) because they are
non-isolated.
Dielectric strength
Between input terminal and ground terminal, 1.5 kV AC for 1 minute
Between input terminal and power terminal, 1.5 kV AC for 1 minute
Between power terminal and ground terminal, 1.5 kV AC for 1 minute
Between output terminal and ground terminal, 1.5 kV AC for 1 minute
