1. Maximum output current for all digital triac outputs is 0.5A continuous or 1A @ 15% duty cycle for a 10-minute period.
£ Line voltage powered form-C relay output, 0-277VAC / 0-30 VDC, 10A
maximum. For example, 120/240VAC controlling a 3 phase motor
contactor.
£ The line voltage must to be protected by a 10A Circuit breaker to pro-
tect the relay contact output against short circuit/overload conditions.
£ A single 10 amp circuit breaker can be used to protect two or more re-
lay outputs if all connected loads are on the same phase and the total
maximum current to all loads is less than 10A.
SELV circuit cannot be used on a relay output next to another relay
output used with Hazardous voltages (120-240VAC for example).
A Line-to-Line power source can be used only if the maximum Line-
to-Neutral Voltage is less than 120VAC.
