The PS-104 is a power supply for HVAC system.
It converts 230VAC to 12VDC for thermostat operation and through relays, transfers commands from thermostat to operate HVAC system.
It offers 8 relay outputs to control HVAC system and 3 inputs for Temperature Sensors.
• Main Supply - 230VAC
• 8 x 230VAC outputs – each 6A (resistive), or 3A (inductive), total ≤ 9A
• 7 x 12VDC inputs
• 3 inputs for temperature sensors
• Inputs & outputs are terminal blocks, screw connector
