*1 Inputs are assigned to the four external input lines. Non-voltage input rating : ON voltage 2 V or lower, OFF current 0.02 mA or lower. Voltage input rating : maximum input rating is 30 V, ON voltage 7.5 V or higher, OFF current 0.05 mA or below. *2 NPN open collector output rating : maximum 50 mA/ch (20 mA/ch when expansion units are added) 30 V or below, residual voltage 1 V or below (1.5 V or below when adding 6 or more expansion units, including main unit). PNP open collector output rating : maximum 50 mA/ch (20 mA/ch when expansion units are added) below power supply voltage, residual voltage 2 V or below (2.5 V or below when adding 6 or more expansion units, including main unit). *3 Use 20 to 30 V as power supply voltage when 6 or more expansion units, including main unit, are to be used. *4 When connecting 8 units for DL connection, maximum power is consumption 11.3 W.
