Solenoid Driver, Power Amplifier

Описание

This signal conditioner is a 4-channel barrier with outputs that switch 600 mA to high-power solenoids. It is also used as power amplifier up to a switching frequency of 1 kHz. 4-channel signal conditioner, 24 V DC supply (Power Rail), Output 600 mA per channel, Logic inputs, Common safety-oriented disable input, Line fault detection (LFD), Up to SIL 2 acc. to IEC 61508, Output rated operating current: 600 mA per channel , sustained short-circuit proof and overload-proofpa. Two channels per module can be paralleled. The output current of a parallel combination is 1.2 A. If the supply voltage falls below 18 V, the outputs will be switched off. The outputs are sustained short-circuit proofed and overload-proofed. Lead breakage and short circuit, which is selected via DIP switch, is indicated by a red LED and through the collective error output via Power Rail. With the common disable input (terminals 11 and 12), the auxiliary power for all 4 channels can be switched off simultaneously. This central switch-off is also indicated by a red LED and reported as an error signal to the Power Rail.
