1 ACLD-9185 This chapter describes how to install and use the ACLD-9185. 1.1 Introduction The ACLD-9185 is a 16-channel SPDT form C relay output board. It provides 16 electromechanical SPDT relays, which can be used by any ACL series or PCI series boards with digital output channels on 20-pin flat ribbon connector. You can use the 16 on-board relays to control power switches. Each of them matches with one LED to indicate its ON/OFF status and consumes about 33mA when energized.

2 ACLD-9182A This chapter describes how to install and use the ACLD-9182A. 2.1 Introduction The ACLD-9182A is a 16-channel opto-isolated digital input board, which can be connected by any ACL or PCI series digital input board with D/I channels of 20-pin flat ribbon connectors. It is a good solution for preventing floating potential and ground loop problems. Each input channel has a red LED to indicate the ON/OFF status. If the input voltage is high, the LED will be on otherwise the LED is off.

The configurations of connection are shown in the following diagram.
2.3 Usage By setting the JAn and JBn jumpers, you can choose the isolated or dry input(see the 2.3.1). And adjust threshold for isolated mode by tuning VR1(see 2.3.2). 2.3.1 Input Mode Setting There are 2 jumpers (JAn and JBn, n = 0 ~ 15) associated with each digital input channel for configuring the channel as isolated or nonisolated (Dry Contact) input. The digital input channels and their corresponding jumper is shown below.
2.3.2 Adjust Threshold for Isolated Mode The input isolated mode of the ACLD-9182A is actually driven by current instead of voltage level. The logic low means the input leakage current should be less than 1mA, otherwise the input status will be treated as logic High (1). To avoid the logic high voltage as low, the ACLD-9182A is equipped with a variable resistor VR1, which is used to adjust the threshold level for all the 16 isolated input channels.
Where Vin : Input voltage IF: Input current Pw : Power rating Ri : Current Limit resistor For example: If the input voltage is 40V, then the maximum input current is within 20mA, using the above formula : Ri = 40 (V) / 20 (mA) = 2 KΩ Pw = 40 (V) X 20 (mA) = 0.8 W You should choose a 2KΩ resistor and the power rating of this resistor should be 1 Watt. 2.
