Page 3: Using Cmos Circuitry In Industrial Control
IMPORTANT! Please read the following section before installing your product: Octagon’s products are designed to be high in performance while consuming very little power. In order to maintain this advantage, CMOS circuitry is used. CMOS chips have specific needs and some special requirements that the user must be aware of. - Page 4 The most common failures on CPU cards are over voltage of the power supply, static discharge, and damage to the serial and parallel ports. On expansion cards, the most common failures are static discharge, over voltage of inputs, over current of outputs, and misuse of the CMOS circuitry with regards to power supply sequencing.
- Page 5 Under rated power supply: The board may fail to boot due to an under rated power supply. It is important that a quality power supply be used with Octagon Systems cards that has sufficient current capacity, line and load regulation, hold up time, current limiting, and minimum ripple.

Each channel can switch loads up to 200 mA and 50V. Signals may be AC or DC. Each output is isolated from each other and the system. As shipped, the 5624 will accept signals from 9–58V DC. A plug–in resistor pack allows the user to accommodate ranges from 3V to 84V. -

Page 13: Base Address
As shipped, the base address is 100H, which is jumper configuration W1[1-2] [3-4] [5-6]. If there is another card in your system with a base address of 100H, you must use a different base address for the 5624 or the other expansion card. -
Page 14: Ports
≡ ≡ Ports Inputs The 5624 inputs are optically isolated and are capable of receiving high voltage level inputs. If the input voltage level is below the threshold level, a logic zero is read. If the input voltage is above the threshold voltage, a logic one is read. -
Page 15: Example
'Read 2nd 8 bit port from address 104H B = INP (&H104) Outputs The 5624 provides eight isolated solid–state relays for outputs. The outputs may switch both AC and DC loads. The loads may be connected to either the OUT+ or the OUT– terminal. The DC load voltage may be connected in either polarity. -
Page 16: Table 5 J1 Connector - Input Lines
Port pinouts J1 and J2 are 26–position headers. Of the 16 input lines, the first 12, IN0 to IN11, are connected to J1. The remaining 4 input lines, IN12 to IN15, are connected to J2. All 8 output lines are connected to J2. Refer to Tables 5 and 6. -
