OUTPUT PORTS The field I O interface to the carrier board is provided through connector P2 refer to Table 2 1 Individual Solid State Relays SSR s for each channel isolate the field from the control logic for the IOS 445 Channels are isolated from each other in groups of eight There are eight channels to a group or port Because the output lines of a single port share a common connection individual outputs are not isolated from each other within the same port However separate port commons are provided to facilitate port to port isolation 32 Single Pole Single Throw Normally Open SPST NO 1 Form A SSR outputs are controlled by this module Each group of eight channels can be connected directly to positive or negative supplies for high hot side switching Alternatively each group of eight channels can be connected to common for low side switching Socketed pull up resistors are provided for low side switching applications These resistors should be removed if high side switching is needed In low side switching applications the resistor values can be changed e g lower values will provide a faster pull up while a higher values will keep power dissipation from becoming a problem at higher voltages see Specifications in Chapter 6 for details The SSR s are controlled by output registers within the FPGA Writing a 1 to the output register will turn the switch ON closed circuit while writing a 0 will turn it OF

F open circuit Readback of the output state is accomplished by reading the output registers However for complete confidence in output control loopback should be performed This may be accomplished using the IOS 440 isolated digital input module refer to OS 440 IOS 445 LOOPBACK CONNECTIONS The SSR s employed are rated for a much higher voltage than specified However the field connector and printed circuit board foil spacings limit applied voltages to 60VDC or AC peak Each port group of eight channels has a single common Since the connectors and cables are rated to 1A maximum per pin then each port is limited to that total current Thus the sum of currents conducted by the 8 channels must stay below that total see specifications in Chapter 6 for details The low on resistance of the SSR s helps reduce their power dissipation when they conduct high currents however given the large number of channels on the board adequate air circulation must be maintained The SSR s used in the IOS 445 are very rugged and contain built in current limiting for their protection They provide clean bounce free switching and can replace electromechanical relays in many applications SSR switching speeds are comparable to electromechanical relays 1mS typical but are slow compared to high speed optocouplers Output operation is Fail safe That is the outputs are always OFF upon power up reset and are automatically cleared followin
